2-Wire Low-Profile Duct Smoke Detector Model DH100P 2-Wire Photoelectronic Detector DH100P 2-Wire Photoelectronic Detector Product Overview Outside mounting tabs Patented plastic sampling tube UL recognized field-replaceable power and sensor boards Built-in reset button Easy to clean 12/24 VDC operation Photoelectronic 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 ® APPROVED The System Sensor DH100 2-wire duct smoke detector is available as a photoelectronic model. This new design allows for simplified cleaning and maintenance. 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. WARNING: Duct smoke detectors have specific limitations. DUCT SMOKE 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. Refer to NFPA 72 and 90A for additional duct smoke detector application information. 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 plastic or be easily installed after the housing is mounted to the duct by passing through the duct housing. The enclosure 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.
