UG-3 has been developed to detect smoke in ventilation ducts and combines a smoke
detector and an adapter system, where both tube and housing are specially designed for
optimum airow through the smoke detector. The system meets all the requirements
for safe re detection with airow speeds from 0.2 m/s to 20 m/s. Since the UG-3 is
used with different types of re alarm systems and installations it is delivered without:
• Venturi pipe • Detector
The UG-3 is made for rectangular ducts. The optional UG-MB Mounting bracket has to
be used if the UG-3 should be mounted on insulated or circular ducts. A test hole on
the UG-3 cover makes it easy to test the smoke detector. Simply remove the plastic
plug and spray test gas into the UG-3.
