Emergency lighting is comprised of lights, illuminated exit signs and combination units providing an exit sign and a lighting system. These lighting systems are designed to provide residents with illumination in the case of emergency, such as a power outage. Due to this, these systems utilize a battery, which must be fully tested on an annual basis.
The technician must run the lights, from the battery, for a period of at least 90 minutes. Upon completion of the test, a maintenance label is adhered to the side of the unit to record the date of the successful test.
