Short Description:

When the weak current signal and the hard-pull line start pump relay failure and the secondary circuit failure and electrical failure of the fire pump control cabinet cannot cause the fire pump to start automatically or manually, so in the event of a fire emergency, this article stipulates that as long as the power supply is normal, regardless of fire If the control circuit in the pump control cabinet is damaged, the pump can be forced to start directly to ensure the timeliness of fire fighting. The “mechanical emergency start device” is a device that directly drives the fire pump through the mechanical interlocking device.
