Notes: 

maintenance should be performed by authorised personnel.

 

 

3.1  Inspection  

 

The following steps must be taken in accordance with local standards:

 

 

1.  Check the LEDs at the front for fault indications;  

 

2.  Note any indications in your report;  

 

The  following  pages  illustrate  the  maintenance  procedures  to  be  carried  out  for  the  detector.  These 
procedures are only intended for authorised personnel.

 

 

3.2  Service  

 

Notes: 

service procedures must only be carried out by qualified service technicians.

 

 

Make sure the site managers and relevant authorities have been informed and, where necessary, that the 
detector outputs have been isolated in order to prevent accidental activations and alarm indications in the 
building.

Filter replacement depends on the clouding level read by the detector during normal operation. The interval 
shown above is suitable for a normal room (e.g. an office). Consider more frequent maintenance in dirtier 
and more critical environments.
