Combined/Sustained: This is a light containing two lamps or more, at least one of which is operated from the emergency supply. The remaining lamps are operated from the normal supply. Self Contained Emergency Light Fitting: This is a fitting that can be maintained / non-maintained / combined in which all of the operating components are within 1m of the housing. Central Battery System: This is a system where the batteries for a number of fittings are housed in one location. Slave Fitting: This is an emergency light without its own batteries that is designed to run off a central battery sytem. Static Inverter: This is a central system which enables mains fittings to be utilized as emergency. Emergency Escape Lighting: Is to enable to see safe exit from a location in the event of failure of the supply to the normal lighting system. Escape Route Lighting: Is to enable the safe exit from a location for occupants by providing appropriate visual conditions and direction finding on escape routes and in special locations, and to ensure that fire fighting and safety equipment can be readily located and used. Open Area (Anti-Panic) Lighting: Is to reduce the likelihood of panic and to enable safe movement of occupants towards escape routes by providing appropriate visual conditions and direction finding. High Risk Task Area Lighting: Is to contribute to the safety of people involved in a potentially dangerous process or situation and to enable proper shut down procedures to be carried out for the safety of other occupants of the location.

	ROUTINE TESTING AND MAINTENANCE OF EMERGENCY LIGHTING It is very important that emergency lighting is properly tested and maintained in accordance with the manufacturer's recommendations. Below is the suggested routine testing procedure: Daily: Visually check that all maintained lamps are operating and that all system healthy indicators on central battery systems are illuminated. Check that any faults on the system are rectified and are then noted in the log book. Monthly: Check all luminaires and other emergency lighting equipment is in good condition and all lamps and fitting diffusers are clean, undamaged and the lamps are not blackened. Briefly test all emergency lighting by simulating a failure of the normal mains supply. The test should not exceed a quarter of the equipment rated duration, check all fittings work correctly. Upon restoring the mains supply check all mains healthy lamps are operating. Six monthly: Carry out testing as in the monthly test routine but test the fittings for one third of their rated duration. Annually: A full system test should be conducted by a competent service engineer including a full rated duration test of the system.
