NEMA 4-rated InnovairFlex watertight duct smoke detectors operate in the most challenging conditions without the need for bulky enclosures. They can operate in airflow speeds from 100 to 4,000 feet per minute, temperatures from -4° to 158°F.
NEMA 4-rated InnovairFlex watertight duct smoke detectors operate in the most challenging conditions without the need for bulky enclosures. They can operate in airflow speeds from 100 to 4,000 feet per minute, temperatures from -4° to 158°F, and humidity ranges from 0 to 95 percent (non-condensing).
If space is a problem or to save time and money (up to 30 percent), monitor supply and return detectors from a single power board using InnovairFlex’s semi and fully distributed 2-to-1 sensor to power board capability.
Remote testing capability has been added to the updated Series DNR and watertight NEMA DNRW InnovairFlex™ intelligent duct smoke detector housing with the intelligent Remote Test Capable® photoelectric detector (2251BR). This optional detector is especially designed for use in applications requiring a remote test.
