Why Emergency Light Testing?

Emergency lighting is designed to illuminate exit routes in the event of an emergency. Under Fire safety legislation, occupants in any work place or premises must be safe at all times. This fundamentally means that all buildings must, therefore, have emergency lighting schemes that are fit for purpose, should an emergency occur. Records must also be kept as proof that the required level for the duty of care has been met. 

What does Emergency Light Testing involve?

When testing an emergency lighting system, a mains power failure should be simulated. This will force the emergency lighting system to operate via the battery supply.

Different types of emergency light testing can be broken down into abbreviations such as the following:


  • M3 - Maintained, emergency duration - 3 hours

  • NM2 - Non-maintained, emergency duration - 2 hours

  • S1 - Sustained System, emergency duration - 1 hour
