SCM control process is introduced to achieve automatic detection monthly and fully discharge annually for LED Emergency lights. In case this automatic function can not be completed or discharge time is not enough, lamps alarm will automatically be on. Manual self-test function is also set to detect whether the lighting program is operating normally during maintenance
There are three status indicator lamps (main control, Hitch, Charging) and one testing button. All the indicator lamps are exposed so that the operation condition can be judged visually and directly.
Over-charging and over-discharging protections effectively ensure the availability and lifespan of the battery, meeting the National Fire Standards GB17945-2010.
