The System Sensor Innovair™ DH200 Low-Flow Series photoelectric air duct smoke
detectors are capable of sensing smoke in air velocities from 100 to 4,000 feet per min-
ute (0.5 to 20.32 m/sec).
This Innovair features low-flow technology that enables duct smoke detection through-
out a broad range of airflow environments. Many difficult to solve HVAC applications
occur in low airflow duct applications where reliable smoke detection is critical. Innovair
low-flow technology can detect smoke at air speed velocities of 100 feet per minute or
greater, while continuing the same reliable performance to 4,000 feet per minute.
The DH200 Series Detector samples air currents passing through a duct and gives
dependable performance for shutdown of fans, blowers, and air conditioning systems,
preventing the spread of toxic smoke and fire gases through the protected area.
These intelligent sensors communicate and are continuously monitored through the com-
munication line. Detector sensitivity changes caused by dirt, temperature, or humidity
are reported to the panel, allowing compensation algorithms to maintain the sensor’s set
sensitivity. An advance indication at the panel specifies the sensor address, allowing for
selected maintenance to be performed as needed.
Remote alarm annunciation can be accomplished by using the RA400Z Remote
Annunciator or the RTS451 or RTS451KEY Remote Test Station. Both these devices
allow testing of the detector from a remote location.
The Innovair family is designed for simplified installation and easy maintenance. The
modular construction allows for easy cleaning and uncomplicated field replacement of
the UL recognized power and sensor boards.
WARNING:
Duct smoke detectors have specific limitations.
DUCT SMOKE DETECTORS ARE:
NOT a substitute for an open area smoke detector,
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 duct smoke detector application information.
