The ’emergency lighting block,’ commonly referred to as a safety light, is designed to facilitate building evacuation in case of emergencies, such as fires. It also serves as a supplementary lighting source in passageways (corridors, stairwells, halls, etc.) in the event of a power outage affecting all or part of the electrical system, allowing people to move safely without the risk of accidents.
In the overall diagram, there is only one lighting circuit supplying power to the Autonomous Lighting and Safety Blocks (ALSBs). To facilitate maintenance, a remote control device should be installed, enabling remote activation and deactivation of the ALSBs. All ALSBs are connected to it using two remote control wires (+ and -), typically colored black. When cables are used instead of wires with ICT sheathing, the ALSBs will be powered with 5G1.5 cables. The power connections are brown and blue, the remote control connections are black (+) and gray (-), and the green/yellow wire is not to be connected (for Class II devices).
General diagram, multiple lighting circuits supplied
The remote control will be the same for all lighting circuits requiring the use of ALSBs.
Example of application
Installation of ALSBs in a stairwell, where the lighting is controlled by a relay and push buttons.
