CONTROLLER ADDRESS DIP SWITCHES
Each individual DIP switch represents a pre-defined value (as printed on PCB beside the address block),
which added together forms the device address. LINKnet device addresses must be between 1 and 12 for the
device to communicate with its’ master device. Each LINKnet device must have a unique device address in
this range.
M
OUNTING
The Access Door Module is designed for quick and easy mounting in a number of locations. Normally this
should be within a secured enclosure.
A tamper switch should always be wired to the Access Door Module, indicating when someone enters the
enclosure and tampers with the Access Door Module. Any standard switch that will mount inside the
enclosure can be used. The tamper switch can be wired so that the circuit is monitored using an EOL circuit
(see Input Wiring below for details).

Access Door Module ADM-2W704 (Rev 1.3) Installation & Application Guide
Page 8 of 26 Access Door Module
POWER WIRING
All power wiring must be completed by a licensed electrician and conform to the National Electrical Code,
ANSI/NFPA 70, and local codes and regulations.
The Access Door Module must be powered by the UL listed, 24VAC, 50/60 Hz Basic Electric transformer,
Model 7511CBDH, or equivalent. Connect low voltage power (24VAC) from the UL listed transformer to the
AC power terminals, marked as 24~.
•The Access Door Module needs to use its own dedicated transformer as its 24 VAC
power source. You may not connect several controllers to the same transformer.
•Use 14 AWG minimum for wiring the AC in (i.e.120VAC) side of the UL listed
transformer, per NEC requirements.
•Keep adequate spacings between battery, power limited field wiring and AC in.
Suggest using UL recognized cable ties. Minimum .25” separation must be provided.
•Use proper strain relief for any flexible wiring.
•Use bushings on rough surfaces to protect cabling from abrasion.
•Do not wire power cord behind electrical enclosure.
•All terminals are acceptable for Class 2 Circuit connections only
•Use copper conductors only
•Apply minimum 6.0 lb-in torque for tightening field wires into the terminal blocks
BATTERY BACKUP WIRING (NOT TO BE CONNECTED IN UL APPLICATIONS)
The Access Door Module has been designed with a battery circuit to provide the option of both battery
charging and battery backup for the controller. The battery backup supplies power to the controller, its
output devices (if power from the board), and Auxiliary power connections. Battery backup should be used
when using Magnetic Locks on any doors that you would like to keep locked when there is a power failure or
having the Access Control System be functional in the event of a power loss.
The battery charging circuit has been designed for the following battery specifications:
•7 Amp Hours
•Sealed Lead Acid battery only
•Capable of both a trickle charge and bulk charge
•Use supplied 0.25” Faston Lugs for connecting battery
Using a 7 AH Battery, the table below shows approximately how long the battery will last when fully
charged. (Not evaluated by UL)

INPUT WIRING
There are 2 input types on the Access Door Module:
•Wiegand Inputs
•Regular Contact/Resistive Inputs (supplied with 10 – 10K ¼ Watt resistors for EOL circuits)
Wiegand Inputs are for card readers, keypads, biometric devices, etc, using the standard Wiegand Input signals
on WD0 and WD1. See table below for input assignment and numbering.
Regular inputs are resistive 10K Ohm pull-up inputs and are used for Door Contact, Request to Exit, etc.
Inputs follow the same general wiring connection diagrams as other Delta products, with the exception that you
can use EOL circuits to monitor the input wiring for open or short circuits. When EOL circuits are in place the
input must be created as a Multistate Input (MI) with the proper Multistate Input Configuration (MIC) for the
scale range. For details on the MIC scale range refer to the Technical Reference Manual. See below for
wiring details when using EOL circuits.
The Request to Exit input is configured based on the type of Door Lock that you are going to use. Placing a
jumper in the proper terminals on the board configures the Request to Exit input. Product is shipped
configured as a Fail Secure door. See diagram below.
The tamper switch input is connected to a standard single contact switch such as the Locknetics Security
Model 7766 (either the N.O. or N.C. action can be set-up in the input object) to monitor intrusion of the Access
Door Module’s enclosure.

Wiegand Device Wiring (examples using HID and AWID card readers)
Wiegand Device wiring details are shown below. The +5 VDC power for card readers is from a switched
power supply and is used with Wiegand magnetic stripe readers, etc. It is recommended, when using proximity
card readers, that you should use the +12 VDC power supplied by the board for maximum read distance. The
Access Door Module +12 VDC is a linear power supply (which is required by most proximity card reader
manufacturers).
You should follow the wiring and wire type specifications of the card reader manufacturer that you are using.
Below is the typical wire type and distance specified by most card reader manufacturers; these are the
specifications for the card readers supplied by Delta Controls Inc. Card readers should always be grounded
properly to ensure proper operation (refer to the manufacturers installation data).

Request to Exit Input (Not Evaluated by UL)
The Request to Exit input has 2 components; the first is the Request to Exit Status that is monitored by
software, to give the operator the status of the button. The second component is the contact on the Request to
Exit button that interrupts the Door Lock signal to allow egress. The Request to Exit push button must have
both an N.O. contact and an N.C. contact to retrieve the status and to interrupt the Door Lock for egress. The
table and diagram below show how the Request to Exit should be configured and wired for the Door Lock type
chosen.
When using a Type 3 or Type 4 EOL Circuit and a Request to Exit button that has a single pole switch, make
sure that the 10K Ohm resistor is on the input leg of the circuit, not the ground side of the circuit, or the Door
Lock and/or Request to Exit status may not work properly, as shown below. Optional EOL Circuit resistors
are shown for EOL Circuit Types 3 and 4.
RTE Configuration and Wiring
The product is shipped configured for Fail Secure doors.

Fail Secure N.C. N.O. 1-2

Delta Controls
Access Door Module Page 15 of 26
If no RTE is being used, you must configure the circuit. If the Door Lock is configured as fail-safe, a jumper
needs to be put in place of the RTE Contact. The diagram below shows how the RTE circuit is configured
when not using an RTE device.
Note: Fail secure only allowed where NFPA 101or local authorities allow.

EOL Circuits
Any of the inputs, other than the Wiegand Inputs, can be wired to be monitored/supervised circuits able to
detect problems or tampering with wiring. The 4 types, Type 1,2,3, and 4, of monitored circuits that Delta
Controls supports are described with the diagrams below. Each EOL circuit is based on 10K Ohm (±5%)
resistors. EOL resistors should be installed at the end of the line (at the device), not at the Access Door Module
(controller). Placing an EOL at the Access Door Module renders the circuit unmonitored, as it will only
monitor to the point of the controller connection.
Delta Controls recommends using EOL Types 3 & 4 if input wiring is to be monitored as they
provided the most information regarding the condition of the input circuit (wiring).
Scale Ranges (MIC objects) have been provided with the release CD-ROM, that should be used for these types
of inputs. You must use the MIC Objects provided as the software controlling Door Locks for the values in
pre-defined spots.

Type 1 EOL Circuit (Normally Closed Contact)
Used to monitor a Normally Closed contact, this EOL supervised circuit will give you a Trouble signal, in
addition to the Normal and Alarm signals, to let you know if the circuit has been shorted (contact bypassed). It
does not give Trouble indication of an Open circuit (wires cut), but it will cause an alarm condition.
Type 2 EOL Circuit (Normally Open Contact)
This EOL Circuit is used to monitor/supervise a Normally Open contact, to indicate Trouble when there is an
Open Circuit (wires cut). A short circuit (contact bypassed) will not indicate Trouble, but will generate an
Alarm condition.

OUTPUT WIRING
The Outputs on the Access Door Module, like the inputs, are not general outputs. They typically have specific
operations. There is an auxiliary output for each door on the board that gives you an SPDT relay output.
Outputs on the Access Door Module follow the same general wiring connection diagrams as other Delta
products. Refer to separate documentation for additional details regarding this wiring.

Door Lock Wiring Detail
The Door Lock output is wired straight back to the Access Door Module as shown below. The Access Door
Module supplies +12VDC @ 350 mA maximum for powering the Door Lock. Therefore only +12VDC Door
Locks can be wired directly to the board, as shown below. If the Door Lock draws more than 350mA, then the
Door Lock should be wired as shown in the following diagram.
If a voltage other than +12VDC or an AC voltage is needed for the Door Lock, a DC Relay and a separate
power supply to control the Door Lock is needed, see wiring detail below. This wiring configuration can also
be used when the Door Lock draws more than 500mA.
WARNING
When a Door Lock is connected this way, the Door Lock will not be battery backed-up by the
board, but needs to be battery backed-up from it’s own source.
