How to troubleshoot emergency exit light issues

Emergency exit lights are a crucial component of any building's safety system. They provide illumination when power is lost, guiding occupants to the nearest exit in case of an emergency. However, like any other lighting fixture, emergency exit lights can encounter issues that may hinder their functionality. In this blog post, we will discuss how to troubleshoot common emergency exit light issues to ensure your building's safety measures are not compromised.

One of the most common issues with emergency exit lights is dim or flickering illumination. This can be caused by a variety of factors, including a faulty bulb, corroded connections, or a battery that needs to be replaced. To troubleshoot this issue, start by checking the bulb in the exit light fixture. If the bulb appears to be burned out or damaged, replace it with a new one of the same wattage and type. Additionally, inspect the connections in the fixture for any signs of corrosion or damage. Clean or replace any corroded connections to ensure a proper electrical connection.

If the bulb and connections appear to be in good condition, the issue may lie with the battery powering the emergency exit light. Most exit lights are equipped with rechargeable batteries that need to be replaced every few years to maintain proper functionality. Consult the manufacturer's instructions for the recommended battery replacement schedule and procedure. Once the battery has been replaced, test the emergency exit light to ensure it is operating correctly.

Another common issue with emergency exit lights is a complete lack of illumination when the power is lost. This could be due to a blown fuse, a tripped circuit breaker, or a faulty wiring connection. To troubleshoot this issue, start by checking the fuse or circuit breaker that controls the power to the exit light. If the fuse is blown or the circuit breaker is tripped, replace the fuse or reset the circuit breaker to restore power to the exit light.

If the fuse and circuit breaker are both functioning properly, the issue may be with the wiring connections to the exit light. Inspect the wiring for any signs of damage or disconnection, and repair or replace any damaged wiring as needed. Once the wiring connections have been inspected and repaired, test the emergency exit light to ensure it is receiving power and illuminating properly.

In some cases, emergency exit lights may emit a buzzing or humming noise when powered on. This could be caused by a faulty ballast, loose wiring connections, or improper grounding. To troubleshoot this issue, start by inspecting the ballast in the exit light fixture. If the ballast appears to be damaged or malfunctioning, replace it with a new one of the same type and wattage.

Additionally, check the wiring connections in the fixture for any signs of looseness or damage. Tighten any loose connections and repair or replace any damaged wiring to eliminate the buzzing or humming noise. Finally, ensure that the exit light fixture is properly grounded to prevent electrical issues and noise interference.

Overall, troubleshooting emergency exit light issues requires attention to detail, knowledge of electrical systems, and a commitment to safety. By following these tips and techniques, you can identify and resolve common exit light issues to ensure your building's safety measures are functioning properly. If you encounter a more complex issue or are unsure of how to troubleshoot a problem, it is always best to consult a qualified electrician or safety professional for assistance. Remember, the safety of building occupants relies on the proper functionality of emergency exit lights, so it is important to address any issues promptly and effectively.
