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. Confirmation that the emergency lighting system has been designed and installed to meet the specific requirements of the building and its occupants. The team here at Fire Trade Supplies have assembled a collection of Fish Key Emergency Lighting including F9099 grid keys (PK6), Multi-EL (3 pairs of assorted EL keys), EL key - crabtree style (PK6) as well as many more combinations which can all be found in our store. 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.

The duration that emergency lighting should stay on for depends on the relevant regulations and standards, as well as the specific requirements of the building and its occupants. However, the general requirement is that emergency lighting should remain illuminated for a minimum of 1 hour, but it may need to remain illuminated for up to 3 hours in certain circumstances. As I understand it the EL light units that (should) have LEDs on them, the LEDs are illuminated when in normal 'charging' mode but go out when in EL mode? Standby lighting enables normal activities within in building to continue in the event of a mains power failure. Standby lighting is not a legal requirement but is a facility that some buildings may need depending on the use and occupancy of the premises. This means that the emergency light fitting works with the main lights and is connected to the other lights and is controlled with the normal lighting. When the power fails, the emergency light remains on through the battery which has been charged whilst the mains is on. It can also be turned off whilst the mains is on if it is not needed. The battery often emits around 10% of the normal light levels. Non-Maintained Emergency Lighting Non-domestic properties have a statutory responsibility to supply, test, and maintain emergency lighting systems. The reason for the regulations is to promote safety should the power supply go down for any reason. In such an event, emergency lighting provides illumination for safe evacuation or manoeuvre around the building’s interior. It can also support operational continuity in some contexts.There are different ways to test emergency lighting in the UK, depending on the type of emergency lighting system and the requirements of the relevant regulations and standards. However, the following is a general procedure for testing emergency lighting: The name of the person or organization responsible for the maintenance and testing of the emergency lighting system. If you have a central battery system, then most of the above still applies to you. Drop the incoming power to the battery and do the same walk tests. Make a note of any failures etc. However you need to test the whole system all at once. By testing the whole system at once, you are ensuring that the battery can power all the emergency lights for a full 3 hour duration. If you only tested in zones then the battery would not get a full and proper test.

High risk task area lighting provides light for the safety of people involved in potentially dangerous processes. This lighting enables proper shut-down procedures to be followed for the safety of the operator and other occupants of a building. Records of all testing and maintenance carried out on the emergency lighting system, including dates, results, and any faults or issues identified. Simulate a power failure by either an emergency key switch or by switching off the mains power to the emergency lighting.

There are different types of emergency lighting; it can be maintained, non-maintained, or combined. Often there are choices with how long they remain on after a power failure. Maintained Emergency Lighting These professionals can advise on the steps that need to be taken to determine the extent and details of the emergency lighting system within a particular building. Simple system would be you switch the main lights on as normal, then operate the test key switch which simulates a power cut - so you can visually see the EL works. Details of the emergency lighting system, including its location, components, and the type of system installed.
