Product Overview
Air velocity rating from 100 to 4000 feet
per minute (0.5 to 20.32 m/sec.)
Patented telescopic sampling tube
Easily accessible code wheels 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-
Outside mounting tabs
ute (0.5 to 20.32 m/sec).
Easy and quick mounting to round
or rectangular ducts from 1′–12′
This Innovair features low-flow technology that enables duct smoke detection through-
(0.3–3.7 meters) wide
out a broad range of airflow environments. Many difficult to solve HVAC applications
Easy to clean occur in low airflow duct applications where reliable smoke detection is critical. Innovair
UL recognized field-replaceable low-flow technology can detect smoke at air speed velocities of 100 feet per minute or
power and sensor boards greater, while continuing the same reliable performance to 4,000 feet per minute.
Transparent cover for convenient
visual inspection The DH200 Series Detector samples air currents passing through a duct and gives
UL 268A listed dependable performance for shutdown of fans, blowers, and air conditioning systems,
3-year warranty preventing the spread of toxic smoke and fire gases through the protected area.
