Fire-fighting linkage of EPS power supply means that the linkage operation console set in the fire control center is directly connected to the dry contact of the EPS power supply through the DC24V control line. When the DC24V control voltage is sent out, it is the EPS power supply emergency inverter output power supply status. When disconnected, The state of the EPS power supply is such that the daily operation of the EPS power supply can be controlled in the fire control room.

The fire-fighting linkage requires that the emergency lighting type EPS power supply should have the function of one-way reception/realization of linkage control, and the EPS power supply for the fire-fighting water pump, fire-fighting elevator, and fire shutter door is generally in the same building as the linkage operation console, and the distance is generally Not more than 50m. This is not the same as computer network remote monitoring.
The design of lighting-type EPS power fire fighting linkages generally has three different ways:
1. Total output linkage design method;
2. Inverter output linkage design method;
3. The cold start linkage design method, but the purpose is only one, that is to achieve the purpose of emergency power output operation of the EPS power supply in the fire control room through the linkage console.
