Notifier SD-851TE Conventional Multi Detector
Notifier SD-851TE Conventional Multi DetectorThe SD-851TE photoelectric smoke thermal detector incorporates an optical chamber and a thermal element which in turn are continually monitored by an on board processor by using algorithms developed specifically for the unit. An alarm signal is only enabled in the detector once the processor is satisfied that an actual fire has been detected. By using a combination of inputs the incidence of nuisance alarms is reduced while at the same time the response time to an actual fire is also improved.A variety of detector bases are available providing compatibility with a wide range of Fire Alarm Control Panels making it ideal for expansions and retrofit applications. The remote hand-held programming tool can also be used in conjunction with the PhD series of detectors to gain access to other enhanced features. The features available include readwrite last maintenance date read chamber contamination level read value of thermal element and perform an alarm test.Key FeaturesAutomatic drift compenstationProgrammable SensitivityAdvanced maintenance features via remote hand-held test unitLow profile designLow current drawWide operating voltage 8 to 30VDCBi-colour LED detector status indicatorAddressable alarm location featureApproved to EN54 part 7 20003 Year warranty
