Top Quality DF518S Rechargeable Emergency LED Driver for 3-40W Downlight with Self-test
Self-test Function
1.Building owners should be aware of routine testing of emergency lighting. The testing can be either a manual inspection or automatic testing.
2.Self-test emergency lighting is a type of lighting system that automatically checks its functionality and performance on a regular basis. It is designed to ensure that the emergency lights are always operational and ready to provide illumination during power outages or emergencies.
3.The self-testing feature of these lights eliminates the need for manual testing, which can be time-consuming and most importantly, prone to human error. Instead, the lights perform automated tests to verify their battery capacity, lamp functionality, and overall performance. These tests are conducted at regular intervals, such as weekly or monthly, depending on the specific regulations and guidelines in place.
4.During the self-test, the emergency lights simulate a power outage or emergency situation to assess their response. They may dim or switch off momentarily to mimic a loss of power and then restore to full brightness once the test is complete. If any issues are detected, such as a low battery etc., the lights will indicate a warning or alert, allowing for timely maintenance and repairs.
