Frequently Asked Questions - 12C Dormakaba

How do I install the Dormakaba 12C electric lock?

The lock is surface-mounted on wooden or metal doors. Connect the 12V DC power supply and follow the wiring diagram in the manual. Ensure proper alignment with the strike plate.

What is the power requirement for the 12C model?

It requires a 12V DC power supply with at least 500 mA current. Use a regulated power supply to avoid damage.

Can the lock be used in outdoor applications?

The IP44 rating makes it suitable for protected outdoor areas, but avoid direct rain or extreme weather.

Does the lock have a key override feature?

What is the difference between fail-safe and fail-secure mode?

In fail-safe mode, the lock unlocks when power is lost. In fail-secure mode, it stays locked. The 12C can be configured for either.

WIRING AND CURRENT DRAW

DIMENSIONS

DOOR LATCH POSITION

As drawn in the diagram, there should be a 1mm gap between the door latch and the front face of the strike keeper, preventing the door from creating back pressure on the strike keeper when the door is closed. This gap is important to ensure the proper functioning of the strike.
