ABS PC Red LED Emergency Exit Sign Light AC220V 50Hz With Lithium Battery

Emergency lighting

While the frequency of testing emergency equipment will be determined by the individual emergency lighting system, as a general guideline, most systems require a monthly inspection followed by a full duration test once a year.

Monthly Testing
 

This only requires a short test to check that everything is working properly. Use the test key to ensure that all emergency lights are on when the mains power is off and check the enclosures to ensure they are clean and show no signs of damage. Once mains power is restored, check that they are fully charged again.

Also most emergency lights or exit signs have a small "test" button somewhere in the housing. You can press and hold this button for thirty seconds to test the bulb and battery. This method works fine if you have a small number of devices that can be easily accessed. The light should come on and stay at the same brightness level for a full 30 seconds. If the lights dim immediately, or if some bulbs do not work, then you should contact us to replace the bulbs or batteries in the fixture.

Why thirty seconds?
 

Many defective batteries only hold enough charge to fully light the bulb for a few seconds, but they lose power quickly. If you don't test for 30 seconds, you may find lights that work every month only to find that they go out within seconds of when you really need them. By testing the lights for at least 30 seconds, you can ensure that the batteries have more than just this type of "surface charge".
