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, preventing the spread of toxic smoke and fire
gases through the protected area.
System Sensor DH100 2-wire duct smoke detector is
available as either an ionization or photoelectric model.
This new design allows for simplified cleaning and
Refer to NFPA 72 and 90A for additional duct detector
application information.

DUCT DETECTORS ARE:
NOT a substitute for an open area smoke detector,
NOT a substitute for early warning detection, and
NOT a replacement for a building’s regular fire
detection system.

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.
