Electronic Lock

What is an electronic lock?

An electronic lock is a locking device which is powered by an electrical current. They usually have a keypad which the correct code must be entered into before the lock will open.

What happens if the batteries run down?

All electronic locks are designed to save your combination in an internal memory even if the batteries run down. Batteries are accessible from the outside of the safe and are very easy to replace by following the manufacturers instructions. Rechargeable batteries are not suitable and can cause irreparable damage to the lock itself.

Emergency Lighting Operation Types

Mains Failed


When in maintained operation an emergency light stays on at all times and stays lit for the minimum emergency duration after a mains failure.

When in non-maintained operation the emergency light will only come on in the event of a mains failure and will stay lit for the minimum emergency duration required.

Mains Operation

Ordinary lights without emergency functionality sold by us to allow you to equip all parts of a building with identically looking lights, even when some of the lights do not need to be emergency lights.

Slave Units

Slave units have no internal backup battery. In the event of a power failure, slave units are powered by a bank of batteries centrally located within a building. The operation of the slave unit (i.e. maintained/non-maintained) is reliant on the operation of the backup battery system.
