Ensuring safety in buildings is essential, and one of the critical elements of safety in public and commercial spaces is emergency lighting. If you’ve ever wondered about the difference between Maintained vs Non-Maintained Emergency Lights, you’re not alone. These two types of emergency lighting systems serve unique functions and are essential to meet safety standards and protect lives during a crisis. In this article, we’ll delve into everything you need to know about maintained and non-maintained emergency lights, from their definitions to their advantages and practical applications.
Understanding the Importance of Emergency Lighting Systems
Emergency lighting systems are a vital component in any building’s safety plan. In the event of a power failure or emergency, they guide people to exits, prevent panic, and ensure that critical areas are still illuminated. These lights provide visibility in stairwells, corridors, and other key parts of a building during an emergency. Understanding the types of emergency lighting is crucial to ensuring that your building complies with legal requirements and provides a safe environment for all occupants.
What are Maintained Emergency Lights?
Definition of Maintained Emergency Lights
Maintained emergency lights are a type of emergency lighting system that remains switched on at all times, whether the main power is working or not. In other words, they function as regular lighting but switch to battery power in case of an electrical failure.
How Maintained Emergency Lights Function
Maintained lights are wired into the normal electrical system but have a backup power supply—usually a battery. When the mains power is cut off, these lights automatically switch to battery power, ensuring that the area remains lit. This makes them ideal for locations where lighting is needed both during regular operation and emergencies.
Common Uses for Maintained Emergency Lights
Maintained emergency lights are commonly found in spaces where continuous illumination is required.
Commercial Buildings
In large office complexes, maintained lights ensure that hallways, lobbies, and workspaces remain lit, even during power outages. This is crucial for ensuring a safe evacuation process.
Public Spaces
Museums, theaters, and concert venues often use maintained emergency lights to ensure visibility during performances or exhibitions and in case of emergency.
What are Non-Maintained Emergency Lights?
Definition of Non-Maintained Emergency Lights
Unlike maintained emergency lights, non-maintained lights are only activated during a power outage. They remain off during normal operation and switch on when the main power fails.
How Non-Maintained Emergency Lights Function
Non-maintained lights are equipped with a battery backup system. When the primary power supply is cut off, the emergency lights are triggered, providing illumination for escape routes, exits, and other critical areas.
Typical Applications of Non-Maintained Emergency Lights
These lights are typically used in environments where emergency lighting is not needed during normal operations.
Industrial Environments
Non-maintained emergency lights are common in factories and warehouses, where normal lighting is sufficient during working hours but emergency lighting is critical during power failures.
Escape Routes and Fire Exits
Non-maintained emergency lights are crucial for lighting up escape routes and fire exits in any building during an emergency.
Key Differences Between Maintained and Non-Maintained Emergency Lights
Power Supply and Operation
Maintained lights stay on continuously, using mains power during normal operations and battery power during outages. Non-maintained lights, on the other hand, remain off during normal operation and are only powered by the backup battery during emergencies.
Energy Consumption
Maintained lights tend to use more energy because they are always on, while non-maintained lights are more energy-efficient since they are only activated during power cuts.
Installation Requirements
The installation of maintained lights is more complex because they need to be wired to both the main power supply and a backup battery. Non-maintained lights require less wiring and are easier to install in comparison.
