Tools & Materials

Step-by-Step

1. Assess the system – inspect existing emergency lights for faults or outdated batteries and determine installation requirements.

2. Isolate power – switch off the relevant circuit and confirm de-energisation with a multimeter.

3. Remove or repair faulty units – detach malfunctioning lights or battery packs, ensuring safe handling and disposal.

4. Install new units – securely mount emergency lights and connect wiring in compliance with current wiring regulations.

5. Reconnect and test – restore power, check that battery chargers are operating, and use a testing device to simulate a power failure.

6. Finalise installation – tidy wiring, secure fixings and label circuits accordingly.

Completion Checks

• Function test each unit by simulating a power outage to confirm they illuminate as designed.

• Verify that battery charging and backup times meet manufacturer specifications.

• Ensure all wiring is secure, free from exposed conductors and clearly labelled.

When to Call a Pro Instead

For extensive or commercial emergency lighting systems, or if there is any uncertainty regarding compliance with safety standards, it is advisable to engage a certified electrician or specialist for repairs and installation.
