Troubleshooting
Other Fire Alarm System Events
The system status data, uploaded from the fire panel into PS-Tools, displays all the panel faults, in
addition to the faults in zones, NACs, and relays. Maintenance signals are generated when the
detector becomes dirty. A separate supervisory freeze signal is generated when the ambient
temperature falls below the detector rating of about 45
o F.
Resolution: Supervise the field wiring for each zone for open circuits, shorts, and ground faults.
All the faults are visually and audibly annunciated.
