Autocall Duct Detector Housings with TrueAlarm Photoelectric Detector for Stand-Alone Operation

UL ULC CSFM Listed Smoke Detectors Detector Housings with TrueAlarm Photoelectric Detector for Stand Alone Operation Operation an alarm is detected the on board relay contacts transfer the control tone alert sounds and the alarm LED illuminates Activating the switch will silence the tone alert After the source of the alarm is and resolved turning the key switch to Test Reset will reset the Relay Operation output relay contacts are held energized during normal operation loss of power or removal of the detector the contacts will transfer stand alone operation air duct detector housing with cover to monitor for the presence of smoke factory installed TrueAlarm photoelectric smoke and features On board TrueAlarm sensitivity drift compensation and dirt tracking Multi function status LED indicator on detector Magnetic test that initiates an alarm and provides detailed diagnostic Clear cover allows visual inspection Test ports provide functional smoke testing access with cover in place Input power of 120 VAC 24 VAC or 24 VDC UL listed to Standard 268A relay output features Fail safe operation that is normally energized and transfers upon loss of power or detector removal Contacts are Form C rated 5 A 120 VAC or 28 VDC resistive requires Control Station A4098 9842 Provides power on LED alarm LED local tone alert signal local tone silence and keyed test reset switch Control station is ordered separately to rectangular ducts or round ducts Minimum size is 8 203 mm square or 18 457 mm diameter operated functional test Initiates alarm and displays dirt accumulation status using the detector LED dirty detectors Assists with maintenance priorities by categorizing detector status and tubes ordered separately Available in multiple lengths to match duct size Installed and serviced with housing in place Please note that smoke detection in air ducts is intended to provide of the presence of smoke in the duct It is not intended to will not replace smoke detection requirements for open areas or non duct applications Operation A4098 9687 stand alone duct detector housings with smoke are for applications that operate independent of a fire alarm panel They provide a TrueAlarm smoke detector for monitoring conditioning or ventilating ducts Sampling tubes are installed into duct allowing air to be directed to the smoke detector mounted in housing

normal compensation is malfunctioning or other service is is required Testing requires placing a magnet at the designated location on the duct housing cover for 4 seconds and referring to the response from the red status indicator on the detector Refer to Installation Instructions 574 777AC for further test and maintenance information 2 Rev 7 1 2020 Duct Detector Location Reference Detector Housings with TrueAlarm Photoelectric Detector for Stand Alone Operation Information Refer to NFPA 90A Standard for the Installation of Air Conditioning and Ventilating Systems NFPA 72 the National Fire Alarm Signaling Code and the NEMA Guide for Proper Use of Smoke Detectors in Duct Applications and Installation Instructions 574 776AC Detector Location Considerations Proper duct smoke detection location must ensure adequate airflow within the duct housing Duct air velocity rating is 300 to 4000 ft min 91 to 1220 m min Pressure differential between intake and exhaust tubes is required to be 0.015 to 1.55 inches of water 0.381 to 39.37 mm Ensure accessibility for test and service Proper Locations downstream side of filters to detect fires in the filters in return ducts ahead of mixing areas upstream of air humidifier and coil Other locations and orientations may be required for proper duct smoke detection depending on duct access system design and duct airflow Contact your local Autocall product supplier for assistance to Avoid Where dampers closed for comfort control would interfere with airflow Next to outside air inlets unless the intent is to monitor smoke entry from that area return air damper branch ducts and mixing areas where airflow may be restricted 3 Rev 7 1 2020 Detector Housings with TrueAlarm Photoelectric Detector for Stand Alone Operation Selectable at
