Talkback Damper Control System
Air Transfer Grilles
The “Talkback” system has been designed to provide up to 16 damper/air transfer grille locations with one centralised status monitoring location. The unique 2-way communication system between the Damper Control & Monitor Unit (DCM) + the damper actuators facilitates rapid assessment of serviceability of the installation + immediately identifies the location of a defective damper.
