Innovair Duct Smoke Detector Specifications
Architectural/Engineering Specifications
The air duct smoke detector shall be a System Sensor Model DH100ACDCI 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 (2.54 to 20.32 meters/
second). The unit shall be capable of controlling up to ten (10) air handling systems when interconnected with other detectors. The detector shall be capable of
providing a trouble signal in the event that the front cover is removed. It shall be capable of local testing via magnetic switch or remote testing using the SSK451
Multi-Signaling Accessory or the RTS451KEY Remote Test Station. The unit shall be reset by local reset button or remote test station. The duct smoke 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 by passing through the
duct housing after the housing is mounted to the duct. The unit shall provide a spacial separation of no less than ¼˝ (6.4 mm) and/or a physical barrier between
the high and low voltage terminals. 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.
