Expert Automatic Door Repair in Hounslow
In the bustling commercial environment of Hounslow, a functional automatic door is essential for footfall and security. As independent specialists, we work on all major brands including Dorma, Record, Geze, and Assa Abloy.
Brushless DC Motor Diagnostics
The drive unit is the heart of your system. In Hounslow, we troubleshoot high-torque DC motors, replacing worn carbon brushes or faulty encoders to restore silent operation.
Weather Mode Programming
Winter in Hounslow is cold. We program 'Partial Open' modes (e.g., 50% width), keeping heat inside while allowing pedestrian access.
Fire Alarm Interface
We verify the link between your door and the building fire panel. In Hounslow, the door must 'Fail Safe' (open fully) immediately when the alarm sounds.
Manual Breakout Testing
For sliding doors on escape routes, we test the 'Green Box' breakout. We ensure Hounslow staff can push the doors open manually in an emergency.
Besam & Entrematic Service
We specialize in legacy Besam UniSlide parts. We stock tensioners and belts for these common units in Hounslow.
