Unwanted (“False”) Alarms

Technology is improving all the time; however the false alarm rate from fire detection and alarm systems remains fairly constant – NZ Fire Service figures indicate that more than 90% of such calls are unwanted (“false”) alarms. With more and more systems being installed, the overall demand on Fire Service resources is increasing.

False alarms disrupt – business, staff, and customers. Repeated false alarms lead to complacency, and alarms being ignored. The Fire Service also levies callout charges for systems which repeatedly give unwanted alarms.

Correct detector selection and placement is of utmost importance in reducing false alarms. Other important measures are the control of building work, good building maintenance, regular detection system maintenance, and premises security
