Situations such as malfunctioning detectors and damaged wiring prevent a zone from being
reset, which in turn prevents the system from being reset. Isolating a point / zone allows the
system to be reset while repairs are being made.
1. Acknowledge the alarm, as described in “Acknowledging Alarms” earlier in this chapter.
2. If multiple alarms are present in the system, use the <NEXT> and <PREV> keys, located
in the Firefighter Facility portion of the operator interface panel, to scroll through the
alarm list until the point / zone you want to isolate appears in the display. In the example,
below, there are five alarms in the system (1 of 5 appears in the lower right corner).
3. Press the <ISOLATE> key. (This key is located in the Firefighter Facility.) The display
updates, directing you to press the <ACK> key to confirm the isolate operation.
4. Press the <ACK> key. The system does the following:
•
Displays two messages “Processing Action” and “Action Taken.”
•
If this is the first point / zone to be isolated, it illuminates the ISOLATE indicator.
This indicator remains lit until all isolated points / zones are de-isolated.
•
Includes the text “ISOL-ALARM” within the alarm’s text message.
In most cases, you should reset the alarm before de-isolating the point. This prevents the point
from going into an alarm condition again when the point is de-isolated.
