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

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.

WARNING:

Duct smoke detectors have specific limitations.

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.

Refer to NFPA 72 and 90A for additional duct detector

application information.
