Fire pump is the equipment to provide power water for the water fire extinguishing system pipeline in the building, if a fire occurs, the fire pump can not start normally, the fire fighting system will not be able to run, which means there is a possibility of missing the best time to put out the fire, the consequences can be imagined. Fire pump good operation, starting equipment is the key. The fire pump start control mode is divided into automatic start, manual start, mechanical emergency control.

First, automatic control
Automatic start is generally divided into chain start pump and linkage start pump, chain start is based on the alarm valve on the pressure switch, high fire water tank on the flow switch, low pressure switch on the main network, etc. This signal only one way signal can be directly chain start fire pump.
In addition, linkage start pump is through the automatic fire alarm controller pre-designed logical relationship, linkage start fire pump, such as setting a temperature sensor and the two-way signal linkage start fire pump such as hand or fire alarm.
Second, manual control
Manual start refers to the manual operation by human to start the fire pump. Manual start is generally divided into three ways.
One is to use the pump control cabinet on the start-stop button to manually start and stop the fire pump, the second is to use the fire alarm controller multi-line disk or bus disk directly manually start the fire pump. The third is to use the pump control cabinet on the forced start-stop button. This function is mainly used for control and emergency control during maintenance.
Third, mechanical emergency control
Mechanical emergency control is to start the fire pump when the above automatic and manual start is invalid. When the control line, relay and other equipment are damaged, as long as the power supply of fire pump is normal, the mechanical emergency device should be able to guarantee to start the pump.
