How to check the working status of bulkhead emergency lights?

Confirm the power connection of the light. Bulkhead emergency lights generally rely on both mains power and internal batteries. Check that the power connection of the light is intact, ensuring that the power plug and socket are not loose or corroded, and the wires are not frayed or damaged. If the emergency light is operated by the mains power, the light should automatically switch to battery mode when the main power is disconnected.
Check the condition of the batteries. Most emergency lights are equipped with batteries as a backup power source, so the health of the batteries is critical. Many bulkhead emergency lights are equipped with a battery power indicator, usually with an LED light or a digital display to indicate the battery power level. If the battery power is low, the light may not provide sufficient lighting. When checking, check whether the battery indicator light is on and confirm that it shows the "full" status. If the battery power is low or the indicator light is flashing red, it means that the battery needs to be charged or replaced.
The working status of the emergency light can be further confirmed by simulating a power outage test. Disconnect the main power or artificially simulate a power outage to ensure that the emergency light can automatically start and maintain lighting. This is the most direct and effective way to check the emergency light. If the light does not work properly after a power outage, it may be a battery failure, a control system problem, or a problem with the power switching mechanism. In this case, the lamp must be maintained or the battery replaced.
Many modern emergency lights are equipped with a self-test function that automatically checks the working condition of the lamp at regular intervals. This function is usually performed automatically at a predetermined time every day, week or month to ensure that the emergency light can still work normally when it is not used for a long time. The self-test function detects the battery power of the lamp and the status of the bulb or LED light through the internal circuit. If an abnormality occurs, it will usually issue a warning through an indicator light or an alarm system. Regularly check whether there is a self-test indication and confirm that the self-test results are normal to avoid potential faults in the emergency light.
During the self-test process, some bulkhead emergency lights may flash an indicator light or emit an audible prompt to indicate the battery charge status or the working status of the lamp. Through these indicators, users can easily understand whether the lamp is in normal working condition. If the self-test function fails to indicate normal status, it is recommended to manually check the various components of the lamp to ensure that it can start smoothly.
In addition to these regular inspection steps, maintenance of bulkhead emergency lights also includes regular replacement of batteries or LED modules. In some cases, even if there is no obvious fault in the lamp itself, the battery will age due to long-term use, resulting in a decrease in its energy storage capacity. Therefore, regularly replacing batteries or performing maintenance according to the recommended cycles in the product manual can ensure that the lamp is always in optimal working condition.
