What Does Fault Mean

A malfunction is discovered in the system, an open is detected in a fire zone, or a fault

in a day/night burglary zone is discovered during a disarmed period. Accompanied by a

display of the zone number in trouble. The fault condition may also be caused by some

change in the environment that prevents the built-in receiver from receiving signals from

a particular wireless sensor.

After correcting the problem, the display can be cleared by entering the security code plus

the OFF key twice.
