L
Burglary Notification Appliance Circuits must be programmed for a timeout of 16 minutes or longer.
Commercial fire alarm systems require Notification Appliance Circuits to be supervised.
Notification Appliance Circuit Supervision
The VISTA-128FBP/VISTA-250FBP monitors the Notification Appliance Circuits wiring for open and short circuit faults
while the output is inactive. The system provides a trouble indication (Zone 970 Bell 1; 971 Bell 2) when an open occurs.
When a short occurs between the Bell (+) and Bell (-) terminal wiring, or between the Bell (+) terminal wiring and earth
ground the system provides a trouble indication (972 Earth Ground).
The VISTA-128FBP/VISTA-250FBP indicates the trouble condition regardless of whether the system is armed or
disarmed. The zone displays on the keypads, reports to the event log, and transmits to the central station (if
programmed) on Partition 1. The trouble is cleared from the display by entering the user code + OFF.
