Purpose: Emergency lights serve as a backup lighting source when the main power supply fails. They help to ensure visibility, facilitate safe evacuation, and enable emergency personnel to carry out their duties effectively.
Types of Emergency Lights: There are various types of emergency lights available, including:
Exit Signs with Built-in Emergency Lights: These lights are commonly found in public buildings and indicate the nearest exit. They incorporate battery-powered lights that illuminate when the main power goes out.
Stand-Alone Emergency Lights: These lights are separate units that can be mounted on walls or ceilings. They activate automatically during a power failure and provide illumination for a specific duration.
Central Battery System: This system involves a central battery unit that powers multiple emergency lights throughout a building. It is commonly used in large buildings or complexes.
Features:
Battery Backup: Emergency lights are equipped with rechargeable batteries that automatically activate during power outages.
Duration: The duration of backup power varies depending on the type of emergency light and the capacity of its battery. It can range from 1-3 hours or more.
Self-Testing: Some emergency lights come with self-testing capabilities to ensure their proper functioning. They perform regular diagnostic tests and indicate any faults or issues.
Remote Monitoring: In certain setups, emergency lights can be remotely monitored to track their status, battery life, and any malfunctions.
Installation and Maintenance:
Emergency lights should be installed strategically, ensuring that they provide adequate illumination in critical areas, such as corridors, stairwells, and exit paths.
Regular maintenance is crucial to ensure the reliable operation of emergency lights. This includes periodic testing, battery replacements as needed, and inspection for any physical damage or obstructions.
