[1] General Description

An HVAC system supplies conditioned air to virtually every area of a building. Smoke introduced into this air duct system will be distributed throughout the entire building. Smoke detectors designed for use in air duct systems are used to sense the presence of smoke in the duct.

Model DH100LP Air Duct Smoke Detectors utilizes photo- electric technology for the detection of smoke. This detec- tion method when combined with an efficient housing design samples air passing through the duct and allows detection of a developing hazardous condition. When suf- ficient smoke is sensed, an alarm signal is initiated at the fire control panel monitoring the detector, and appropriate

System Sensor supports this position and strongly recom- mends that the user read NFPA Standards 90A, 72, and 101. The DH100LP Air Duct Smoke Detectors are listed per UL 268A.

WARNING

This device will not operate without electrical power. Fire situations may cause an interruption of power. The system safeguards should be discussed with your local fire protection specialist.

WARNING

This device will not sense smoke unless the ventilation system is operating and the cover is installed.
