Resumen del manual


This detector is specially designed for use in either indoor or outdoor applications to provide a degree of protection against falling dirt, rain, sleet, windblown dust, splashing water and hose-directed water. The DH100ACDCLWP is listed for an extended air speed range of 100 to 4000 feet per minute (0.5 m/s to 20.2 m/s). IMPORTANT NOTES The following temperature limitations must be observed during the installation and handling of this product: Operating temperature: +32° to +131°F (0° to + 55°C) Storage temperature: –22° to +158°F (–30° to +70°C) To maintain the watertight properties of this duct smoke detector, watertight conduit and fittings must be used. Mount the product with the conduit holes facing downwards, if possible. Before Installing Please thoroughly read the System Sensor Guide for Proper Use of Smoke Detectors in Duct Applications, which provides detailed information on detector spacing, placement, zoning, wiring, and special applications. Copies of this manual are available online at or via System Sensor’s toll free fax-back service, Documents on Demand at 800/736-7672. NFPA Standards 72 and 90A should also be referenced for detailed information. NOTICE: This manual shall be left with the owner/user of this equipment. IMPORTANT: This detector must be tested regularly following NFPA 90 requirements. The detector should be cleaned at least once a year.

Smoke introduced into this air duct system will be distributed to the entire building. Smoke detectors designed for use in air duct systems are used to sense the presence of smoke in the duct. Model DH100ACDCLWP Air Duct Smoke Detector is supplied as a photoelectronic model. This smoke detection method is combined with an efficient housing design that samples air passing through a duct and allows detection of a developing hazardous condition. When sufficient smoke is sensed, an alarm signal is initiated 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 DH100ACDCLWP detector is designed to operate on 24 VDC/VAC, 120 VAC, or 240 VAC. Alarm and supervisory relay contacts are available for control panel interface (alarm initiation), HVAC control, and other auxiliary functions. Auxiliary relays are also provided for fan shut down or signaling of up to 9 other detectors in the loop for multiple 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. Prior to cover installation, the green LED should be flashing, indicating that the detector is powered and functioning. To accurately determine detector status following installation, System Sensor offers a variety of remote annunciation and test accessories. The DH100ACDCLWP can be reset by a momentary power interruption, the reset button on the front cover, the control panel, or remote reset accessory. The DH100ACDCLWP incorporates a cover tamper feature that provides a trouble signal after 7 minutes if the cover is removed or improperly installed. Proper reinstallation 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 substitute for early warning in a building’s regular fire detection system. System Sensor supports this position and strongly recommends that the user read NFPA Standards 90A, 72, and 101. The DH100ACDCLWP 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. D200-24-00 1 I56-0056-07R This device will not sense smoke unless the ventilation system is operating and the cover is installed. For this detector to function properly, it MUST be installed according to the instructions in this manual. Furthermore, the detector MUST be operated within ALL electrical and environmental specifications listed in this manual. Failure to comply with these requirements may prevent the detector from activating when smoke is pres...
