Architect/Engineer Specifications
The air duct smoke detector shall be a System Sensor
Model DH400ACDCIHT Series Duct Smoke Detector.
The detector shall be UL listed per UL S911, standard
for Smoke Detectors for Duct Applications, specifically
for use in air handling systems. The detector shall oper-
ate at air velocities from 500 feet per minute to 4000
feet per minute. The detector shall have an operating
temperature range of 32˚F to 158˚F. The detector housing
shall be equipped with an integral mounting base capable
of accommodating ionization detector heads. It shall be
capable of local testing via magnetic switch or remote test-
ing using the RTS451KEY or RTS451 Remote Test Station.
The duct detector housing shall incorporate an airtight
smoke chamber in compliance with UL S911. The housing
shall be capable of mounting to rectangular or round ducts
up to 12′ wide 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.
