Battery backup systems are the most common and cost-effective solution for emergency lighting. They provide a reliable source of power during emergencies and can be easily integrated into the existing electrical system. Battery backup systems typically consist of rechargeable batteries that are continuously charged when the main power supply is operational. In the event of a power outage, the batteries automatically take over, providing power to the emergency luminaires. Central Control Panel: The central control panel is responsible for monitoring and controlling the emergency lighting system. It receives signals from various sensors and detectors, such as smoke detectors or motion sensors, and activates the emergency luminaires accordingly. The central control panel can also be used to schedule regular testing and maintenance of the emergency lighting system. Modern control panels are often equipped with advanced features such as self-testing and self-diagnostic capabilities. These features help ensure the reliability and functionality of the emergency lighting system, reducing the need for manual testing and maintenance.
Legal Requirements for Emergency Lighting
In the United Kingdom, emergency lighting is regulated by the Fire Safety Order 2005 and the British Standard BS 5266-1:2016. These regulations outline the requirements for emergency lighting systems in different types of buildings and environments. It is essential for organizations to comply with these regulations to ensure the safety and well-being of everyone present within their premises.
