DH400ACDC Duct
Detector Components
Architectural/Engineering Specifications
The air duct smoke detector shall be a System Sensor
Model DH400ACDC 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. The detector housing shall be
equipped with an integral mounting base capable of
accommodating either photoelectronic or ionization
detector heads. It shall be capable of local testing via
magnetic switch or remote testing using the RTS451KEY
Remote Test Station. 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 be installed after the housing is mounted to the
duct by passing through the duct housing. Terminal
connections shall be of the strip and clamp method
suitable for 14–18 AWG wiring.
