[1] General Description

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

or signaling of up to 9 other detectors in the loop for mul- tiple fan shut down. These detectors are not designed for 2-wire applications.

For testing, the alarm can be enabled by a magnet activated test switch or by the optional remote test station. The duct smoke detector latches into alarm state when an alarm occurs. A green LED flashes to indicate power, a red LED signals local alarm indication, and optional accessories offer a variety of annunciation capabilities.

The DH100ACDCP can be reset by a momentary power interruption, the reset button on the front cover, the control panel, or remote reset accessory. The DH100ACDCP incor- porates a cover tamper feature that provides a trouble signal after 7 minutes if the cover is removed or improp- erly installed. Proper installation of the cover removes the trouble condition.

[2] Limitations Of Duct Smoke Detectors

WARNING

The National Fire Protection Association has established that DUCT DETECTORS MUST NOT BE USED AS A SUBSTITUTE FOR OPEN AREA DETECTOR PROTECTION as a means of providing life safety. Nor are they a substi- tute for early warning in a building’s regular fire detection system.

System Sensor supports this position and strongly recom- mends that the user read NFPA Standards 90A, 72, and 101. The DH100ACDCP Air Duct Smoke Detectors are listed per UL 268A.

WARNING

Model DH100ACDCP Air Duct Smoke Detector utilizes photoelectric technology for the detection of smoke. This detection method, when combined with an efficient hous- ing 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 action can be taken to shut off fans, blowers, change over air handling systems, etc. These actions can facilitate the management of toxic smoke and fire gases throughout the areas served by the duct system.

The DH100ACDCP detector is designed to operate on 24 VDC/VAC, 120 VAC, or 240 VAC. Alarm and supervi- sory relay contacts are available for control panel interface (alarm initiation), HVAC control, and other auxiliary func- tions. Auxiliary relays are also provided for fan shut down

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 protec- tion specialist.

WARNING

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

WARNING

For this detector to function properly, it MUST be installed according to the instructions in this manual. Furthermore, the detector MUST be protected from the elements and operated within ALL electrical and environmental specifi- cations listed in this manual. Failure to comply with these requirements may prevent the detector from activating when smoke is present in the air duct.
