Description
The SN-LM42DR from Alpha is a refuge assistance sign photoluminescent double, photoluminescent type can be ceiling or wall mounted has ‘area of refuge’ imprint. Photoluminescent materials absorb and store energy from normal ambient light and are designed to glow in total darkness; it then releases this energy in the form of light during an emergency.
Reliability has been an inherent problem with conventional emergency exit signs due to maintenance issues and bulb failure. The big advantage of Cornell’s ARA signs is that there are no internal lights to burn out making it almost 100% reliable and virtually maintenance free.
