GR-427/12L/MAR is self testing, maintained, emergency luminary with white LEDs which is used in ships. This luminary is permanently connected to the mains power supply and while the power is on the battery is charging and the LED strip lights continuously. In case of a mains power supply failure the LED strip will be supplied by battery and will light continuously. The advantage of this emergency luminary is the self-testing function that measures battery's back up power and checks the functionality of Led strip and the supplying circuit. This check can be held manually too. During manual test all indication LEDs are off.
The minimum autonomous duration of the integrated battery is 8 hours. The viewing distance for these luminaries is 20 meters.
This luminary, according to Lloyd's Register Type Approval System, is suitable for marine and offshore applications for use in environmental categories ENV1, ENV2, ENV3 & ENV4, where ENV1 are controlled environments, ENV2 are enclosed spaces subject to temperature, humidity and vibration, ENV3 are enclosed spaces subject to generated heat from other equipment and ENV4 are mounted on reciprocating machinery.
