Tyco MR901M Addressable Optical Smoke Detector (Marine)
Unlike conventional style detectors where the detector carries out the “normal” or “ fire alarm” decision with the M900 Series Analogue addressable fire detector, the detectors are acting as transducers relaying an output signal of the sensed phenomenon to the fire controller. The control unit then processes this information either in isolation, or in conjunction with information from other detectors to determine the appropriate response and ultimately make the decision whether or not to raise an alarm.
These 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. 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 These pulses are converted to an electrical signal which is compared against a pre-set alarm level or transmitted as an analogue value.
