1.2 Wiring
The wiring of this device is an extremely important and integral part of the access control system. It is
very important that proper wire is used for power and control lines, and that the system is properly
grounded.
The digital keypad can operate on 10-16.5 volt AC power, or 12-24 DC power.
Do not run power wiring greater than 200 feet.
Do not power electric strikes or magnetic locks from the power supply. Strikes, locks and
other devices must be powered from their own power source.
It is preferable to keep power wiring as short as possible. A low voltage surge suppresser
(P/N 1878-010) is recommended.
Be sure to properly ground the digital keypad. Attach a separate 12 AWG wire to the ground
lug on the circuit board. Attach the other end of this wire to a good earth ground. This can
be a properly grounded metal conduit, a cold water pipe, or a grounding rod driven at least 10
feet into the soil. A gooseneck post anchored or mounted on concrete does not make a good
ground.
Avoid any splices in wiring. If a splice is made, it must be soldered and sealed in a watertight
junction box.
Relay contacts are rated for 30 Volt, 1 Amp.
A switch closure across terminals 1 and 12 will activate relay 1 for its programmed strike time.
Use U.L. listed wire with an insulation rating of 600 volts.
If a secondary keypad (p/n 1506-081) is connected, refer to the instruction sheet included
with the secondary keypad assembly.
Maximum distance for secondary keypad wiring is 200 feet using an 8 conductor 22 AWG
shielded cable.
The secondary keypad does not have any relays. It only provides a method to access the
entry codes from a second location. Typically, the secondary keypad is used when both
entry and exit control are required through a common door or gate.
