DOC - Canada
The Canadian Department of Communications label identifies certified equipment. This certification means that the equipment
meets certain telecommunications network protective, operational, and safety requirements. The Department does not guaran-
tee the equipment will operate to the users satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecom-
munications company. The equipment must also be installed using an acceptable means of connection. The customer should be
aware that compliance with the above conditions may not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any
repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications
company cause to request the user to disconnect the equipment.
Users should ensure, for their own protection, that the electrical ground connections of the power utility, telephone lines, and
internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural
areas.
CAUTION: Users should not attempt to make such connections themselves, but should contact the appropriate electric inspec-
tion authority, or electrician, as appropriate.
DOC Registration Number: 1736 4507 A
Notice:
The Load Number (LN) assigned to each terminal device denotes the percentage of the total load to be connected to a telephone
loop which is used by the device, to prevent overloading. The termination on a loop may consist of any combination of devices
subject only to the requirement that the sum of the load numbers of all the devices does not exceed 100.
Notice:
DoorKing does not provide a power transformer on units sold into Canada. Use only transformers that are CSA listed to power
the telephone entry system. The model 1812 Access Plus requires a 16.5-volt, 20 VA transformer.
Important Notices

1812-162-V-5-16 7
1. If the clear floor space allows only forward approach to the system, the maximum high forward reach allowed is
48inches above grade to the top of the keypad.
2. If the high forward reach to the system is over an obstruction of greater than 20 inches but less than 25 inches,
the maximum high forward reach allowed is 44 inches above grade to the top of the keypad.
3. If the clear floor space allows parallel approach by a person in a wheelchair, the maximum high side reach shall
be 54 inches above grade to the top of the keypad.
4. If the high side reach is over an obstruction of 24 inches or less, the maximum high side reach allowed is 46
inches above grade to the top of the keypad.
•Prior to beginning the installation of the telephone entry system, we suggest that you become familiar with the
instructions, illustrations, and wiring guidelines in this manual. This will help insure that you installation is performed in
an efficient and professional manner.
•The proper installation of the telephone entry panel is an extremely important and integral part of the overall access
control system. Check all local building ordinances and building codes prior to installing this system. Be sure your
installation is in compliance with local codes.
•When used to control a door or pedestrian gate, try to locate the telephone entry system as near as possible to the entry
point. The unit should be mounted on a rigid wall to prevent excessive shock and vibration from closing doors or gates.
Continuous vibration and shock from slamming doors or spring-loaded pedestrian gates will damage the circuit board.
Under no circumstances should the unit be mounted directly to a moving door or gate.
• ADA mounting requirements for door control. The requirements below apply only when the telephone entry system is
being used to control entry through a public door only. If this system is used to control entry through a vehicular gate or
private entrance, the dimensions noted below do not apply.
•When used to control a vehicular gate with an automatic gate operator, the telephone entry system must be
mounted a minimum of ten (10) feet away from the gate and gate operator, or in such a way that a person cannot
operate the entry system and/or touch the gate or gate operator at the same time.
•Be sure that the system is installed so that it is not directly in the traffic lane. Goose neck mounting post and kiosks
work well for these type systems. When planning where to locate the system, take into consideration traffic lane layouts,
turn around lanes for rejected access, conduit runs, power availability, etc.
•Environmental factors must also be taken into account. Surface mount units are designed for direct outdoor
installations, however it is preferable to protect them from direct exposure to driven rain or snow whenever possible.
Flush mount units must be protected from direct exposure to the elements.
•This telephone entry system contains a number of static sensitive components that can be damaged or destroyed by
static discharges during installation or use. Discharge any static prior to removing the circuit board from the lobby panel
by touching a proper ground device.
•Instruct the end user to read and follow these instructions. Instruct the end user to never let children play with or
operate any access control device. This Owner’s Manual is the property of the end user and must be left with them
when installation is complete.

Different Mounting Configurations of the 1812 Access Plus Models
Surface and Wall mount models can be mounted directly to a wall, pilaster or post mounted using a DoorKing mounting post
(there are several different styles available). The flush mount model is designed to be mounted into a pilaster, wall or kiosk. In
any case, be sure it is securely mounted and is not subject to continuous vibration from closing doors or gates.
Use existing 4 holes in cabinet box to
bolt the surface or wall mount models
on a DoorKing mounting post. Use
the hardware that is supplied with the
mounting post.
Note: A gooseneck mounting
post anchored in concrete
does not make a good ground.
Mount on a Mounting Post
IMPORTANT Choose
how your 1812 will
function (Telephone
Mode or Intercom
Mode) on pages 14
thru 18and run the
indicated wires to the
cabinet. Also route
RS-485 and/or network
connection wires to the
cabinet if they are to be
used. Run ALL wires
that will be needed
during the cabinet
installation.
Use the 4 existing holes in the
cabinet box. Run conduit inside or
outside of wall or pilaster if desired.
Use appropriate hardware to mount
the cabinet (Not supplied). Be sure
that the mounting hardware does not
protrude into the cabinet where it
could cause a short.

Mount rough-in box into the pilaster, wall or kiosk. Run conduit inside wall into bottom of rough-in box if desired.
Use appropriate hardware (Not supplied) to secure the rough-in box in place.
Remove the 18-pin main terminal connector, and if necessary,
the 8-pin RS-485 connector from the control board by gently pulling
them straight up. This will make wiring to the control board easier. Note
the orientation and numbering sequence of each connector to correctly
wire it.
Re-install control board by carefully routing all incoming wires around it
and secure it in place with 4 screws. Re-connect the keypad plug (cable
points down) and door accessories plug (red wire goes to the left) to the
control board.
Connect all wires to the 18-pin connector and to the 8-pin
connector if needed (See pages 19 and 20). Gently
re-connect them back on the control board. DO NOT
APPLY POWER to the 1812 at this time.

with the enclosed equipment: to provide a degree of protection against falling dirt, rain, sleet,
snow, windblown dust, splashing water, and that will be undamaged by the external formation of ice
on the enclosure.
Use only twisted pair telephone wire that is rated for direct underground burial.
DO NOT use wire that is intended for indoor applications. Recommend Cat5e
Gel Filled (flooded) UV Resistant Direct Burial Cable in conduit. DO NOT run
telephone wires and high voltage wires in the same conduit. It is recommended
to run all necessary wires to the by-pass board in a “dedicated” telephone wire
conduit. Check the phone wire chart on next page for wire size and distances.
By-pass board MUST be
properly grounded.

1.2 Install By-Pass Board for “Telephone Mode” Configurations
The 1812’s by-pass board provides a method to by-pass the 1812 and route the incoming telephone line directly to the
homeowner’s phone. The By-Pass board IS NOT optional when using an incoming telephone line or internet (Telephone
Mode) – it must be installed as part of the 1812 system. All telephone wires for the 1812 must pass through the by-pass
board. Wire the by-pass board either for a “Single 1812 - telephone mode” pages 14 - 15 or “Multiple 1812s - telephone mode”
page 16.
Mount the by-pass board in a location that is easily accessible by the homeowner. In case of 1812 trouble or maintenance, the
homeowner will use the by-pass switch on the board to route the incoming telephone line directly to their home phone. If the
by-pass board is installed outdoors, it must be installed in a NEMA Type 4 enclosure (not supplied) to protect the board from
direct exposure to landscape sprinklers, rain, snow and other elements.

Note: Do not run telephone wires and high voltage power
wires in the same conduit. Separate the high voltage
conduit and the telephone conduit by at least 18inches to
prevent any electrical field interference that could occur.
“Tip” and “Ring” Definition. Common terms in the telephone service industry referring to the two wires or sides of
an ordinary telephone line. Tip is the ground side (positive) and Ring is the battery (negative) side of a phone circuit. The
ground side is common with the central office of the telephone company (telco); the battery side carries -48volts of DC voltage
when in an “Idle” or “On Hook” state.
Phone Line Polarity. Tip and ring reversal is mostly immaterial, except for special circuits including DID (Direct Inward
Dialing) trunks, T-1 lines, and ground start lines where the field side (“terminal”) equipment (a company's PBX switch, for
example) can only function correctly with correct tip and ring polarity.
Wire Type. It is extremely important to use the correct type of wire in telephone applications. Since the 1812 requires
phone lines to be run outdoors or in an underground environment, we recommend that you use only wire that is rated for
direct underground burial. For example, use Cat5e Gel Filled (flooded) UV Resistant Direct Burial Cable run in conduit for
your 1812 phone line requirements. Do not use thinly insulated brown-jacketed telephone wire (the type found in the walls of a
house) for outdoor or underground phone line wiring. Using improper wire can cause noise and hum on the phone line. Be
sure that phone wire pairs are twisted.
Wire Size and Distance. Phone lines can be run up to 3600 feet, provided that the proper wire size is used.
1.3 Telephone Line Wire
Be sure to observe electrical safety when working with phone lines. Phone lines carry electricity and the ring voltage can deliver
a substantial jolt. The best policy is to disconnect the house phone from the phone company Network Interface Device (also
known as ‘Demarcation Device’) before working on the wiring.
In most residential homes, the phone cable contains four wires; green, red, black, yellow. The green and red are twisted to make
one pair and the black and yellow are twisted to make another pair (This allowed for the addition of a second phone line since
telephones use only two wires). Most phone lines installed in the U.S. in the second half of the 20th Century have this type of
wire. This type of wire is now obsolete. All new telephone projects are using Cat5 wire. If you have Cat5 wiring in your home,
the conversion is simple:
The convention for Cat5 wire is as follows:
•Colored pairs match; e.g., WHITE/blue mark (Tip +) wire goes
with BLUE/white mark (Ring -) wire for one phone line, etc.
•The pairs are used in the order pictured: for the first line, you
use BLUE, for the second line you use ORANGE, etc.
•An easy way to remember this is that the colors run from the
sky to the earth. BLUE sky comes first; ORANGE sunset second;
GREEN grass third; BROWN earth last.

1.4 16.5 VAC Power Wiring ONLY!
The 1812 Access Plus operates ONLY on 16.5 VAC. DO NOT power the 1812 with 24 volt AC power. Use the supplied power
transformer, 16 VAC, 20 VA (or U.L. listed equivalent) to power the telephone entry system. DO NOT power any other devices
(electric strikes, magnetic locks, etc.) from the 1812’s power transformer. See table below for wire run distances.
Power Interruption Note: The Time
and Date calendar chip (Section 2,
2.7.1) in the 1812 Access Plus will
keep time for approximately 48hours
if power to the system is lost or
removed. If power is off longer than
this, the Time and Date will need to
be reprogrammed into the system.
All other specific programming that
has been done will remain intact after
power has been restored.
DoorKing offers a 12 volt .8 amp
hour gel cell battery that can
connect to the main terminals 9 and
10 to provide back-up power during
power interruptions.

CAUTION
DO NOT power the 1812 from a 24-Volt
source (Such as a gate operator).
Damage will occur to the 1812 that is
NOT covered under DoorKing’s warranty.
Proper Grounding and the use of surge suppressors can significantly reduce the chance of component failure because of static
charges or surges. To be effective, ground connections should be made with a minimum 12 AWG wire to a ground point within
10 feet of the device being protected. The ground point can be at an electrical panel, a metallic cold water pipe that runs in the
earth or a grounding rod driven at least 10 feet into the soil. A gooseneck mounting post anchored in concrete does NOT make
a good ground.
Telephone Line Surge Suppressor
It is highly recommended that telephone line surge
suppressor (DoorKing P/N 1877-010) be installed
to help protect the system from phone line power
surges. Surge suppressor must be positioned 3 ft
or less from the ground source, 12 AWG min.
Low Voltage Surge Suppressor
It is highly recommended that a low voltage surge
suppressor (DoorKing P/N 1878-010) be installed to
help protect the telephone entry system from power
surges. Surge suppressor must be positioned 3 ft or
less from the ground source, 12 AWG min.

Connect to Incoming Telephone
Company’s Phone Line
Locate the telephone company demarcation device.
IMPORTANT Identify the wires that connect to the
homeowner’s telephone. Disconnect these 2 wires from
the demarcation device and connect them to terminals
#7 and #8HOME on the by-pass board.
Connect a new twisted-pair telephone wire to the
telephone company demarcation device where the 2
wires were just removed from. Connect the other end of
the new twisted-pair wire to CENTRAL OFFICE terminals
#1 and #2 on the by-pass board (Unless using a surge
suppressor, then wire to surge board first).
Place the by-pass switch in the “By-Pass” position until
the 1812 installation is complete. Test the homeowner’s
telephone. It should have a dial tone while the switch is
in the “By-Pass” position. See page 11.
Check Polarity of
Telephone Line
Check for polarity on the
incoming telephone line to each
board and maintain polarity
throughout the telephone line.
One potential problem checked
when a malfunction occurs in a
telephone entry system is to
see if the telephone line has
been wired to each board with
the correct polarity.
Test Example: By-pass board’s
CENTRAL OFFICE terminals #1
and #2. Terminal #2 must be
positive (Tip +) with respect to
terminal #1 (Ring -). Set a VOM
meter to measure DC volts.
Place the positive lead on
terminal #2 and the negative
lead on terminal #1. If the
meter shows a positive voltage
- OK. If the meter shows a
negative voltage (needle moves
off scale to the left), reverse the
wires on terminals #1 and #2.

The 1812 Access Plus operates ONLY
on 16.5 VAC. DO NOT power the 1812
with 24 Volt transformer or source
voltage. Use the supplied power
transformer, 16.5 VAC, 20 VA (or UL
listed equivalent) to power the
telephone entry system. DO NOT power
any other devices (electric strikes,
magnetic locks, additional 1812s etc.)
from the 1812’s power transformer.

acceptable grounding sources.
Low Voltage Surge Suppressor
DoorKing Surge Suppressor P/N 1878-010 (or
equivalent) is optional but highly recommended.
For best protection, surge suppressor ground wire
MUST be 3-ft. or less in length. Use minimum 12 AWG
wire. Refer to instruction sheet included with surge
board for complete information.
Connect to Homeowner’s Telephone
When connecting directly to a single telephone or an
un-used C.O. port on a PBX or KSU system, use the
PHONE OUT terminals only in the 1812. It must be
programmed for INTERCOM mode using this
configuration.
When the 1812 is programmed for intercom mode, it
provides the constant source of DC voltage necessary
for communication. The intercom mode also
disconnects the “PHONE IN” terminals (1 and 2)
since they are not used.
Be sure that the 1812 is programmed in the intercom
mode.

Check Polarity of Telephone Line
Check for polarity on the incoming telephone line to
each 1812 board and maintain polarity throughout
the telephone line to the homeowner’s phone. One
potential problem checked when a malfunction
occurs in a telephone entry system is to see if the
telephone line has been wired to each board with
the correct polarity.
Test Example: 1st 1812 board’s PHONE IN
terminals #1 and #2. Terminal #2 must be positive
(Tip +) with respect to terminal #1 (Ring -). Set a
VOM meter to measure DC volts. Place the positive
lead on terminal #2 and the negative lead on
terminal #1. If the meter shows a positive voltage
- OK. If the meter shows a negative voltage (needle
moves off scale to the left), reverse the wires on
terminals #1 and #2.
