Battery Powered Exit Signs

Battery Powered Exit Signs are a myth. By national, state, and local building codes, an exit sign's source of power cannot come from a battery alone. Nickel Cadmium Batteries, used in all GreenTorch battery-backup electrical exit signs, constantly charge while the exit sign is connected to AC or hardwired power. When power fails in an emergency situation, batteries will power the emergency lighting and illuminate for a minimum of 90 minutes, as mandated by building and fire codes across America and Canada. Our high grade nickel cadmium exit sign batteries will last for 90 minutes or more and the easy test button allows checking of functionality with the press of a finger.

OSHA requirements include testing each battery backup exit sign for 90 seconds on a monthly basis and one 90 minute test per sign annually. These tests can be done manually, or with GreenTorch Self-Testing Exit Signs. GreenTorch also carries a full line of replacement batteries, for a wide array of applications.

If an exit sign is necessary in a location where there is no electrical source, you can choose a GreenTorch non-electrical exit sign instead of running electricity to the location. Photoluminescent or glow-in-the-dark exit signs charge from surrounding light. Self luminous or nuclear exit signs are internally powered by tritium gas which does not need light or electricity to illuminate. Non-electrical exit signs last between 10 and 25 years, depending on model purchased. Both of these types of non-electrical exit signs mount easily in multiple configurations: ceiling, wall, and flag.
