The DH100 Series, 4-wire duct housing
will accommodate either the ionization sensor or the photoelectronic
sensor. The twist-in, twist-out detector heads allow easy removal
for quick cleaning and maintenance, or a change in application
without removing the duct housing. The DH100 samples air currents
passing through a duct and gives dependable performance for
management of fans, blowers, and air conditioning systems.
The air duct smoke detector shall be a Greystone Model
DH100ACDC Series Duct Smoke Detector. The detector housing shall
be ULC/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.
