C-Tec C4414 ActiV Multi-Sensor Combined Optical Smoke Heat Detector

C-Tec C4414 ActiV Multi-Sensor Combined Optical Smoke Heat Detector

C-Tec ActiV Multi-Sensor Combined Optical Smoke Heat Detector - C4414The C4414 Multi-sensor fire detector incorporates two sensors one for smoke and one for heat. As well as operating independently the signals from the two sensors combine to produce a more sensitive response to freely burning fires. For example when the detectors heat sensor detects an increase in temperature it reduces the level at which its smoke sensor will respond.This smoke heat analysis means that the detector not only provides excellent detection across the widest range of fire types but also provides very effective false alarm reduction. As a result the multi-sensor is the most effective all round detector. It is particularly useful in accommodation areas such as student premises HMOs sheltered housing blocks etc. which are much more susceptible to nuisance alarms.Other detectors from the ActiV range include C4403A1R which is a Rate of Rise Heat Detector C4403A2 which is a 60C Fixed Heat Detector C4416 which is a Optical Smoke Detector and the C4403B which is a 75C Fixed Heat DetectorKey FeaturesA high-quality combined optical heat multi-sensor offering outstanding detection performance at a very competitive priceManufactured by C-TEC in the UKThird-party certified to EN54-5 7 by IntertekCarries the pan-European CertAlarm markWide 6-33V DC operating voltageTwo 8mm x 2mm ultra-bright red LED indicating strips offering 360 visibilityDrift compensation functionality ensures detector sensitivity is automatically calibrated to suit prevailing conditions andor increased contamination levelsCompatible with our ActiV C4408D diode C4408 non-diode and C4408R relay bases all bases include an integrated detectorbase locking mechanism and ID tagClass A1 fixed heat class B fixed heat class A1R rate-of-rise and optical variants also availableExcellent discounts for quantity orders
