Section 21 System Operation
21-5
A display of BAT (on fixed-word keypads) or SYSTEM LO BAT (on alpha keypads)
with no zone number indicates that the system's main standby battery is weak.
A display of "BAT" (on fixed-word keypads) or LO BAT (on alpha keypads) with a
zone number and a once per minute "beeping" at the keypad indicates that a low-
battery condition exists in the wireless sensor displayed (zone "00" indicates a wireless
keypad). If the battery is not replaced within 30 days, a CHECK display may occur.
Bell Failure (CHECK 70) Wiring loop to external sounder is either open or shorted.
RCVR Jam (CHECK 90) RF jam detected.
NOTE: Some wireless sensors contain a nonreplaceable long-life battery that requires
replacement of the entire unit at the end of battery life
(e.g., 5802, 5802CP).
Power Failure
If there is no keypad display at all, and the POWER indicator (if present) is not lit,
operating power for the system has stopped and the system is inoperative.
NOTE: The control panel will power-up in its previous state (armed or disarmed) after a
complete power failure, but will not retain any memory of bypasses.
If the message AC LOSS (on alpha keypads) or NO AC (on fixed-word keypads) is
displayed, and the POWER indicator (if present) is off, the keypad is operating on battery
power only.
NOTE: There is a random delay of up to 30 minutes before the system will report an AC
failure to the central station. The keypad response is about 6 seconds. The
Restore Report has a random delay of up to 30 minutes (if the AC Failure Report
was sent).
If the battery standby capacity is used up during a prolonged AC power outage, the
control's auxiliary power will shut down to minimize deep discharge of the battery.
Other Displays (fixed-word displays are in parentheses)
Busy-Standby (
dI
). If this remains displayed for more than 1 minute, the system is
disabled.
Modem Comm (CC) The system is in communication with the central station for change of
function or status verification.
Comm. Failure (FC) A communication failure has occurred.
Open Circuit (OC) The keypad is not receiving signals from the control and sees an open
circuit.
Long Rng Trbl (bF) Backup LRR communication failure.
