Systemsensor A5052 4-wire ionization duct smoke detector Datasheet

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.
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
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.
• A patented cover-tamper trouble signal
• A transparent cover
• A remote test station
• Remote sounder/LED indicator options
• A built-in reset button

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 ¼˝ (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.

Important Interconnect Notes
• When using the interconnect feature, all interconnected units must be powered with the same, independent supply.
•Polarity must be maintained throughout the interconnect wiring. Connect terminal 12 on unit 1 to terminal 12 on unit 2 and so on. Similarly, connect
terminal 1 on unit 1 to terminal 1 on unit 2 and so on.
