Secondary Deadlock for Aluminium Doors in Cambridge

Cambridge is on the border of our regular call-out patch but, for specialist work, we don’t mind taking a trip further afield. In this instance, a pair of aluminium doors had caused a technical problem that needed an expert fix. So, the owner of the property called us in.

Power Failure

The pictured aluminium doors were originally operated solely by access control – which was fine as long as there was power. During a power cut, it was realised that two doors on the building could not be secured! The answer was to install a secondary deadlock that could be operated manually in the event of a power cut.
