Why are fire emergency lights two-headed ?
Double-headed emergency lights are common in the market, but why are double-headed emergency lights?
So let's do that for you.
The double-headed emergency light is normally connected to the mains, which means it is always ready to respond to emergency situations and will automatically turn on in case of malfunction or abnormality.
Double - end emergency lights have batteries, in the state of the accident lighting is dependent on the discharge of batteries.
Because emergency lights only work in emergency situations, they are almost always charged in normal times.
In order to prevent the battery from overcharging and ensure the normal use of emergency lights, users of emergency lights are required to carry out a complete discharge of emergency lights every month.
And record the discharge time, when the discharge time is less than 30 minutes, it is necessary to replace the emergency lights.
Right pull fire emergency lights, the price of beauty quality, worth you have!
