Fire Fighting Enterprises FIRERAY 100R - Manual (Page 8)

8. Servicing and Maintenance
During Operating Mode, the following states will be indicated:
 Normal (no Fault or Fire) – Amber LED will flash every 10 seconds (EN approved model)
or not flash at all (UL approved model)
 Fire/Alarm – Red LED will be on continuously, and Fire Relay will close
 Fault – Amber LED on continuously, and Fault Relay will open
 Compensation Fault – Amber LED flashes every 2 seconds
A Compensation Fault will occur when the Detector can no longer compensate for signal
loss due to dust/dirt build-up on the lenses and/or Reflector. A Compensation Fault can be
cleared by cleaning the Reflector and Detector lenses using a dry lint-free cloth, and then re-
aligning the beam. Compensation Faults can be avoided by periodic cleaning of the Reflector
and Detector before compensation limit is reached.
