Dsc Pc4820 User manual

S e c t i o n 1

The PC4820 is a versatile Dual Card ReaderAccess Control

module which will enable you to meet the most

demanding access control requirements of an installation.

The PC4820 is monitored and programmed via the

PC4010/4020 control panel. Up to 16 PC4820 modules can

be connected to a PC4010/4020 via a 4-conductor Combus,

using standard, unshielded station wire.

Each PC4820 is capable of providing supervision for two

door inputs which may to assigned to any PC4010/4020

zone. Each door contact may be configured for any zone

end of line option which the control panel can provide.

Each of the two PC4820 Access Card Readers can be

programmed to function independently on different

doors, or together controlling access for both sides of one

door.

Control of the access points can be performed using a

variety of equipment. The PC4820 supports four different

types of card readers: the Polaris magnetic strip reader,

the Shadow Prox proximity card reader, the HID proximity

readers, and 26-bit standard Wiegand card readers. The

PC4820 also supports the use of any request to exit device

including the T-REX exit detector.

Introduction

S e c t i o n 2

2.1 Plan Your Installation

When designing a security system with access control it

is best to first lay out the system on paper. This will help

determine the total number of zones, additional expanders,

access control points and other system components that

will be required to complete the installation.

When the location of all points of access are known,

appropriate points may be chosen for access control. When

working from the layout, be sure to locate the PC4820

module so that the wire runs from each door will be as

short as possible.

When deciding the placement of the access points and

module, remember to check the capacitance limit for the

wire you are using for the Combus. Follow the steps

outlined in your PC4010/4020 v3.0 Installation Manual

(Section 2.4 “Capacitance Limits”).

NOTE: Do not run the Combus to the PC4820 in shielded

cable.

2.2 Installation Steps

Once the location of the PC4820 and each access point is

determined, follow the installation steps outlined below.

1 Installation of PC4820 and accessories:

The PC4820 controller cabinet has been designed for

surface mounting. The cabinet is large enough to

accommodate the battery backup supply and the

necessary wiring connections for most applications.

The cabinet should be mounted indoors, in a dry,

secure location providing normal temperature,

humidity levels and access to an earth ground

connection. The location should be easily accessible

for servicing the equipment, and it is recommended

that each PC4820 module be near the doors it controls.

If the PC4820 is within the Access controlled area, keys

for the controlled doors must be made available so

that the PC4820 can be accessed for servicing.

Connect the various devices for each access door

according to the diagram below:

A. Access card readers should be located 107cm (42")

from the floor.

B. Connect door strikes using standard 18-gauge cable.

Recommended door strikes are electric “Continuous

Duty” devices which, when power is cut, will remain

in a locked or “secured” state. When using magnetic

locks, follow local regulations on the use of these

devices.

CAUTION – Local regulations may prohibit “Lock on

Power Failure” if the door is used as a Fire Escape route.

C. Door contact must be hardwired directly to the PC4820.

Wireless or addressable contacts may not be used.

D. Install a T-REX exit detector and door alarm (optional)

inside of the protected area. (See T-REX Installation

Instructions for details on wiring and proper

mounting locations.)

2 Tamper protection

A tamper switch may be installed on the cabinet to

protect it from unauthorized entry. The normally

closed tamper switch is connected to the TAMP and

GND (on right side of the PC4820). If the tamper

switch is not used, the TAMP terminal must be

terminated to any GND terminal with a wire.

3 Connect all inputs, outputs, door locking

devices and card readers

Follow the instructions outlined in the sections

below for installing each type of device.

4 Power requirements

Install a 16-18VAC/40VA transformer outside the

cabinet. Connect the red battery lead to the positive

terminal and the black battery lead to the negative

terminal.

NOTE: Do not apply power until all wiring is complete.

Both the AC and battery connections must be made in

order for the PC4820 to function properly. Connect

the battery before connecting the AC.

2.3 Inputs – POST, ARM and REX

The door inputs are capable of following any type of

supervision. Choose the end of line configuration (Normally

Closed Loops, Single End of Line or Double End of Line)

which you have selected for the rest of the security system.

The POST, ARM and REX inputs are for Auto-arm

postponement, Arming buttons and Request to Exit

devices, respectively. These inputs will only be capable of

Normally Closed Loops or Single End of Line resistors.

When using Double End of Line supervision, these inputs

must only be wired for Single End of Line configuration.

Please see section 3.5 “ZoneAssignment forAccess Doors”

for information on door input zone programming.

POST Inputs

When enabled, this PC4820 input allows postponement of

Autoarm of the PC4010/4020 for the partitions selected in

Installation and Wiring

To PC4820 Access

Control Module (See

Access Control

ModuleWiring

Diagrams for details)

Installation and Wiring

the Arm/Disarm mask. To postpone an autoarm, the user

must present their access card (during the autoarm pre-

alert) and activate the device connected to the POST input.

Typically the POST input will be a push button device

mounted next to the access card reader (107cm (42") from

the floor) which is assigned to the partition(s).

The PC4010/4020 will send an Autoarm Abort reporting

code to the monitoring station if the reporting code is

programmed. The autoarm will restart at the end of the

Postpone Arm time (ref # [00020305]) unless the partition

has been manually rearmed. The autoarm may be

postponed as many times as desired.

NOTE: To postpone an autoarm, the user must be

assigned to the partition(s) being armed, and the user’s

access card must have the disarm attribute enabled.

See your PC4010/4020 Instruction Manual for

information on programming access codes and cards.

ARM Inputs

When enabled, this PC4820 input will allow designated

users to arm the selected partitions on the PC4010/4020.

To arm the partition, the user must first ensure that the

partition area(s) to be armed is secure (close all protected

doors and stop movement in areas covered by motion

detectors). The user should present the access card and

activate the device connected to the ARM input. The exit

delay will begin. Typically the ARM input will be

connected to a push button device and should be

mounted next to the access card reader (107cm (42") from

the floor) which is assigned to the partition(s).

NOTE: To arm partitions, the user must be assigned to

the partition(s) being armed, and the user’s access card

must have the arm attribute enabled. See your PC4010/

4020 Instruction Manual for information on

programming access codes and cards.

REX Inputs

A Request to Exit device can be used on the inside of the

secured area to provide a method of unlocking the door

without the need for an access card reader on the inside

of the door. When the REX device is tripped, the door

will unlock. This will also allow the door to be opened

without the door being “Forced open.” Request to exit

devices can be of many different types. Be sure to read

the installation sheets provided with each unit for proper

installation for the REX devices.

2.4 Outputs – LED, BUZ and OUT Terminals

LED Outputs

The LED outputs for Out Door 1 and Out Door 2 are used

for controlling the LED on the access card readers. This

allows the PC4820 to provide visual feedback when the

access card is presented to the reader. Connect the wire

from the reader indicated as LED to the LED terminal of

the selected output.

When using this output to switch an external device, the

negative terminal of the device must be connected to the

LED output terminal. The positive terminal of the external

device must be connected to the AUX+ terminal.

BUZ Outputs

The BUZ outputs for Out Door 1 and Out Door 2 are

used for controlling the buzzer of the access card readers.

This will allow the PC4820 to provide audible feedback

to indicate error conditions. Connect the wire indicated

as buzzer to the BUZ terminal of the selected output.

When using this output to switch an external device, the

negative terminal of the device must be connected to the

BUZ output terminal. The positive terminal of the external

device must be connected to the AUX+ terminal.

OUT Outputs

Reserved for future use.

2.5 Door Locking Devices – LK1 & LK2 Terminals

Connect door locks to LK1 and LK2. Each lock output

can provide up to 250mA at 12VDC. Always check local

regulations concerning the installation of magnetic

locking devices.

The locking device outputs are controlled according to

the installer programmed parameters for allowing access

to, or unlocking the doors according to schedules. These

door locking device outputs can operate DC-powered

locking devices such as electromechanical strikes and can

be configured to operate in fail-safe or fail-secure modes

(normal or reverse action). The typical maximum DC for

each lock output is 250mA.

WARNING: According to local regulations, there may

be strict limitations to installing magnetic locks or

other similar locking devices on doors used for exit.

Be sure to check local regulations before installing any

door locking device.

2.6 Access Card Readers

Each PC4820 module can control two access card readers.

These can be installed on one door to control both entry

and exit, or on two separate doors to control access in

one direction only. Using the proper cable, the readers

may be located up to 150 meters (500 feet) from the

PC4820 module. The access card readers should be

mounted 107cm (42") from the floor.

WARNING: Connecting the Red wire lead (or power

lead) of a 5VDC reader to the 12VDC terminal may

damage the reader. See reader installation procedure

for proper power connection.

Using Two Readers to Control One Door

When using the Two Readers option, the PC4820 can use

both readers to control entry and exit from a single access

control point. Each reader can be programmed to have

its own access levels (allowing the ability to separately

control entry and exit permissions for each door on the

system), and schedules. See section 3.2 “Door Options”

for programming information.

NOTE: When using the Two Reader option, the Door

2 input must be terminated to any COM terminal.

Access Card / Keypad Readers

Access card readers with integrated keypads may be used

with the PC4820. In order to use this reader type, the

user must first present their access card. The LED on the

reader will flash twice every second to indicate to the

user that the reader is waiting for an access code to be

entered. The user will have 15 seconds to enter their access

code. If the code is entered successfully, the door will be

unlocked. The access code entered must be the correct

code for the access card used, otherwise access will not

be granted, even if the code entered is a valid code on the

system. When access is denied to the user due to a wrong/

invalid code being entered, or time has expired waiting

for the access code, the LED on the reader will flash 3 times

every second and the buzzer will give an audible beep 3

times every second to indicate that access was denied.

Reader LED Flash Rates

Most access card readers will have an LED output to

provide visual feedback when the access card is presented

to the reader. The light will flash in different ways to

indicate the following conditions:

LED State Access Condition

Steady Red Door is locked

Steady Green Door is unlocked –

Access granted

Slow flash (state changes The partition that the

every half second) Arm/Disarm mask is

assigned to is armed

Medium Flash (state changes Waiting for a Privileged

three times every second) card to be presented

Fast flash (State change Access denied/Time

four times every second) expired waiting for a

privileged card.

Buzzer Operation

Most access card readers will have a buzzer output to

provide audible feedback. The Buzzer output may be

connected to operate local warning devices for the

following conditions:

• The access controlled door has been forced open.

The buzzer will activate and remain active until the

door has been closed.

• The access controlled door has been left open too

long. The buzzer will activate and remain active

until the door has been closed. The buzzer will pulse

on and off for the last half of the programmed Door

Open Time to indicate that the Door Open Too Long

event is about to occur.

Programming of the PC4820 is performed at the PC4010/

4020 control panel in Installer’s Programming mode.

Refer to Section 4 “How to Program” of the PC4010/4020

Installation Manual for instructions.

The following programming sections must be

programmed for each PC4820 enrolled on the system. To

select a module, enter reference number [0011XX] where

“XX” refers to the PC4820 module number.

The control panel will transfer all necessary information

(access codes, scheduling, etc.) to each PC4820 module

whenever one of the following occurs:

1. the main panel is powered up

2. installer’s mode is exited

3. a PC4820 loses and then restores communication

with the control panel

4. a PC4820 is hardware defaulted

5. a PC4820 is enrolled

6. a downloading session has disconnected.

The data transfer can take up to 2.5 minutes per PC4820

module. When the transfer is completed, all keypads will

beep 16 times. Changes to PC4820 programming will not

take effect until the data transfer is complete.

3.1 Programming Reader Types

Ref # [0011XX00] where XX = PC4820 module #

The PC4820 is capable of supporting different types of access

card readers. The same type of reader must be used on both

doors of an access card module, but different modules may

use different reader types. Enter the 2-digit code for the

reader type you are installing on the selected zone.

00 Polaris 1- Magnetic card reader. 7 Digits with clock

and data.

01 Shadow Prox - Extended range proximity reader

SH5, SH6, SH7, SH-VR 32 Bits.

02 26 Bit Standard Wiegand reader, HID Proximity

readers

The default access card reader type is 00 (Polaris 1).

3.2 Reader Options

Ref # [0011XX01] where XX = module #

This section contains the programming for the selected

PC4820. First, you must select which of the two doors to

program. Use the arrow (< >) keys to scroll to either Door

1 or Door 2 and press the [*] key to select. Aseries of toggle

options will be available for each door. Again, use the

arrow (< >) keys to scroll through each option and press

the [*] key to turn the selected option on or off.

The options available for each door are as follows:

•Lock Reversed: If enabled, power will be applied to

lock the door. The lock will remain closed when idle

and will deactivate when a valid access card is used

to open the door. The programming for this option is

dependent on the type of locking device being used.

Check the installation sheet provided with the locking

device to see what is required for power.

If disabled, power will be applied to unlock the door.

This option is for use with “Fail Secure” devices such

as electronic door strikes. (Default = No)

•Unlock on REX: If enabled, tripping a Request To

Exit device will cause the door to unlock for the

programmed Door Unlock time (see Section 3.4

“Door Times”). If disabled, tripping the Request To

Exit device will not cause the door to unlock.

(Default = Yes)

•Flash When Arm: If enabled, the armed status of the

assigned partition(s) will be indicated by the light on

the reader assigned to the door. The LED will flash

slowly for the duration of the armed period.

NOTE: The partition(s) to which the door’s zone is

assigned must also be selected in the Arm/Disarm Mask

for proper operation of this function.

If disabled, the LED on the access card reader will

not indicate the armed status. (Default = Yes)

•Relock On Arm: If enabled, a Request To Arm will

relock the door when the arm input is activated. If

disabled, a Request to Arm will not relock the door.

(Default = No)

•Lock On Close: If enabled, a door unlocked by an

access card or by a REX device will lock once the

zone is opened and then closed. If disabled, a door

unlocked by an access card or by a REX device will

relock once the zone is opened. (Default = No)

•Code Required: If enabled, a valid access code must

be entered at an adjacent keypad in addition to the

card swipe in order for the door to unlock. If

disabled, no code will be required. (Default = No)

•LED Reversed: If enabled, the normal state of the

LED output on the PC4820 will be an open collector.

If disabled, the output’s normal state will be low.

(Default = No)

•Two Readers: If enabled, both “doors” (card readers)

will be assigned to the same zone. This will allow

the PC4820 to control access both into and out of a

secured area at a single access point. The zone and

partition assignment of both doors on the PC4010/

4020 must be the same. (See section 3.5 “Zone

Assignment for Access Doors” and your PC4010/

4020 Programming Manual for information on zone

and partition programming.)

Any time an access card is presented at one reader

to open the door, the second reader will also allow

access. This will prevent a door forced open event

(both lock outputs will unlock).

Each door can still be programmed to have its own

access levels (allowing the ability to control both

entry and exit permissions for each door on the

system), and schedules.

NOTE: This option can only be enabled for Door 1.

If disabled, doors 1 and 2 will have their own zone

and partition assignments. (Default = No)

3.3 Arming and Disarming with Access Cards

The PC4820 can be set up so that users may arm and

disarm, or postpone the autoarm of any active partition

on the system. To set up partitions to be armed and

disarmed from an access control module, the following

must be programed:

1. The user’s access card must be assigned to the

appropriate partition(s); an access level must be

assigned to the access card; and the access card must

have the arm and or disarm attribute enabled (see

section 3.8 “Programming Access Cards”).

2. The access door must be assigned a PC4010/4020

zone (see section 3.5 “Zone Assignment for Access

Doors”), and the zone must be assigned to the

appropriate partitions (see below).

3. The Arm/Disarm mask must be programmed to

include the partition(s) that are to be armed/

disarmed from that access card reader (see below).

4. The Postpone Arm, Arm Request and Disarm

Request schedules must be programmed with a date

schedule other than [00] (see section 3.6 “Access

Door Schedules”).

HINT: When using the arming/disarming options of the

PC4820, the use of Bell Squawk and a Partition Status

output will allow for clear indication of the armed status

of the partition(s). These options can be enabled/disabled

on each partition (see your PC4010/4020 Installation

Manual for more information on programming partitions).

Arm/Disarm Partition Mask

Ref # [0011XX01YY01] where XX = module #; YY = door #

In this section select the partition(s) which users will be

able to arm and/or disarm when they present the

appropriate access card at the reader for the access door.

NOTE: The zone assigned to the door must be assigned

to the same partitions selected in the Arm/Disarm

Partition Mask (Partition Programming, reference #

[0100XX03], where XX = partition #).

3.4 Door Times

Ref # [0011XX01YY02] where XX = module #; YY = door #

Door Unlock Time

The amount of time that the door will remain unlocked

after a valid access card has been presented is

programmed in this section. This is also the Request To

Exit time period. The default setting is 10 seconds. Valid

entries are from 001-255 seconds.

Door Open Time

This section will program the amount of time an access

door can remain open before a Door Open Too Long event

is generated. After half of the Door Open Time has

expired, the reader buzzer will pulse on and off as a

warning. At the end of the Door Open Time, the buzzer

will sound steady to indicate that the door has been left

open too long. The default setting is 030 seconds. Valid

entries are from 001-255 seconds.

3.5 Zone Assignment for Access Doors

Ref # [0011XX01YY03] where XX = module #; YY = door #

Assign each “door” to a zone on the PC4010/4020. Any

zone from Zone 17 to 128 may be used (Zone 9 to 64 on

the PC4010).

You can use any zone supervision option provided by

the PC4010/4020 for PC4820 zones. The end of line

resistors used for the door inputs are 5600Ωfor the alarm

contact. If you will be using DEOL resistors, the tamper

contact is also 5600Ω.

The door’s zone must be programmed as a Standard

Delay, or an Auxiliary Delay zone (PC4010/4020

programming reference number [0100XX03], where

XX=partition number). See your PC4010/4020 v3.0

Installation Manual, section 5 “Zone Programming”.

3.6 Access Door Schedules

A date schedule can be assigned to each of the following

access door features.Adate schedule will include the start

and end times for each event, the days of the week the

schedule will be active for and any holiday groups the

event will observe.

Date Schedules 00 and 01

If date schedule 00 is programmed, the feature will be

disabled (schedule is never active). If date schedule 01 is

programmed, the feature will be always on (schedule is

always active).

For more information regarding date schedule

programming, please refer to your PC4010/4020 v3.0

Installation Manual, section 14.1 “Date Schedules”.

There are 11 access door features which can be scheduled.

They are as follows:

Postpone Arm Schedule

Ref # [0011XX01YY04] where XX = module #, YY = door #

This schedule will program at what times the auto arming

sequence can be postponed by a user presenting their

access card at the appropriate reader. Only the partitions

to which the door’s zone are assigned and that are

selected in the arm/disarm mask will be affected.

The user’s access card must also be assigned to the

appropriate partitions and have the disarming attribute

enabled for the feature to work correctly. See your

PC4010/4020 Instruction Manual for information on

programming access codes and cards.

The default date schedule is 01.

Arm Request Schedule

Ref # [0011XX01YY05] where XX = module #, YY = door #

This schedule will program when the selected partitions

may be armed by a user presenting their access card at

the appropriate reader. Only the partitions assigned to

the door zone and selected in the arm/disarm mask will

be affected.

The user’s access card must also be assigned to the

appropriate partitions and have the arming attribute

enabled in order for arming to occur. See your PC4010/

4020 Instruction Manual for information on

programming access codes and cards.

The default date schedule is 01.

Door Unlock Schedule

Ref # [0011XX01YY06] where XX = module #, YY = door #

This schedule will determine when an access door will

be unlocked. When the door is unlocked, a user will not

require an access card to open the door. The door will

remain unlocked for the duration of the schedule.

Opening the door will not cause a door forced open event.

When the partition(s) to which the door zone is assigned

are armed, the door will automatically lock at the

beginning of the exit delay. If the Door Unlock schedule

becomes active while the partition(s) are armed, the door

will not unlock. However, if the partition is disarmed while

the door unlock schedule is active, the door will unlock,

and will remain unlocked until the scheduled end time.

NOTE: If the door is assigned to more than one

partition, the door will only lock once the last partition

to be armed has begun its exit delay.

The default date schedule is 00 (disabled).

Request To Exit (REX) Schedule

Ref # [0011XX01YY07] where XX = module #, YY = door #

This schedule controls the Unlock on REX option. When

the schedule is active, tripping a Request To Exit device

will cause the door to unlock for the programmed Door

Unlock time (see section 3.5 “Door Times”). If the

schedule is not active, a Request To Exit will not cause

the door to unlock.

The default date schedule is 01.

Second Card Schedule

Ref # [0011XX01YY08] where XX = module #, YY = door #

This schedule will determine when users with the Wait

For Privilege option enabled will require a Privileged user

to grant them access to the area. If the Second Card

Schedule is active, the following will occur:

The user with the Wait For Privilege card presents their

card first. The LED on the card reader will flash slowly

for 10 seconds. If during this time a Privileged card is

used, the door will be unlocked. Only privileged cards

are capable of allowing access to the system. If a non-

privileged card is used, the door will not be unlocked

and a log will be made to the buffer. This feature is used

for monitoring the access of users on the system.

The default date schedule is 00 (disabled).

Disarm Request Schedule

Ref # [0011XX01YY09] where XX = module #, YY = door #

This schedule will program the times when the selected

partitions may be disarmed by a user presenting their

access card at the appropriate reader. Only partitions

which have the door’s zone assigned to them, and that

are selected in the arm/disarm mask will be affected.

To disarm the partition(s), the user must present their

access card and open the door. The partition(s) will be

disarmed if the Disarm Request schedule is active. If the

user presents their card is outside of the Disarm Request

schedule time window, the door will be unlocked but

the partition(s) will not be disarmed when the door is

opened. The user must then enter their access code at a

keypad to disarm the partition(s).

NOTE: To disarm a partition or enter a partition which

is armed, the user must be assigned to the partition,

and the user’s disarm attribute must be enabled in

access code and card programming. See your PC4010/

4020 Instruction Manual for information on

programming access codes and cards.

The default date schedule is 00 (disabled).

Code Schedule

Ref # [0011XX01YY11] where XX = module #, YY = door #

When this schedule is active, the door will not unlock

until the card is presented AND a valid access code is

entered on the keypad. When the schedule is inactive,

the door will unlock when an access card is presented.

If Schedule [00] is programmed into this section, the door

will be unlocked by an access card only when the

partition(s) the door is assigned to are disarmed. When

the partitions are armed, an access code will also be

required.

NOTE: The Code Required option must be enabled in

order for this feature to work.

The default date schedule is 01.

Forced Open Schedule

Ref # [0011XX01YY12] where XX = module #, YY = door #

When this schedule is active and a door is opened without

tripping a REX device, a Door Forced Open event will be

logged to the event buffer and transmitted to central

station. When the schedule is inactive and a door is forced

open, the event will be logged, but not transmitted.

NOTE: In order for this option to work, the door must

be assigned a zone and that zone must be assigned to

one or more partitions.

The default date schedule is 00 (disabled).

Forced Open Bell Schedule

Ref # [0011XX01YY13] where XX = module #, YY = door #

When this schedule is active and a door is opened without

tripping a REX device, the partition(s) the door is assigned

to will go into alarm. The alarm will be on until the bell

cut-off time expires, or until an access code is entered to

silence the alarm.

NOTE: In order for this option to work, the door must

be assigned a zone and that zone must be assigned to

one or more partitions.

The default date schedule is 00 (disabled).

Open Too Long Schedule

Ref # [0011XX01YY14] where XX = module #, YY = door #

When the schedule is active and the assigned door is left

open past the Door Open time, an Open Too Long event

will be logged to the event buffer and transmitted. When

the schedule is inactive and the door is left open past the

Door Open time, the event will be logged but not

transmitted. The Door Open time is default set at 30

seconds but can be changed (see Section 3.4 “Door

Times”).

P r o g r a m m i n g t h e P C 4 8 2 0

NOTE: In order for this option to work, the door must

be assigned a zone and that zone must be assigned to

one or more partitions.

The default date schedule is 00 (disabled).

Open Too Long Bell Schedule

Ref # [0011XX01YY15] where XX = module #, YY = door #

When the schedule is active and the assigned door is left

open past the Door Open time, the partition(s) the door is

assigned to will go into alarm. The alarm will remain on

until the bell cut-off time expires, or until an access code is

entered to silence the alarm. The Door Open time is set at

30 seconds by default, but can be changed (see Section 3.4

“Door Times”).

NOTE: In order for this option to work, the door must

be assigned a zone and that zone must be assigned to

one or more partitions.

The default date schedule is 00 (disabled).

3.7 Access Level

Ref # [0011XX01YY10] where XX = module #, YY = door #

Access levels allow specific users to have access to areas

of the system at various times of the day. Each door can

have multiple access levels assigned to it. Each access

level will follow one date schedule.

There are 63 access levels for each door. To program access

levels, select an access level number (02-63) and then enter

the schedule number that the access level will follow.

Access cards programmed with access level 01 always

have access to all doors. Access levels 02 - 63 will be

recognized by the card reader during the windows

provided by the assigned date schedule.

Date Schedules 00 and 01

Access levels programmed with date schedule 01 will

always be recognized by the door. Access levels

programmed with date schedule 00 will never be

recognized by the door. In order to disable an access level

for a door, assign the access level to Date Schedule 00.

By default all access levels are assigned to Date Schedule

00 (disabled).

3.8 Programming Access Cards

In order for an access card to function on the PC4820 the

card must first be programmed into the PC4010/4020.

This is done through user programming (enter

[*][5][system master code] or [supervisory code]). See

your PC4010/4020 Instruction Manual for more

information on programming access codes and cards.

Diagnostics

4.1 Hardware Reset

On occasion, it may be necessary to perform a reset of the

PC4820 to factory default programming. To perform a

hardware reset of the PC4820, the following steps must

be performed:

1. Power down the PC4010/4020 by removing both AC

and battery power from the control panel.

2. Power down the PC4820 modules by removing both

AC and battery power from the units.

3. Remove all connections from the following PC4820

terminals; OUT (for OUT DOOR 1), Door (for

INPUTS DOOR 1) and AUX+.

4. On the selected PC4820, connect a short from the

terminals marked as OUT (for OUT DOOR 1) and

Door (for INPUTS DOOR 1). Next connect a 5600 ohm

resistor from the Door input to the AUX+ terminal.

5. Restore AC power to the PC4820 module(s).

6. Wait for 10 seconds then remove AC power to the

PC4820 module(s).

7. Remove the connections made in Step 4.

8. Any terminal connections removed in Step 3 can now

be reconnected.

9. Restore AC and battery power to the PC4820

module(s)

10. Restore AC and battery power to the PC4010/4020

control panel.

The PC4820 will now indicate to the PC4010/4020 that a

hardware default has been performed and the PC4010/

4020 will retransmit all programming information back

to the PC4820 modules. All keypads on the system will

beep quickly 16 times to indicate that the programmed

information has been sent to the PC4820.

Be sure to remove all connections involved in the hardware

default procedure when the hardware default has been

completed.

NOTE: When performing a hardware or software

default of the PC4010/4020 be sure to also perform a

hardware default on the PC4820. This will insure that

all unwanted programming has been removed from

the module.

4.2 Diagnostics via VTAL LED (L1)

The VTAL LED (located on the right hand side of the circuit

board) of the PC4820 is capable of providing diagnostics

information for various conditions that may appear on

the module.

• Steady flash (once per second) indicates normal

operation.

• Fast flash indicates that communication to the

PC4010/4020 has been lost (Combus fault).

• On steady (1/2 second) indicates data is being

received from an access card reader.

WARNING Please Read Carefully

Note to Installers

This warning contains vital information. As the only individual in contact with system users, it is your

responsibility to bring each item in this warning to the attention of the users of this system.

System Failures

This system has been carefully designed to be as effective as possible. There are circumstances, how-

ever, involving fire, burglary, or other types of emergencies where it may not provide protection. Any

alarm system of any type may be compromised deliberately or may fail to operate as expected for a

variety of reasons. Some but not all of these reasons may be:

■■

■Inadequate Installation

A security system must be installed properly in order to provide adequate protection. Every installation

should be evaluated by a security professional to ensure that all access points and areas are covered.

Locks and latches on windows and doors must be secure and operate as intended. Windows, doors,

walls, ceilings and other building materials must be of sufficient strength and construction to provide

the level of protection expected. A reevaluation must be done during and after any construction activity.

An evaluation by the fire and/or police department is highly recommended if this service is available.

■■

■Criminal Knowledge

This system contains security features which were known to be effective at the time of manufacture. It

is possible for persons with criminal intent to develop techniques which reduce the effectiveness of

these features. It is important that a security system be reviewed periodically to ensure that its features

remain effective and that it be updated or replaced if it is found that it does not provide the protection

expected.

■■

■Access by Intruders

Intruders may enter through an unprotected access point, circumvent a sensing device, evade detection

by moving through an area of insufficient coverage, disconnect a warning device, or interfere with or

prevent the proper operation of the system.

■■

■Power Failure

Control units, intrusion detectors, smoke detectors and many other security devices require an adequate

power supply for proper operation. If a device operates from batteries, it is possible for the batteries to fail.

Even if the batteries have not failed, they must be charged, in good condition and installed correctly. If a

device operates only by AC power, any interruption, however brief, will render that device inoperative

while it does not have power. Power interruptions of any length are often accompanied by voltage fluctua-

tions which may damage electronic equipment such as a security system. After a power interruption has

occurred, immediately conduct a complete system test to ensure that the system operates as intended.

■■

■Failure of Replaceable Batteries

This system’s wireless transmitters have been designed to provide several years of battery life under normal

conditions. The expected battery life is a function of the device environment, usage and type. Ambient

conditions such as high humidity, high or low temperatures, or large temperature fluctuations may reduce the

expected battery life. While each transmitting device has a low battery monitor which identifies when the

batteries need to be replaced, this monitor may fail to operate as expected. Regular testing and maintenance

will keep the system in good operating condition.

■■

■Compromise of Radio Frequency (Wireless) Devices

Signals may not reach the receiver under all circumstances which could include metal objects placed on or

near the radio path or deliberate jamming or other inadvertent radio signal interference.

■■

■System Users

A user may not be able to operate a panic or emergency switch possibly due to permanent or temporary

physical disability, inability to reach the device in time, or unfamiliarity with the correct operation. It is

important that all system users be trained in the correct operation of the alarm system and that they

know how to respond when the system indicates an alarm.

■■

■Smoke Detectors

Smoke detectors that are a part of this system may not properly alert occupants of a fire for a number of

reasons, some of which follow. The smoke detectors may have been improperly installed or positioned.

Smoke may not be able to reach the smoke detectors, such as when the fire is in a chimney, walls or roofs,

or on the other side of closed doors. Smoke detectors may not detect smoke from fires on another level of

the residence or building.

Every fire is different in the amount of smoke produced and the rate of burning. Smoke detectors cannot

sense all types of fires equally well. Smoke detectors may not provide timely warning of fires caused by

carelessness or safety hazards such as smoking in bed, violent explosions, escaping gas, improper storage

of flammable materials, overloaded electrical circuits, children playing with matches or arson.

Even if the smoke detector operates as intended, there may be circumstances when there is insufficient

warning to allow all occupants to escape in time to avoid injury or death.

■■

■Motion Detectors

Motion detectors can only detect motion within the designated areas as shown in their respective installa-

tion instructions. They cannot discriminate between intruders and intended occupants. Motion detectors

do not provide volumetric area protection. They have multiple beams of detection and motion can only be

detected in unobstructed areas covered by these beams. They cannot detect motion which occurs behind

walls, ceilings, floor, closed doors, glass partitions, glass doors or windows. Any type of tampering whether

intentional or unintentional such as masking, painting, or spraying of any material on the lenses, mirrors,

windows or any other part of the detection system will impair its proper operation.

Passive infrared motion detectors operate by sensing changes in temperature. However their effective-

ness can be reduced when the ambient temperature rises near or above body temperature or if there are

intentional or unintentional sources of heat in or near the detection area. Some of these heat sources

could be heaters, radiators, stoves, barbeques, fireplaces, sunlight, steam vents, lighting and so on.

■■

■Warning Devices

Warning devices such as sirens, bells, horns, or strobes may not warn people or waken someone sleeping if

there is an intervening wall or door. If warning devices are located on a different level of the residence or

premise, then it is less likely that the occupants will be alerted or awakened. Audible warning devices may be

interfered with by other noise sources such as stereos, radios, televisions, air conditioners or other appliances,

or passing traffic. Audible warning devices, however loud, may not be heard by a hearing-impaired person.

■■

■Telephone Lines

If telephone lines are used to transmit alarms, they may be out of service or busy for certain periods of

time. Also an intruder may cut the telephone line or defeat its operation by more sophisticated means

which may be difficult to detect.

■■

■Insufficient Time

There may be circumstances when the system will operate as intended, yet the occupants will not be

protected from the emergency due to their inability to respond to the warnings in a timely manner. If the

system is monitored, the response may not occur in time to protect the occupants or their belongings.

■■

■Component Failure

Although every effort has been made to make this system as reliable as possible, the system may fail to

function as intended due to the failure of a component.

■■

■Inadequate Testing

Most problems that would prevent an alarm system from operating as intended can be found by regular

testing and maintenance. The complete system should be tested weekly and immediately after a break-

in, an attempted break-in, a fire, a storm, an earthquake, an accident, or any kind of construction

activity inside or outside the premises. The testing should include all sensing devices, keypads, con-

soles, alarm indicating devices and any other operational devices that are part of the system.

■■

■Security and Insurance

Regardless of its capabilities, an alarm system is not a substitute for property or life insurance. An alarm

system also is not a substitute for property owners, renters, or other occupants to act prudently to prevent

or minimize the harmful effects of an emergency situation.
