Tyco 516.020.002 MF301 Ion-Chamber Smoke Detector

Tyco 516.020.002 MF301 Ion-Chamber Smoke Detector

Tyco 516.020.002 MF301 Ion-Chamber Smoke DetectorThe Tyco MF301 Ion-Chamber Smoke Detector 516.020.002 reacts to visible and invisible fire aerosols and is therefore capable of detecting the early presence of hot smouldering and flaming fires such as wood and paper etc.The Tyco MF301 is particularly suitable for general applications in all areas and uses a dual ionisation chamber in which the air is ionised by a single radioactive source 33kBq Americium 241.Key FeaturesPolarising baseOptional locking kitVisual indicationComplies with BS5445Legacy product

Tyco 516.021.002 MR301 Optical Smoke Detector

Tyco 516.021.002 MR301 Optical Smoke Detector

Tyco 516.021.002 MR301 Optical Smoke DetectorThe Tyco MR301 516.021.002 is an optical smoke detector. The Tyco MR301 is designed to detect visible smoke that is produced by materials which smoulder or burn slowly. The MR301 is used in general applications and in areas where cable overheating may occur such as electrical service areas.The design of the asymmetrical sampling chamber and signal processing techniques stop unwanted alarms that are cause by very small insects. Smoke that enters the sampling chamber scatters the infra-red-light pulses onto a photodiode.Key FeaturesLegacy product

Tyco 576.501.204 Symphoni 2 Wire Sounder - Red

Tyco 576.501.204 Symphoni 2 Wire Sounder - Red

Tyco 576.501.204 Symphoni 2 Wire Sounder - RedThe Sounder only models are available with a red or white housing suitable for indoor use and an IP65 rated red housing for outdoor applications.The Audio Visual models which incorporate a high efficiently LED beacon are also available with a red or white housing for indoor use and an IP65 rated red housing for outdoor applications.Up to now sounder circuits have been monitored up to the EOL but not the individual sounders fault detection has relied on human feedback from the weekly tests that should be carried out to meet the requirements of BS5839.The LP Symphoni utilising Reflective Sound Monitoring RSM employs a transducer to actively monitor the units sound output during the weekly sounder test and will report back to the MX controller if it fails to detect the sounder operating when it has been commanded to this ensures that the LP Symphoni range of sounders will in the unlikely event of a fault display it immediately on the fire controller and is therefore not dependant upon the staff within a building reporting a sounder failure.This range of devices is the first of a new range of MX ancillaries to include Line Isolation as standard. As the line lsolator is now integral to the device the need for separate line isolation devices is reduced saving installation time and wiring costs.Key FeaturesColour Red2 wire sounderLegacy product
