Notifier SD-851EA PhD Low-Profile 800 Series Conventional Optical Smoke Detector
Notifier SD-851EA PhD Low-Profile 800 Series Conventional Optical Smoke DetectorPhD low profile 800 Series conventional optical smoke detector. The SD-851E photoelectric smoke detector incorporates an optical chamber which is continually monitored by an on board processor which uses algorithms developed specifically for the unit. An alarm signal is only enabled in the detector once the processor is satisfied that a real fire has been detected thereby reducing the incidence of nuisance alarms.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 compensationProgrammable 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 warrantyComes with a PROGRAMMABLE feature set removable cover insect screen LASER test and device status transmission to handheld programmer
