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.
