Similar testing protocols are in place for these units and proper maintenance and periodic battery replacement should be considered just as essential. These are rare unless the battery is large, and the fixture is rated for extended use during emergencies.Īlthough many exit signs now utilize LED bulbs and thus only require a small NiCad battery, there are older units and current dual units with emergency lights that are part of the exit sign that use sealed lead acid batteries. Some larger batteries have L terminals, which are also used on car batteries. The fixture will be supplied with a connector that will slip over the tab on the battery to close the circuit. The typical terminal type for a sealed lead acid backup battery is a faston tab. This can cause your system to malfunction or cause damage to the lighting fixture. Never replace a 12v battery with a 6v or a 6v with a 12v. For emergency lighting using sealed lead acid batteries, the voltage is usually 6v or 12v. The emergency lighting battery must be replaced by a battery with the same voltage, dimensions and terminal type. In optimal environments emergency light batteries can last longer than the typical 4 years indicated by manufacturers, but the results of the testing should dictate replacement whether or not they reach the 4 year mark. When either the monthly test or the annual test generate unsatisfactory results, the emergency light battery needs to be replaced. Most emergency lighting units have self-test switches that provide an accurate battery reading. When the power goes out, the batteries kick in providing light to illuminate the hallways and stairs that are part of the emergency exit paths. The lights are connected to the electrical system of the building providing a constant charge to the batteries. A monthly test with the lights on for at least 30 seconds and a longer yearly test is common.Įmergency lighting and exit signage lights work in a similar fashion. There are also guidelines for how and how often to test the emergency lighting system. The emergency lighting must provide illumination for all egress routes automatically and within seconds in the event of a power failure. To mitigate that risk, your emergency lighting systems need to be ready at all times.įunctional emergency lighting, or egress lighting, is often required to meet state building codes, fire codes, insurance standards and OSHA requirements. In the event of a fire or other disaster that cuts off electricity, people and property can be at risk.
