24/7 Emergency Callout
Door stuck open at 3 AM? Our Theydon Bois emergency team carries universal controllers to bypass failed electronics and secure your site.
Fire Alarm Interface
We verify the link between your door and the building fire panel. In Theydon Bois, the door must 'Fail Safe' (open fully) immediately when the alarm sounds.
Swing Door Operator Tuning
We adjust latching action and backcheck on swing operators (like Record DFA 127). This ensures your Theydon Bois door closes securely against wind pressure.
Digital Selector Switch Repair
Can't change modes? We replace faulty FPC 902 programmers, allowing Theydon Bois managers to toggle 'Auto', 'Exit Only', and 'Locked' easily.
Manual Breakout Testing
For sliding doors on escape routes, we test the 'Green Box' breakout. We ensure Theydon Bois staff can push the doors open manually in an emergency.
