In daily supervision and inspection, it was found that it is common for emergency lighting fixtures to not function properly due to incorrect wiring methods. Each emergency lighting fixture should be equipped with a dedicated circuit and no switches should be set midway. Two wire and three wire emergency lighting fixtures can be unified on a dedicated power supply. The setting of each dedicated power supply should be combined with corresponding fire protection regulations. If the emergency power supply and lighting fixtures rotate separately, their electrical connections should use high-temperature resistant wires to meet fire protection requirements.
Two wire system
This connection method is a commonly used connection method for specialized emergency lighting fixtures, suitable for emergency lights that are not used for lighting during normal times or for 24-hour continuous lighting (LED marker lights belong to this category). After the power is cut off, the emergency lights will automatically light up.
Three wire system
The connection method is a commonly used connection method for emergency lights, which can control the normal lighting status of emergency lights on or off. When the power grid is cut off, regardless of the switch status, the emergency light will immediately turn on for emergency. K is the usual lighting switch.
