5. System Faults

Your system may light the Fault LED and start an internal alarm to indicate
that it has detected a fault. (An internal alarm is the keypad and internal
sounders active, but the external sounder (bell) and strobe quiet.) The display
will give a two letter code to indicate what type of fault has occurred. The
table below shows the more common faults that can happen.
