Alarm Input
Question: Which systems will trigger alarm conditions?
Answer:

The ViewPro™ Observation system will accept standard NO (N.O. and N.C. color quad only) contact closures to trigger alarm conditions. The alarm device may be a magnetic door contact or the output of an external motion detector. The alarm trigger is applied to the system using the 6-pin RJ11E "interphone" or "accessory" input located on the rear of each ViewPro™ camera. The alarm input is connected to the camera using the 60-foot, 2-wire, A-SC20 interface cable. Refer to the following connection diagram for proper connection.
