Multi-sensor detector capabilities and comparative performance with smoke detectors

The early detection of fire is necessary to allow occupants of a building more time to escape and allows for interventions to protect property. Trying to get the balance right of early detection without false alarms in a broad range of applications in the service environment is a challenge as detection of smoke like phenomena such as steam, aerosols and dust can trigger smoke detectors which contribute to unwanted false alarms.

Multi-sensor detectors are considered to be less prone to false alarms from sources that do not produce any heat. This has been claimed from anecdotal accounts of false alarm causes as investigated during the previous BRE Trust research projects into false alarms. Generally, there is a lack of understanding in the market today about multi-sensor detector capabilities and the aim is to perform the underpinning research that will validate their performance and provide the necessary guidance to the fire industry.
