Maintained Operation

When in maintained operation the lamp of an emergency luminaire stays on constantly at all times and stays lit for the minimum emergency duration after a mains failure. Maintained lights can be wired to a light switch to be used as normal room lighting and will function as emergency lighting during a mains power failure even when switched off.

Non-Maintained Operation

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

Please Note: Maintained units are capable of being wired to enable non-maintained operation.

Mains Operation

Mains operated units are designed to be wired into a local power circuit for general lighting and do not have emergency functionality. They are available for purchase to facilitate installation of the same style fittings throughout an entire premises.

Slave Units

Slave fittings have no internal backup battery and must be wired into a dedicated power circuit. In the event of a power failure, slave units are powered by a bank of larger batteries centrally located within the premises. The operation of the slave unit (i.e. maintained/non-maintained) is reliant on the operation of the backup battery system.
