The Medinah LED Exit Emergency unit is a versatile and reliable solution for commercial lighting projects that require both an exit sign and emergency lighting in a unit. It is made of a thermoplastic housing that is resistant to both flames and corrosion, with a standard white finish. It features 2 detachable red/green 'EXIT' stencil faceplates and a solid backplate that can be used for single or double-sided applications. It features dual-color LED lights, enabling you to choose the lettering option that suits your needs. The Red/Green LED Exit Emergency Light Combo also comes with a universal mounting plate and canopy that allows for ceiling, end, or back installation. There is round plastic LED emergency lamp heads located on either side of the sign, which can be adjusted and locked at any angle in a full 360° axis. The LED Emergency Light is equipped with a 3.6-volt NiMH battery pack. These batteries can power the lights and sign for a minimum of 90 minutes per UL924 code. To test the emergency readiness of the fixture, there is a push-to-test switch located on the bottom of the exit sign housing. It also has dual primary 120-Volt or 277-Volt AC operation and is UL-listed for damp locations.
