Temporary isolation of a single detector
When has a single detector to be isolated?
Exceptional situations may occur, where it is preferable to isolate only single detector devices instead of the whole detector zone. Such situations may be for example:
nConstruction work with smoke or heat development at a particular location within a large zone with a lot of detectors
nMalfunction of a detector in a zone with several detector devices
WARNING
A detector device that has been isolated cannot trigger any danger or fault messages! As soon as conditions have returned to normal, isolated detector devices have immediately to be switched on again!
If a single detector should be isolated the detector has to be identified clearly! If the detector i cannot be identified clearly, the whole detector zone should be isolated. A wrong isolation of
a detector can cause an unwelcome call of the fire brigade!
