DDA Detector of Smoke and Combustion Products

The DDA provides early detection of smoke and combustion products present in air moving through HVAC ducts in commercial, industrial, and residential applications. It is compatible with the PFC-6000 series addressable FACPs and any panel which utilizes the Potter/Nohmi addressable protocol. The DDA uses state-of-the-art addressable sensors and control modules to provide flexibility in tackling demanding applications. With a listed air velocity of 100 to 4,000 ft/minute, it will function in an array of conditions and duct systems. The STN sampling tubes do not require tools for installation or testing, as a test port is available for testing the installed unit as required.
