Section 2 - Wiring; Wiring Guidelines; Power; Wire Runs - DKS 1837 Series Installation & Owner's Manual

Prior to installing wiring to 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 wiring of the telephone entry 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 telephone entry system is 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 the
user cannot come into contact with the gate or gate operator when using this entry system. 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.
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 enclosure by touching
a proper ground device.

2.1 Wiring Guidelines

2.1.1 Power

Use only the two (2) supplied transformers (or UL listed equivalent) to power the telephone entry and access control system
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 telephone entry
system.
Two 16.5 VAC, 20 VA for
1833, 1834 and 1835.
One 16.5 VAC, 20 VA and
One 16.5 VAC, 40 VA for 1837.
"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 system power and one for the auxiliary terminal power.

2.1.2 Wire Runs

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.
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.

SECTION 2 - WIRING

Wire polarity does not matter
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!
Power wires are susceptible to noise and hum pickup; therefore
it is preferable that you keep power wire runs as short as possible.
