Edwards Signal ED-DH100ACLP Photo DUCT Detector


Our Price : $168.00

Product Code: ED-DH100ACLP


The System Sensor DH100ACDCLP reduces the spread of smoke through HVAC air duct systems, including low-flow applications. As a photoelectric detector, its ultra-responsive to the large smoke particles commonly found in duct systems.

The DH100ACDCLP uses low-flow technology to sense smoke in the lowest air speeds, from 100 to 4,000 feet per minute. When smoke is detected, all interconnected units will initiate their relays. However, to quickly locate the fire source, only the detector sensing smoke will alarm. Two DPDT Form-C relay contacts, connected to auxiliary equipment, can also be configured to prevent the spread of smoke through a particular area.

The DH100ACDCLP is simple to install and maintain. Powered by 24 VAC/DC or 120/240 VAC, it can be easily mounted to round and rectangular ducts, from one to twelve feet in width, with outside mounting tabs. It also offers an adjustable telescopic sampling tube that can be used for duct widths up to 18 inches. This tube locks into place; no additional tools are necessary.

Its modular construction allows for easy cleaning and field replacement of the power and sensor boards. Also simplifying maintenance is a transparent cover that provides convenient visual inspection. If the cover is removed, a patented covertamper trouble signal gives a 7-minute delay before the panel or remote accessory is notified of trouble.

At a remote location, the remote test station option ensures that a detector is functioning properly and the remote sounder/ LED indicator option signals if a detector is in alarm. However, the cover does not need to be removed if a detector needs to be reset at the detector. Simply push the built-in reset button.
