When it comes to emergency lighting, understanding the difference between maintained and non-maintained systems is crucial for ensuring safety and compliance. Here’s a breakdown to help you decide which type is best for your building.
Maintained Emergency Lighting
Maintained emergency lights are designed to be on at all times. These lights are integrated into the regular lighting system and remain illuminated during normal operation. In the event of a power failure, they continue to provide light, powered by a backup battery. This type of lighting is commonly used in public venues such as cinemas, theatres, and shopping centres, where the lights need to be visible even when the main lighting is dimmed.
Key Features:
- Always on, even during normal operation.
- Provides continuous illumination during power failures.
- Ideal for public spaces where lighting is often dimmed.
Non-Maintained Emergency Lighting
Non-maintained emergency lights, on the other hand, are designed to activate only when the main power supply fails. These lights are powered by a battery that is kept charged by a trickle of mains power. They are typically used in workplaces, offices, and schools, where the building is usually well-lit during occupancy.
Key Features:
- Activates only during power failures.
- Battery-powered with a trickle charge from mains power.
- Suitable for workplaces and buildings with consistent lighting.
Dual-Mode Emergency Lighting
Some emergency light fittings can operate in both maintained and non-maintained modes. These switchable units offer flexibility, allowing a single type of light to be used in various settings. This is particularly useful for buildings with multiple uses, ensuring compliance with safety regulations without the need for different types of lighting.
Making the Right Choice
Choosing between maintained and non-maintained emergency lighting depends on the specific needs of your building and its occupants. Conducting a fire risk assessment with a competent person can help determine the most suitable option. This assessment will ensure that your emergency lighting system meets current regulations and provides adequate safety for all occupants.
By understanding the differences and applications of maintained and non-maintained emergency lighting, you can make an informed decision that enhances safety and compliance in your building.
