Technology that makes access control easier to install and operate.

Enkel Boks and U-PROX for locksmiths, installers, integrators and building owners throughout Norway.

Enkel Boks 6 Par: circuit board with relays and blue terminals

Enkel Boks

Our own wiring box for the door environment. Makes installation faster and tidier — for locksmiths, installers and projects.

Enkel Boks brings all the signals at the door — lock, reader, door contact, fire signal and elbow switch — together in one labelled place, following a fixed setup.

Instead of wiring each door from scratch, the fitter follows a ready-made diagram. This makes installation faster and troubleshooting easier — and means the next person who opens the cabinet understands how the door is wired.

Easy installation

From 15–20 hours to around 7.5 hours per door.

In an office building with 12 doors we used 90 hours in total – without pulling a single metre of new cable.

Without a ready-made wiring box we estimate 15–20 hours per door for a comparable door environment.

The actual time saved depends on the door environment and the installer.

Fewer errors

Everything is carefully labelled and thoroughly tested. You avoid mix-ups between the night lock, elbow switch and function input – the faults we find most often when troubleshooting. The wiring diagram and data sheet are available to download, so the next installer can see how the door is wired without having to work it out with a meter.

Maintenance without the headache

Standardised solutions and clear labelling. No hidden connections or creative shortcuts. You get a system that is easy to understand – and just as easy to maintain, even many years after installation.

We always start by looking at what can be reused — often the existing cabling and locks can be kept, so the upgrade is faster and cheaper than a full replacement.
