Philton Fire and Security has recently installed one of its new Guardian LaserSTAMP smoke detectors systems to protect police holding cells. The system monitors the air for smoke particles within each cell extract duct, minimising the risk of vandalism and self mutilation.
“This is the first of an initial order of six to be installed” said Tony Jacobs, managing director of Philton: “We have spent two years developing this new smoke detector and controller for police holding and prison cells and can see a wide range of other potential applications.”
One of the new product’s features is the ability to differentiate between smoke and dust. This is achieved by use of a ‘laser forward scatter’ system which provides a combined mass detection and particle count, minimising nuisance alarms while providing the highest level of sensitivity.
The new LaserSTAMP provides a detector and independent zone isolator for each zone compared to the original model, which had one detector for up to twelve zones. The advantage is that the speed of detection is improved and if one detector fails, it only affects one zone. Another feature is that the system controller has been designed to provide an optional built in hot standby. It has twin circuits with independent power supplies which mean that if one unit fails, the other automatically takes over without loss of service or alarm history.
