Self-testing Emergency fittings have an in-built timer that automatically puts them into duration test mode every 6 months without the need to physically initiate the test. The tester must also determine the cause of any failures which often leads to complete fitting replacements instead of cheaper repairs such as replacing a battery. Results are often inaccurate –It is rarely possible to inspect every light on a premises at exactly 90 mins (30/90 mins in NZ).Can be very expensive and labour intensive to test – Requires someone to initiate and monitor the test (involves multiple laps of the site).Ability to buy the cheapest fittings available from any brand. The next step is to activate the test timer to cut the power to the emergency lighting then wait 90 mins (30/90 mins in NZ) and inspect each fitting to see if it is still running. A testing contractor should first walk the site and check that the fittings have power (check the charge light status) and replace any blackened fluorescent tubes. A manually tested system has exit and emergency lights wired to a test timer.* Activation of the test timer should not disrupt the power to the normal lighting.
