This unit makes virtually any keypad a demo with a simple four wire connector. The keypad demo allows you to fault both an exit/entry zone and perimeter zone through the use of toggle switches to simulate the opening and closing of doors, windows or other types of protection devices. There is an on/off switch to provide power to the demo and the unit itself is powered with two user-replaceable 9-volt DC batteries. Basic keypad operations include: user-code arming and disarming, quick arming, bypassing, forced bypass, etc.
