This is Bright Source LED Emergency Exit Box with a right arrow legend, ideal for use in identifying escape routes and exits in an event of an emergency. The 240v Bulkhead comes in maintained function as standard. This can be converted to non-maintained if required by removing the switch live link. Constructed from a steel base and a polycarbonate diffuser giving the fitting a IP20 rating. The fitting comes complete with a 3.6v nickel cadium battery which can be charged and a 1 year warranty honoured by LampShopOnline. Emergency Maintained means that these fittings will operate as normal light fittings. If the power fails, the emergency fittings illuminate via their battery backup. Emergency Non Maintained means that the bulkhead will remain in off mode and only illuminates once the power has been cut. This fitting can be made non maintained by making minor adjustments to the wiring (instructions included). Dimensions: L300mm x H180mm x D40mm
