SECTION 2 - WIRING
Be sure that you use proper wire that has an insulation
rated for an underground environment. All wires
should be placed in conduits. Proper pre-planning can
greatly ease the installation and wiring of this system.
Always check with the local building code to determine
the type of wire required in your municipality.
DO NOT run high voltage (115 V) power lines and low voltage/communication lines in the same conduit. These should be in
separate conduits at least six (6) inches apart. Be sure that all phone line wiring is twisted and completely isolated from ground.
Prior to installing wiring to the 1838, 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.
Wiring the access controller panel is an extremely important and integral part of the overall access control system. Use proper
wire for the communication line, power wires, and be sure that the system is properly grounded. Check all local building
ordinances and building codes prior to installing this system. Be sure your installation is in compliance with local codes.
Telcom Access Standards. It is not permissible for customers to use the telcom network lead-in cable to provide the intercom
function between the gate and the house. New Zealand Customers: All door and gate entry systems wiring must comply with
PTC106: March 2008, Section 9.
WARNING If this access controller is used to control a vehicular gate with an automatic gate operator, the access control-
ler must be mounted a minimum of six (6) feet away from the gate and gate operator, or in such a way that the user cannot
come into contact with the gate or gate operator when using this controller. If this unit has been installed closer to the
automated vehicular gate, do not proceed with any wiring until the unit has been moved and re-installed so that it is in
compliance with these instructions.
The 1838 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 enclosure by touching a proper ground
device.
Use only the two (2) supplied transformers (or UL listed equivalent) to power the access controller and any 26, 30 and 31 Bit
wiegand input devices that use 16.5 VAC, 20 VA. DO NOT power any other devices (expansion boards, electric strikes,
magnetic locks etc.) from these power transformers.
Note: Transformers are not supplied on units sold outside the United States. An Inherently Protected Transformer must be used
to power this device. Use only transformers that are listed by a recognized testing laboratory to power the access controller.
Wiegand wire runs are 500-feet maximum. Use
6-conductor stranded wire with overall shield. 18, 20,
22 or 24 gauge is sufficient for these connections.
“Optional” 12 volt .8 amp hour gel-cell batteries (DoorKing P/N 1801-008) can be installed to provide stand-by power in the
event of a power outage. Two batteries are required, one for the phone system power and one for the auxiliary terminal power.

2.1 Wiring Guidelines
2.1.1 Power
2.1.2 Wire Runs
Up to 100 feet, use 18 AWG, 600 volt insulated wire.
Up to 200 feet, use 16 AWG, 600 volt insulated wire.
The importance of proper AWG power wiring cannot be over stressed!
Wire polarity does not matter
Power wires are susceptible to noise and hum pickup; therefore
it is preferable that you keep power wire runs as short as possible.
Two 16.5 VAC, 20 VA
power transformers
MUST be installed for
the 1838 to operate.
DO NOT use ONE
power transformer to
power both power
terminals.
Do Not Connect To A Receptacle
Controlled By A Switch.
