of Smoke Detectors in Duct Applications I56 473 which detailed information on detector spacing place zoning wiring and special applications Copies of this are available from System Sensor NFPA Standards 72 90A should also be referenced for detailed information This manual should be left with the owner user this equipment This detector must be tested and maintained following NFPA 72 requirements The detector be cleaned at least once a year of Contents 1 General Description Limitations of Duct Smoke Detectors Exploded View of Duct Smoke Detector Components 2 Contents of the Duct Smoke Detector Kit Installation Sequence Duct Smoke Detector Maintenance and Test Procedures 5 Detector Cleaning Procedures Board Replacement Specifications General Description HVAC system supplies conditioned air to virtually every of a building Smoke introduced into this air duct sys will be distributed to the entire building Smoke detec designed for use in air duct systems are used to sense presence of smoke in the duct DH100ACDC Air Duct Smoke Detectors are supplied an ionization model or photoelectronic model These smoke detection methods are combined with an effi housing design that samples air passing through a and allows detection of a developing hazardous condi When sufficient smoke is sensed an alarm signal is at the fire control panel monitoring the detector appropriate action can be taken to shut off fans blow change over air handling systems etc These actions facilitate the management of toxic smoke and fire gases the areas served by the duct system detectors are designed to operate on 24 VDC 120 VAC or 240 VAC Alarm and supervisory relay con Division of Pittway 3825 Ohio Avenue St Charles Illinois 60174 FAX 630 377 6495 are available for control panel interface alarm initia HVAC control and other auxiliary functions Auxiliary are also provided for fan shut down or signaling of up 9 other detectors in the loop for multiple fan shut down detectors are not designed for 2 wire applications testing the alarm can be enabled by a magnet acti test switch or by the optional remote test station duct smoke detector latches into alarm state when an occurs A green LED flashes to indicate power a LED signals local alarm indication and optional ac offer a variety of annunciation capabilities DH100ACDC can be reset by a momentary power in the reset button on the front cover the control or remote reset accessory Limitations Of Duct Smoke Detectors National Fire Protection Association has established DUCT DETECTORS MUST NOT BE USED AS A SUB FOR OPEN AREA DETECTOR PROTECTION as a of providing life safety Nor are they a substitute for warning in a building regular fire detection system Sensor supports this position and strongly recommends the user read NFPA Standards 90A 72 and 101 The Air Duct Smoke Detectors are listed per UL 268A device will not operate without electrical power situations may cause an interruption of power The safeguards should be discussed with your local fire specialist device will not sense smoke unless the ventilation sys is operating and the cover is installed this detector to function properly it MUST be installed to the instructions in this manual Furthermore detector MUST be protected from the elements and op within ALL electrical and environmental specifica listed in this manual Failure to comply with these may prevent the detector from activating smoke is present in the air duct Figure 1 Exploded View Of Duct Smoke Detector Components 10 Wiring diagrams for optional accessories see
