A cover tamper is a safety feature that provides a trouble signal when the system has been opened. To clear the cover tamper simply open and close the device making sure the cover is reassembled correctly.
1. Remove the screw on top of the keypad and pry open slots with a flat head screwdriver.
2. Gently pull the front cover down then close the cover again and tighten the screw
(If the screw is lost replace with a Phillips oval head matching screw 4-40 X 3/8" SS)
