Frequently Asked Questions:
How to Choose the Right Cable for Emergency Lighting
When it comes to self-contained emergency light fittings with their own batteries, it is common to use 1.5mm2 4-core cable. This includes the following wiring:
To connect central battery emergency light fittings, it is essential to use a specific fire-resistant cable. This ensures optimal safety and reliability in emergency lighting systems.
Should emergency lighting be always on?
Emergency lighting systems should be connected to a power source at all times, but they don't need to remain illuminated constantly. Self-contained emergency light fittings, equipped with their own batteries, can be installed as either maintained or non-maintained. In maintained mode, they function like regular light fittings, being switched on and off, with an additional permanent live supply to keep the batteries charged. In non-maintained mode, these fittings are normally off and only activate during a power outage.
How can I know if the emergency lighting works well or not?
Determining the Functionality of Your Emergency Lighting
You can assess the operational status of your emergency lighting through three primary indicators:
1. Look for a green indicator LED, situated on or near each emergency light fitting. Its illumination indicates that the fitting is connected and the batteries are charging.
2. If the fitting becomes disconnected from the mains, the green LED indicator will switch off, and the fixture will rely on battery power to illuminate. This confirms proper functionality.
3. Regular testing is crucial. Conduct a brief monthly test and a comprehensive duration test (typically lasting 3 hours) at least once a year. These tests should be performed by a "Competent Person" as defined in the Regulatory Reform (Fire Safety) Order 2005. In the event of a failed test, repair the lighting or inform the "Responsible Person" accordingly.

What is the Recommended Frequency for Changing Emergency Lighting Batteries?
Emergency lighting batteries should be replaced under the following circumstances:
1. When they no longer provide the intended duration (typically 3 hours) as specified by their design.
2. When the manufacturer indicates that they have reached their end-of-life. Typically, nickel-cadmium (NiCd) and nickel metal hydride (NiMH) batteries need replacement after 3 years, while lithium batteries have a longer lifespan that varies among manufacturers.
Is it Possible to Use an Emergency Light as a Regular Light Fixture?
Absolutely. When an emergency light fixture is installed as a maintained emergency light fitting, it operates as a regular light fixture under normal circumstances. However, it seamlessly switches to emergency mode (battery operation) when the mains power fails.
Is Emergency Lighting Required in Toilets?
According to BS5226-1 regulations, emergency lighting is not necessary in toilets designed for the exclusive use of a single able-bodied person or en-suite facilities in hotel bedrooms. However, emergency lighting is required for multiple enclosed toilets without natural light and toilets designated for disabled individuals.
Do Small Offices Require Emergency Lighting?
In general, small offices may not require emergency lighting. However, if a small room can only be exited through another small room, the second room becomes the escape route for the first room, and thus, emergency lighting will be necessary for the second room.
Is Emergency Lighting Necessary for Medium-Sized Offices?
Based on BS5266-1 guidelines, a medium-sized office measuring no more than 60m2 does not require emergency lighting if it is not part of the designated escape route from the building.
What are the appropriate locations for installing emergency lighting?
Installation of emergency lighting is mandatory in nearly all public and employee-occupied buildings. Compliance is necessary under the Regulatory Reform and the Building Regulations from different countries.
