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.
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 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
??????????????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.

Innovair Duct Smoke Detector Specifications
Architectural/Engineering Specifications
The air duct smoke detector shall be a System Sensor Model DH100ACDCI Series Duct Smoke Detector. The detector housing shall be UL listed per UL 268A specifically for use in air handling systems. The detector shall operate at air velocities of 500 feet per minute to 4000 feet per minute (2.54 to 20.32 meters/ second). The unit shall be capable of controlling up to ten (10) air handling systems when interconnected with other detectors. The detector shall be capable of providing a trouble signal in the event that the front cover is removed. It shall be capable of local testing via magnetic switch or remote testing using the SSK451 Multi-Signaling Accessory or the RTS451KEY Remote Test Station. The unit shall be reset by local reset button or remote test station. The duct smoke detector housing shall incorporate an airtight smoke chamber in compliance with UL 268A, Standard for Smoke Detectors for Duct Applications. The housing shall be capable of mounting to either rectangular or round ducts without adapter brackets. An integral filter system shall be included to reduce dust and residue effects on detector and housing, thereby reducing maintenance and servicing. Sampling tubes shall either be telescoping or be easily installed by passing through the duct housing after the housing is mounted to the duct. The unit shall provide a spacial separation of no less than ?? (6.4 mm) and/or a physical barrier between the high and low voltage terminals. The enclosure shall meet all applicable NEC and NFPA standards regarding electrical junction boxes. Terminal connections shall be of the strip and clamp method suitable for 12–18 AWG wiring.
