4-Wire Ionization
Duct Smoke Detector
System Sensor’s Innovair DH100ACDCI reduces the
spread of smoke through HVAC air handling systems.
As an ionization duct detector, it’s ultra-responsive to
submicron-sized smoke particles typically found near
a fire source.
The DH100ACDCI senses smoke in velocities from 500 to 4,000 feet
per minute. When smoke is detected, all interconnected Innovairs
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.
Features
• Ionization technology
• An air velocity rating from 500 feet per minute to 4,000 feet per
minute (2.54 meters per second to 20.32 meters per second)
• Patented interconnectability for multi-fan shutdown
Beyond its reliable performance, the DH100ACDCI 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. The 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.
• Two DPDT Form-C relay contacts
• 24 VAC/DC or 120/240 VAC
• Versatile mounting options
• Outside mounting tabs
• A patented telescopic sampling tube
• Modular construction
• A patented cover-tamper trouble signal
• A transparent cover
• A remote test station
• Remote sounder/LED indicator options
• A built-in reset button
At a remote location, the remote test station option ensures that
a detector is functioning properly, and the remote sounder/LED
indicator options signal 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 building’s regular fire detection system.
