About this deal

This performs the same function as a key-switch, isolating the fitting from its permanent live supply and thereby simulating a power failure. Self-test has several benefits. First, it saves the labour of manual testing. Secondly, it removes the risk that routine monthly or annual testing is overlooked.

L SW is the normal mains supply. A normal light switch, or sensor, would usually be on this circuit to enable the end-user to have control over the light fitting in normal operating mode. L SW is always to be wired so that any switching of L PERM will disconnect L SW too, but any switching of L SW will not affect L PERM.The frequency in which you should get your emergency lighting tested can vary depending on system type (i.e. maintained emergency lighting or non-maintained), but as a general guide, you should aim to get your emergency lighting system tested monthly, in addition to an annual ‘full duration’ test as described in BS 5266-1. Emergency lighting testing requirements stipulate that emergency lighting must be maintained and regularly tested in the same way as other emergency equipment. Each light should be identified and have a location identity for recordkeeping. A record log can then be kept of the system test, defects, any damage to the system, and remedial action relating to each light. First and foremost, your emergency lighting must be tested by a competent person due to the important nature of the system in ensuring occupant safety in the event of an emergency.

There are three widely used ways to test emergency lighting. To understand them it is necessary to understand first how an emergency light fitting is wired. Note that the remarks that follow apply to self-contained emergency fittings, not to central battery operated emergency fittings.L PERM is the permanent live supply and must have no normal (manually operated) switch or sensor on it. However, a key-switch is permissible and will usually be installed on this circuit. L PERM has two functions: Here at the Fire Protection Association, we offer a 5-day Fire Detection, Alarms, and Emergency Lighting training course that provides a comprehensive understanding of systems, legislation, and standards including BS 5266-1 and BS 5839, as well as practical guidance for carrying out installation, commissioning, and maintenance of systems. Find out more here. Emergency lighting is required in premises to enable occupants to escape safely in an emergency situation. BS 5266-1 states that a building must have adequate illumination to support escape and identify firefighting equipment (or any other fire safety equipment). Areas in which there is moving machinery or vehicles, flammable materials or control rooms associated with potentially dangerous processes have, as ‘high risk task areas’, slightly different requirements in relation to emergency lighting – particularly in relation to the illuminance levels to be maintained and duration of operation. High risk task area lighting is provided predominantly to ensure that processes can be safely terminated, and occupants make their evacuation from the area without undue risk from the process. When zero voltage is detected at L PERM it is the indication to the emergency module in the light fitting that mains power has been lost and that battery power must now be switched on.
