Innovair Duct Smoke Detector Specifications
Architectural/Engineering Specifications
The air duct smoke detector shall be a System Sensor Model DH100ACDCLWP series watertight duct smoke detector. The detector shall meet the NEMA
4 standard for enclosures for electrical equipment. It shall be UL listed for non-hazardous locations for installation and use in both indoor and outdoor
applications. The detector shall be constructed so as to provide a degree of protection against falling dirt, rain, windblown dust, splashing water, hose-directed
water and incidental contact. 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 20.3 m/sec.). 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
spatial 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.
