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.

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.

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.

Refer to NFPA 72 and 90A for additional information.
