The System Sensor DH100 2-wire duct smoke detector is available as a

photoelectronic model. This new design allows for simplified cleaning and

maintenance. 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 SMOKE 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 smoke detector

application information.
