Relay Output Wiring Notes
• Install the door strike or auxiliary output device per the vendor’s instructions.
• Use shielded, twisted-pair cabling to connect the circuit to the Security Controller. Maximum cable distance is 2000 feet
(610m)
• Wire the door strike or auxiliary output device to the appropriate relay output on the Security Controller and to the power
supply used to power the strike or device. Each relay output on the Security Controller has a common terminal (C), and
normally open (NO) and normally closed (NC) terminal.
• At the Security Controller, ground shield wires to the designated grounding point at the enclosure. See Fig. 5 on page 13.
