Duct smoke detector UG-3-A4
_____________________________________________
If the air inlet is not at the roof level, in the inlet duct or directly near the air supply ducts, a
smoke detector for automatic deactivation of the pressure differential system should be provided in
case when large volumes of smoke are present in the supplied air.
If the air inlets are at the roof level, two air inlets are required (two intake vents configuration).
Each inlet must be protected by an independent damper system with a duct smoke detector installed
upstream.
