This section describes isolating and de-isolating zones. Isolating a zone does not prevent any of
the points within the zone from going into the alarm state, but does prevent the activation of any
outputs that are programmed to operate when the zone is in alarm.
Pressing the <ISOLATE> key on a Zone Isolate module toggles the Isolate status. I.e., if the
state of the zone is de-isolated, pressing the key isolates the zone. Likewise, if the state of the
zone is isolated, pressing the key de-isolates the zone.
A zone is isolated by pressing the appropriate Zone Isolate key on the Zone Isolate Module. Zone
Isolate modules are located below the Operator Interface. Each Zone Isolate Module supports 8
zones.
1. Press the ISOLATE key so that the Zone Isolate LED turns on. (Do not hold the key down).
2. Press the <ISOLATE ACK> key to acknowledge the isolate operation.
Zones are de-isolated by pressing the appropriate Zone Isolate key on the Zone Isolate Module.
1. Press the ISOLATE key so that the Zone Isolate LED turns off.
2. If individual acknowledge operation is selected, press the <ISOLATE ACK> key to
acknowledge the de-isolate operation.
