module options ordered separately Red alarm LED A4098 9830 Test stations with LED s and keyswitch refer to page 2 for Relays for remote control applications 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 1 Detector Housing Front and Bottom View Alarm Indicators and Test Stations Autocall air duct smoke detector housings provide a smoke detector for monitoring air conditioning or ventilating Sampling tubes are installed into the duct allowing air to be to the smoke detector mounted in the housing These duct housings with smoke detectors are compatible with Autocall alarm control panels that provide conventional two wire or four wire device circuits IDCs This product has been approved by the California State Fire Marshal CSFM pursuant to Section 13144.1 of the California Health and Safety Code See CSFM Listings 3240

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
