Emergency lighting test keys **Engineers pack** Emergency Light Test Keys X5

Product Information

A minimum duration of 3 hours should be used for emergency escape lighting if the premises are not evacuated immediately. The 3 hour time frame allows the fire brigade time to work in the event of a fire after all of the building’s occupants have been safely evacuated. How often should my emergency lighting system be tested? The test keys are also available in different shapes and sizes, depending on the type of switch they are designed to operate. 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. UK fire safety legislation states that emergency lighting is required in buildings to provide light if normal lighting fails during a fire. These tests are critical for ensuring that emergency lighting systems are functioning correctly and are ready to activate in the event of an emergency.

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. 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. Sometimes there isn’t a test key switch. If not then you have to find the consumer unit and turn off the power to the whole circuit that controls the emergency lights. Hopefully it will be marked which one it is, but it could be more than one circuit. It's important to note that specific testing procedures may vary depending on the type of emergency lighting system in your building. 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.

How to test emergency lighting?

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).

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. Emergency lighting is designed to activate automatically in the event of a power outage or emergency, making it an effective safety feature for building occupants. Are emergency lights a legal requirement? During regular testing of emergency lighting, the power supply to the lighting system is typically switched off manually. This simulates a power outage or emergency situation and triggers the emergency lighting to activate automatically. Always refer to the manufacturer's instructions and consult with a licensed electrician if you have any questions or concerns about testing emergency lighting. What do emergency lighting test keys do?During this period the light levels will be a lower level of illumination when in emergency mode and depending how long it would take you to walk the emergency lights would it be safe for the relevant persons occupying the building? Also if the building has sub circuits then each sub circuit has to be tested separately because if a sub circuit fails then that area needs to be illuminated by the emergency lighting.
