100 to 4000 feet per minute (0.5 to 20.32 m/sec.) Patented telescopic sampling tube 12/24 VDC operation Built-in reset button Outside mounting tabs Easy and quick mounting to round or rectangular ducts from 1 ′–12′ (0.3–3.7 meters) wide Photoelectric models available Easy to clean UL recognized field-replaceable power and sensor boards Remote test station option Remote annunciator option Transparent cover for convenient visual inspection UL 268A listed 3-year warranty The System Sensor Innovair™ DH100LP is a 2-wire photoelectric air duct smoke detector capable of sensing smoke in air velocities from 100 to 4,000 feet per minute (0.5 to 20.32 m/sec). This Innovair features Low-Flow technology enabling duct smoke detection throughout a broad range of airflow environ - ments. Many difficult to solve HVAC applications occur in low airflow duct applications where reliable smoke detection is critical. Innovair with Low-Flow technology can detect smoke at air speed velocities of 100 feet per minute or greater, while continuing the same reliable performance to 4,000 feet per minute. The Innovair family is designed for simplified installation and easy maintenance. The modular construction allows for easy cleaning and uncomplicated field replacement of the UL recognized power and sensor boards. 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 DH100LP 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 100 feet per minute to 4000 feet per minute (0.5 to 20.32 m/sec.). 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.
