4-Wire Photoelectric,
Low-Flow Duct
Smoke Detector
System Sensors Innovair DH100ACDCLP reduces
the spread of smoke through HVAC air duct systems,
including low-flow applications. As a photoelectric
detector, it’s 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 cover-tamper 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.
WARNING: Duct smoke detectors are NOT a substitute for open
area smoke detectors, NOT a substitute for early warning detection
and NOT a replacement for a buildings regular fire detection system.
Refer to NFPA 72 and 90A for additional information.
