(continued) TROUBLE CONDITIONS
3.A display of "BAT" with no zone number or beeping indicates that the main standby battery in your control is weak. If this condition persists for more than one day (with AC present), CALL FOR SERVICE.
4.A display of "BAT" with a zone number and a once per 40 seconds "beeping" at the keypad indicates that a low battery condition exists in the wireless sensor displayed. Either replace the battery yourself, or CALL FOR SERVICE. If the battery is not replaced within 30 days, a CHECK display may occur.
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. CALL FOR SERVICE IMMEDIATELY.
If the message "AC LOSS" or "NO AC" is displayed, and the POWER indicator (if present) is off, the keypad is operating on battery power only. If only some lights are out on the premises, check cir- cuit breakers and fuses and reset or replace as necessary. CALL FOR SERVICE IMMEDIATELY if AC power cannot be restored.
