RF JAM DETECTION
The panel can now annunciate an RF jam condition as per UL985 when used in conjunction with a 5881
Series RF Receiver that supports RF jam detection. The RF jam annunciation feature can be enabled by
assigning response type 05 to zone 990 for the first
RF receiver and to zone 988 for the second RF
receiver. This will be interpreted as a trouble regardless of whether the panel is armed or disarmed. The
RF supervisory zones are assigned to all partitions that have RF transmitters or RF keypads for keypad
display, event logging, and dialer reporting purposes. Contact ID Code 344 will be used to report RF
jam faults. Refer to the Installation Instructions provided with the 5881 RF Receiver for information on
installing and configuring the receiver for RF jam detection.
BATTERY TESTING
The panel now runs an extended (10-minute) battery test every 4 hours (instead of the previous 24-hour
test interval) to check on the condition of the battery as per UL985. During this test, the panel PCB and
external peripherals are powered from the battery, and the panel initiates a trouble indication if the
battery voltage is found to be low (less than approximately 11.5V).
BATTERY BACKUP
Household Fire or Combination Household Fire/Burg installations require use of a backup battery that is
sized to provide 24 hours of standby time followed by 4 minutes of alarm time. UL1023 Household
Burg-only installations require use of a backup battery that is sized to provide 4 hours of standby time
followed by 4 minutes of alarm time. Use Tables 2, 3, and 4 (below) to determine the required backup
battery capacity and battery model number. A dual battery harness is supplied that allows two
batteries to be wired in parallel for increased capacity.
