How to Test Emergency Lights

Emergency lights play a critical role in ensuring safety during power outages or other emergency situations. Properly functioning emergency lights, including emergency exit lights, provide clear visibility and direction to exits, helping to prevent panic and facilitate safe evacuation. Regular testing of these lights is essential to ensure the work effectively when needed. This article will guide you through the process of testing emergency lights, with a particular focus on emergency light batteries.

Why Test Emergency Lights?

Testing emergency lights is crucial for several reasons:

Safety: Ensuring the lights function properly during an emergency can save lives.

● Compliance: Many jurisdictions require regular testing of emergency lighting systems to comply with safety regulations.

● Maintenance: Regular testing helps identify and rectify issues before they become critical.

Types of Emergency Lights

Before diving into the testing process, it’s important to understand the different types of emergency lights:

● Standard Emergency Lights: These lights automatically turn on when the main power supply fails.

● Emergency Exit Lights: These lights not only illuminate but also indicate the direction of exits.

● Combination Units: These units include both an emergency light and an exit sign in one fixture.

Testing Frequency

The frequency of testing emergency lights depends on various factors including local regulations and manufacturer recommendations. Generally, the following schedule is recommended:

● Monthly: Conduct a quick functional test.

● Annually: Perform a full duration test to ensure the lights can run for the specified period, usually 90 minutes.

Tools and Equipment Needed

To test emergency lights, you’ll need the following tools and equipment:

● Test Button: Most emergency lights come with a built-in test button.

● Multimeter: For checking the voltage of emergency light batteries.

● Stopwatch: To time the duration of the lights during a full test.

● Replacement Batteries and Bulbs: In case the existing ones are faulty.

Steps to Test Emergency Lights

Monthly Functional Test

● Locate the Test Button: Find the test button on the emergency light fixture.

● Press the Test Button: Press and hold the test button. The emergency light should illuminate.

● Observe the Light: Ensure that the light comes on and remains bright. If the light flickers or is dim, the battery might be weak or the bulb could be failing.

● Release the Button: Once released, the light should turn off, indicating that it’s operating correctly in its automatic mode.

● Record the Results: Keep a log of the test results, noting any issues for further investigation.

Annual Full Duration Test

● Turn Off the Power Supply: Cut the main power supply to the emergency lights. This simulates a power outage.

● Start the Stopwatch: Begin timing the duration as soon as the lights come on.

● Monitor the Lights: Watch the lights for the entire duration (typically 90 minutes). They should remain bright and not flicker.

● Check Battery Voltage: Use a multimeter to check the battery voltage before and after the test. A significant drop in voltage might indicate a failing battery.

● End the Test: Restore the main power supply and ensure the emergency lights return to their charging state.

● Inspect the Lights and Batteries: Check for any physical damage or signs of wear. Replace any faulty batteries or bulbs.

● Record the Results: Log the duration of the test and any maintenance performed.

Testing Emergency Exit Lights

Emergency exit lights are vital for guiding people to safety. Here’s how to test them:

● Visual Inspection: Ensure the exit lights are clearly visible and not obstructed.

● Functional Test: Press the test button. The exit sign should illuminate, clearly indicating the direction of the exit.

● Full Duration Test: Similar to other emergency lights, perform a full duration test annually. Ensure the exit light remains illuminated for the specified period.

● Battery Check: Use a multimeter to test the battery voltage. Replace the battery if it’s below the recommended voltage level.

Maintenance Tips

● Regular Cleaning: Dust and dirt can obscure the light, reducing its effectiveness. Clean the fixtures regularly.

● Battery Replacement: Emergency light batteries typically need replacement every 3-5 years. Check manufacturer recommendations.

● Bulb Replacement: If the light is dim or flickering, replace the bulb immediately.

Common Issues and Troubleshooting

● Light Doesn’t Turn On: Check the bulb and battery. Ensure the connections are secure.

● Light is Dim: This could indicate a failing battery or an old bulb. Replace as necessary.

● Flickering Light: Check for loose connections or a failing bulb. Ensure the battery is properly connected.

● Short Duration: If the light doesn’t last for the required duration, the battery might need replacement.
