System Operation
Trouble Conditions
The word "FAULT" on the keypad's display, accompanied by a rapid "beeping" at the keypad, indicates that
there is a trouble condition in the system. Pressing any key can silence the audible warning sound. Instruct
users to call for service immediately upon seeing any of the following messages.
"Fault" and "Battery" Displays
• "FAULT" and one or more zone numbers indicates that a problem exists with the displayed zone(s)
and requires attention. After correcting the problem, the display can be cleared by entering the security
code plus the OFF key twice.
• 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.
• "LOW BAT" with no zone number indicates that the system's backup battery is weak.
• "LOW BAT" with a zone number and a once-per-45 seconds "beeping" at the keypad indicates that a
low battery condition exists in the wireless sensor displayed (zone "00" indicates a wireless button/keypad).
If the battery is not replaced within 30 days, a "FAULT" display may occur.
Power Failure
• If there is no display at all, and both indicators are not lit, operating power for the system has
stopped and the system is inoperative.
• If the display is lit and the AC display is off, the system is operating on battery power only.
• During an AC power loss, the backlighting will turn off and the indicators will flicker slightly to
minimize deep discharge of the battery.
Other Displays
dI = Busy-Standby: Displayed upon power-up. After approximately 1 minute* the green "READY" LED
should light. If the "dI" remains displayed for more than 1 minute, the system is disabled.
*To bypass the 1-minute delay, press [#] + [0]. Important: Do not try to bypass 1minute delay before "dI" is
displayed!
CC = Modem Comm: The system is communicating with the central station for change of function or
status verification.
FC = Comm. Failure: A communication failure has occurred. This message clears only when the system
is subsequently armed.
90 = RF Jam: The system has detected an RF jamming condition or excessive interference.
