Test Emergency Light Units

Emergency light units provide temporary lightning in an office or building in the event of a power outage. Regular testing of the emergency light units is mandatory and helps to ensure the lights work when and if they are necessary. Testing emergency lights varies slightly among the many manufacturers. Most emergency lights have a button for quick monthly testing, while some require power interruption for annual testing. Does this Spark an idea?


1. Place a ladder or stool under the emergency light unit so you can reach the top of the unit. Look for a button switch on the top or side of the unit. The word test should be near the switch.

2. Press the button with your finger and hold it for 30 seconds. The lights on the unit should illuminate. If they do not or if they are dim, call a qualified, service technician.

3. Locate the lighting circuits for the emergency lights for annual testing. There is usually a box near the main electrical panel. Insert the test key into the box and switch the power to the “Test” position, if your emergency lights have a separate box.

4. Allow the emergency lights to illuminate for 1½ hours. If the lights do not illuminate, call a service technician.

5. Turn off the main power switch if you do not have a separate circuit for the emergency lights, or if they do not have test buttons on the individual units. Turn the main power switch off, and the emergency lights should operate if fully functional.
