Description

All ducts and airways in doors and walls can be protected against fire and hot smoke using Lorient intumescent air transfer grilles. However, these grilles will not prevent the passage of cold smoke which can be equally dangerous.

To address this problem Lorient has developed a smoke damper/shutter assembly for use in conjunction with Lorient intumescent air transfer grilles. The assembly comprises three slotted plates – two fixed plates sandwiching a central moving plate. The central plate is operated by a fail-safe motorised actuator. A movement of just 10mm changes the relative positions of the slots from “through flow” (top picture) to “fully closed” (bottom picture).

As most large buildings will have a significant number of air transfer grilles in various places throughout the building, the Talkback system has been designed to control up to sixteen damper/shutter assemblies from one centralised, status monitoring unit. A unique two-way communication system operates between the Damper Control and Monitor Unit (DCM) and each damper/shutter actuator connected to the system. This monitoring unit allows all the damper/shutter assemblies to be quickly and visually checked to identify and locate any defective shutters.
