NFPA: Understanding Unwanted (Nuisance) Alarms Video

The American National Fire Protection Association (NFPA) recently hosted a 1.5 hour webinar for fire industry professionals and fire departments to provide a background, information and tools to help deal with unwanted alarms.

Can steam operate a smoke detector?

I received an email (below) from a customer (MB) who had experienced an alarm, likely caused by steam from a shower in a washroom.

Hi Russ,

We had a fire alarm last week in toilet/wet area due to pressure hosing. Evidently it was a smoke detector set off due to water mist.

Could you please provide feedback whether thermal detectors suffer potential false activations from minor water spray or if this is really only likely from smoke detectors?

Contaminated (dirty) Smoke Detectors

Contaminated Smoke DetectorBy its very design a smoke detector is intended to detect the presence of contamination from airborne particles, typically smoke.

Unfortunately there are a great deal of other particles that when built up over time can adversely affect the performance of a smoke detector.

This adverse affect can be reflected in two ways;

Humidity and nuisance alarms

Extending on from my recent blog on the Brisbane floods and the affect on fire & life safety, the uncanny summer weather in Melbourne has caused another problem.

The weather in Melbourne this summer has been quite tropical with a weather pattern extending form Far-North-Queensland all the way down to Tasmania.

This weather pattern has also led to a significant increase in the level of of relative humidity1 as reported by the Bureau of Meteorology. The relative humidity has been in excess of 85% for the period Jan 10 to Jan 13 which is significantly up on the average for this month to date, and the average over the past few years.
