2-Wire Low-Profile Duct Smoke Detector A Division of Pittway 3825 Ohio Avenue, St. Charles, IL 60174 1-800-SENSOR2 (736-7672), Fax 630-377-6495 http://www.systemsensor.com Models Available DH100I 2-wire Ionization Detector DH100P 2-wire Photoelectronic Detector Features Outside mounting tabs Telescoping sampling tube* Built-in reset button Easy to clean 12/24 VDC operation Ion or photo models available Remote test station option Air velocity rating from 500 to 4000 FPM Remote annunciator option Easy and quick mounting to round or rectangular ducts from 1′–12′ wide • Textured cover for convenient visual inspection • UL 268A listed • 3-year warranty maintenance, or a change in application without removing the duct housing. The DH100 samples air currents passing through a duct and gives dependable performance for management of fans, blowers, and air conditioning systems, preventing the spread of toxic smoke and fire gases through the protected area. System Sensor DH100 2-wire duct smoke detector is available as either an ionization or photoelectric model. This new design allows for simplified cleaning and Refer to NFPA 72 and 90A for additional duct detector application information. • • • • • • • • • • WARNING: Duct smoke detectors have specific limitations. DUCT DETECTORS ARE: NOT a substitute for an open area smoke detector, NOT a substitute for early warning detection, and NOT a replacement for a building’s regular fire detection system.

A05-976-00 Architectural/Engineering Specifications The air duct smoke detector shall be a System Sensor Model DH100 Series Duct Smoke Detector. The detector housing shall be UL listed per UL 268A specifically for use in air handling systems. The detector shall operate at air velocities of 500 feet per minute to 4000 feet per minute. It shall be capable of local testing via magnetic switch or remote testing using the RTS451KEY Remote Test Station. The unit shall be reset by local reset button or RTS451KEY. The duct detector housing shall incorporate an airtight smoke chamber in compliance with UL 268A, Standard for Smoke Detectors for Duct Applications. The housing shall be capable of mounting to either rectangular or round ducts without adapter brackets. An integral filter system shall be included to reduce dust and residue effects on detector and housing, thereby reducing maintenance and servicing. Sampling tubes shall either be telescoping or be easily installed after the housing is mounted to the duct by passing through the duct housing. The enlosure shall meet all applicable NEC and NFPA standards regarding electrical junction boxes. Terminal connections shall be of the strip and clamp method suitable for 12-18 AWG wiring.
