Marine 601P-M Optical Smoke Detector
601P-M detectors are capable of detecting the visible smoke
produced by materials which smoulder or burn slowly, i.e. soft
furnishings, plastic foam etc; or "smoke" produced by
overheated but unburnt PVC. These detectors are particularly
suitable for general applications and areas where cable
overheating may occur, e.g. electrical services areas.
only detectors are not suitable for detecting fast burning fires
producing little visible smoke or very black smoke.
The novel design of the asymmetrical sampling chamber and signal processing techniques stop unwanted alarms caused by very small insects, i.e. thrips. Smoke entering the sampling chamber scatters the infra-red light pulses onto a photodiode.
