An emergency egress light is a battery or generator operated device used to provide visibility at times when main power fails within a building. Battery operated choices are most commonly implemented because they deliver increased reliability. Owners are able to ensure a visibility source is available by performing only a couple of maintenance tasks. These types of emergency egress lights occasionally require new bulbs or batteries and regular testing to guarantee availability. A form of lighting is essential for ensuring residents or occupants have a line of sight to the nearest exit during an emergency. These items must be implemented correctly and tested frequently to make certain occupants are capable of leaving a structure quickly without harm at times when an evacuation is necessary. Local codes require secondary lighting to be installed for commercial and residential structures.
The Components of Modern Backup Lighting
Modern designs consist of at least one incandescent bulb or a cluster of light-emitting diodes (LED’s) housed within a sealed beam or wedge base lamp. A reflector is used to direct their focus to a specific area and intensify the supplied amount of illumination. The reflector is typically either a type of plastic cover that is placed over the fixture or behind the illumination source. Secondary lighting can be aimed at fire exit doors or stairwell locations to show occupants the way out a structure. Each fixture has a test feature for checking operation at times when main power is still present and serves as an override button to inform the system to operate regardless of current conditions.
These systems operate at an extremely low voltage averaging between six and twelve volts to accommodate a smaller battery size and reduce circuit loads. A transformer is included in the fixture base to decrease the voltage safely as the source is switched from main power to battery operation. Batteries last for approximately ten years when they are consistently charged; however, testing is essential to make certain they will perform correctly as an unexpected disaster occurs. Regulations call for emergency egress lights along an exit path to remain lit for at least ninety minutes from the time of the outage.
Using Photoluminescent Signs and Markings to Support Installed Systems
Emergency egress lights are an important contributor to the development of a reliable safety system within a building; however, owners can do more to guarantee visibility of the nearest exit as a disaster occurs. Photoluminescent products offer a backup visual aid at times when all installed safety measures fail. While these lights have an average battery life of ten years, failure of bulbs or the battery itself is possible at any time. This type of situation leaves occupants in a dark building without a way of locating egress points such as stairwells or doors. Photoluminescent products offer an easy to install, minimal maintenance choice for creating a consistently visible exit path throughout each point of a structure. They take only a few minutes to install and are more affordable than alternative self-luminous choices. Owners will be better able to help occupants evacuate safely by implementing photoluminescent components as part of their current egress system.
