Fire emergency light wiring

Wiring
Dedicated lines should be set up for each emergency lighting fixture, and no switch should be set in the middle. Two-wire and three-wire emergency lamps can be unified on a dedicated power supply. The setting of each special power supply should be combined with the corresponding fire protection regulations. If the emergency power supply and the lamps are rotated separately, the electrical connection should be made of high temperature resistant wires to meet the fire protection requirements.

two-wire system
This connection method is a common connection method for special emergency lamps. It is suitable for emergency lamps that are not usually used for lighting or are used for 24-hour continuous lighting (CED sign lamps belong to this type). After the power is cut off, the emergency lamps are automatically turned on.
three-wire system
The connection method is a common connection method for emergency lights, which can control the opening or closing of the emergency lighting in the usual lighting state. K is the usual lighting switch.
