Edwards Signaling Catalog u Intelligent Initiating Bases E PD E PHD E PDD B4U RB4U IB4U SB4U Features Optical smoke heat and multisensor models available Field replaceable optical chamber Highly stable design Compatible standard relay isolator and audible bases Head and terminal base tamper resistent design for fast instal and security Self diagnostic capability with on board storage of data Optical detectors feature automatic rate compensated sensitiv adjustment as well as dirty sensor warnings Manufactured to strict international ISO 9001 standards Low profile aesthetically pleasing design intelligent addressable detectors are meticulously engi to deliver high perfor mance features superb reliability and quality With their highly stable design these detectors air movement caused by heating and air conditioning making reliable performers ideally suited to modern building interiors installation and maintenance advantages of Edwards intel detectors add value throughout their service life The head terminal base design makes short work of installation and opera tions A plastic breakout on the detector optionally pre vents removal from the base except with a tool bi colored LED flashes green for normal operation and red in alarm thus eliminating much of the guesswork when to detector status The houses a replaceable optical sensing chamber that particles produced by smoke The houses a replaceable optical sensing chamber detects smoke as well as a fixed temperature sensor that heat The detector analyzes data from both sensors to when an alarm is initiated The duct

comprehensive self diagnostic capability and E PHD optical detectors continuously adjust their sen reference value to compensate for changes in the environ such as the presence of dirt temperature and humidity detectors issue a dirty sensor warning when they reach preset limit reducing the chance of a nuisance alarm 1 of 6 D A T A S H E E T S85001 0592 to be used for installation purposes Issue 2 details Application intelligent analog device houses an optical chamber that detects smoke as well as fixed temperature sensor that detects heat The analyzes sensitivity reference values from sensors to determine when an alarm is initiated The E PHD capable of performing comprehensive self diagnostics and stor the data detector continuously adjusts its sensitivity reference value on fluctuating environmental conditions such as the pres of dirt humidity or changes in temperature When the detec has adjusted its sensitivity reference value to its maximum limit issues a dirty sensor warning allowing enough of a margin for personnel to clean the detector before it goes into condition E PHD combines the suitability of optical sensing for slow fires with the sensitivity of fixed temperature detection for flaming fires to arrive at a solution that responds reliably to the range of fire types A sophisticated algorithm processes from both sensors over time so that an alarm is only reported conditions precisely match the signature of a fire This elimi the shortcomings of single sensor optical and heat detec and significantly reduces the risk of nuisance alarms intelligent analog device can be configured as a 135F fixed temperature heat sensor or a rate of rise with fixed temperature The sensor monitors the temperature of the air and whether an alarm should be initiated The E HD is of performing comprehensive self diagnostics and storing data to its advanced thermistor technology the E HD detector ideal for sensing fast flaming fires and for applications where detection is inappropriate It is particularly well suited to such as laundries and industries where fluctuations in ambi temperature is expected detector prevents smoke from circulating the building see data sheet S85001 0613 intelligent analog device uses an optical sensing to detect smoke The detector analyzes reference values gathered by the sensor determine when an alarm is initiated The E PD is of performing comprehensive self diagnostics and storing data detector continuously adjusts its sensitivity reference value on fluctuating environmental conditions such as the pres of dirt humidity or changes in temperature When the detec approaches its preset sensitivity reference value threshold it a dirty sensor warning allowing enough of a margin for personnel to replace the optical chamber before it into trouble condition to its high performance optical sensing chamber the E PD quickly and reliably to a wide range of fire types espe slow burn ing fires fuelled by combustibles typically found in multi use buildings The E PD detects extremely small and triggers an alarm at the first sign of smoke Indication detector provides a tri color LED that shows its status Normal Green LED
