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.
