Contaminated Smoke Detector

This detector was removed from a building where it has was installed. The detector was reading a higher level of contamination that normal but was still within its normal operating parameters.


The accumulation of excess debris on the outside of one side of the detector indicates that it was located adjacent to an outlet from an HVAC system.


In circumstances such as this, additional maintenance precautions must be taken to ensure the operational integrity of the fire alarm system is maintained.
