Recommended Wiring:
- 18/2 for all 12VDC, Relay, and Bypass wiring
- 18/2 OAS (shielded) for intercoms
- 18/2 for camera power if installed in keypad (do not piggyback power from keypad, this VOIDS THE WARRANTY)
- 18/2 for Door Strike or Mag Lock (do not piggyback power from keypad, this VOIDS THE WARRANTY)
- CAT-5 or CAT-6 (300’ distance limitation)
- RG-59 (keypad cameras under 700ft)
Wiring Requirements
- 12 VDC runs should be no longer than 200ft (please note that the keypad needs a minimum of 11.70 volts DC to operate correctly)
- Earth Ground wiring – grounding is most effective at short distances as electricity travels to the point of least resistance. All grounding locations should be 6’ or less from the keypad. (12 AWG stranded works best for flexibility when closing the keypad in housing)
- Splices made on 18/2 should always be done with wire nuts or using a suitable termination/splice block.
- Any splices made in underground junction boxes or in an area where water or other foreign materials could short the wires, they must have a wire nut (or similar connector) filled with silicone or like material.
- BNC coax crimps should be used at all terminations and splice points when working with video coax.
- BNC couplers should be used at all splice locations when working with video coax (it is recommended that you wrap the splice with electrical tape to avoid grounding the video signal)
Conduit Requirements
- A minimum of one ¾” to 1” conduit is needed from the office management area to the gate operator, junction box, or Christie™ box.
- A minimum of one ¾” conduit to each keypad stubbed up approximately a foot above grade is needed.
- A minimum of one ¾” conduit is needed from the junction box or Christie box to the gate motor for the relay control wires if your layout does not allow stubbing up next to the gate motor.
Note: If the keypads have cameras, it is necessary to use 1” conduit or larger for the main run from the office
Here are some additional installation tips.
Have wire pulled and ready to go the day you call
Have keypad inside the office connected to the network (make sure IT has the port on the switch open and unrestricted)
Have the IT company on standby because managed switches require administration privileges
We will install gate software and verify the keypad is communicating in the office before it goes out into service
Final check will be done after the keypad is installed

Do NOT use 120 conduit for low voltage communications cable
