A typical management regime includes regular short functional tests and a periodic full-duration test. The exact test method and duration depend on the installed system, so the building's documentation and competent maintenance advice should be followed.
Routine functional checks
Short functional tests are used to confirm that emergency luminaires operate when the normal lighting supply is simulated as having failed. Many systems are managed with a monthly function test, provided the test method does not create unnecessary risk.
Full-duration testing
A full-duration test checks whether the batteries can support the fittings for their intended emergency period. This is commonly undertaken annually, but the correct duration should match the system design and installed equipment rather than being assumed from the building type alone.
Plan for the recharge period
After a full-duration discharge, batteries need time to recharge. Testing should therefore be planned so that the premises are not left without effective emergency lighting while the batteries recover.
Record failures and remedial work
The test record should identify failed fittings, battery issues and any remedial work required. Completion evidence should then be retained so the same defect does not remain unresolved through successive inspections.
Check whether the system still suits the premises
Changes to internal layout, final exits, escape routes, occupancy or use can affect where emergency lighting is required. A compliant-looking maintenance record does not prove that the system layout remains suitable after material building changes.
