Duct Smoke Sampling System

Our UG-4 single-pipe duct smoke detector is used to prevent the spread of smoke in a ventilation system.

As it only has one pipe, UG-4 is easy to install and operate.

The detector has been developed to detect smoke in ventilation ducts and combining a smoke detector and an adaptor system where both venturi pipe and housing are specially designed for optimum airflow through the smoke detector.
