Edwards Data Sheet 521 Series Smoke Detectors

Edwards Signaling Catalog u Conventional Initiating Detectors Auxiliary Functions Series Features Remote maintenance CleanMe reporting and built drift compensation reduces false alarms Self diagnostics meets NFPA 72 sensitivity testing re without the need for external meters Field replaceable optical chamber makes service fast and Large SEMS screw terminals accept 12 18 AWG wire Small low profile design blends with any environment Optional auxiliary functions include Integral sounder with optional tandem interconnection Auxiliary relay Listed for applications such as elevator recall Integral fixed ROR heat detectors brand 500 Series two wire conventional photoelectric detectors bring together trusted technology and a full line features that meet the demands of every type of application 500 offers sounders in two wire applications specifically to residential code requirements is also proud to offer proven technology like CleanMe compensation field replaceable optical chambers and self CleanMe is only available on the 500 2 wire models will communicate with compatible FACPs when servicing is Series detectors work on a light scattering principle A pulsed light emitting diode serves as the light source and a high photo diode as the sensing element This design has supe protection against nuisance alarms caused by dust insects interference and ambient light proprietary optical chamber is field replaceable In the event of confirmed alarm the LED will light continuously The unit indi trouble by flashing the LED every second This meets the 72 field sensitivity testing requirements diagnostic information is activated by applying a magnet the detector integral reed switch This initiates a self diagnostic and provides visual indication of sensitivity level or if service required The magnet test causes the LED to blink The number of counts corresponds to a smoke detector sensitivity range with a built in 85dB sounders emit the temporal 3 pat and can be easily tandemly interconnected using the 405 05 reversal relay This enables all detectors to sound when initiating detector sounds and meets the requirement of the Residential Building Code IRC 1 of 4 D A T A S H E E T S85001 0606 to be used for installation purposes Issue 2 Series detectors are ideal for both retrofit applications and installations alike They are particularly well suited for instal where detector reliability is essential but where typical may not be appropriate or feasible With their optical chambers these detectors are equally well to dusty environments where detectors require frequent fixed temperature sensor LED rate of rise sensor sensor optical chamber bug screen cap and Installation Series detector bases mount directly to standard single gang boxes three inch round or four inch octagonal boxes heads simply twist onto the base Heads are equipped a break away locking tab which prevents unauthorized re SEMS terminals accept 24 to
