Telescopic Door Alignment
Telescopic doors in Norbury require precise belt synchronization. We align the slow and fast leaves to prevent jamming and ensure maximum opening width.
Manual Breakout Testing
For sliding doors on escape routes, we test the 'Green Box' breakout. We ensure Norbury staff can push the doors open manually in an emergency.
Radar Sensor Calibration
Ghost opening wastes energy. We upgrade old sensors in Norbury to digital microwave units that filter out rain and cross-traffic, only opening for genuine customers.
Battery Backup (UPS) Tests
In a power cut, your door must work. We test NiMH battery packs to ensure your door performs its emergency open/close function, a key fire safety requirement in Norbury.
