All emergency lighting fixtures should be equipped with dedicated lines, and no switches should be installed in the middle. Two-wire and three-wire emergency lamps can be unified on a dedicated power supply. The setting of each dedicated power supply should be combined with the corresponding fire protection regulations. If the emergency power supply rotates separately from the lamp, the electrical connection of the automatic emergency lamp shall adopt high-temperature resistant wires to meet the fire protection requirements. Below, Jump Start Manufacturers will introduce the commonly used wiring methods for emergency lighting:
Precautions for three-wire wiring:
1. The characteristics of various wiring methods must be accurately mastered, so as to avoid blind wiring and fail to play its due role.
2. If emergency lighting is used as part of usual lighting, the three-wire controllable connection should be adopted.
3. For projects with fire control and management areas, in order to meet the requirements for fire fighting and emergency lighting on fire floors and related floors when a fire occurs.
4. For multi-story public buildings, if there is no anti-control area, the emergency lighting fixtures in each part can be controlled by adding local switches (single lamp single control or multi-lamp control) or centralized control in the distribution box three-wire connection method.
Precautions for two-wire wiring:
The connection method is a commonly used connection method for emergency lights, which can control the on or off of the usual lighting state of emergency lights. When the power grid is cut off, no matter what state the switch is in, the emergency lights will immediately light up for an emergency.
