The relationship between the fire control room and the fire hydrant activation button is related to the starting method of the fire hydrant pump. There are generally two starting methods for fire hydrant pumps. The first method, under a bus-based control system, involves the hydrant activation button sending its required activation signal to the fire control room control panel via a linkage interface module located next to the hydrant. From there, a switch contact is output to activate the hydrant. The second method directly outputs the switch contact of the hydrant activation button to the fire hydrant pump starter box. Both methods can be used in practical designs. The first method requires less wiring but necessitates address coding programming of the fire hydrant linkage module under a bus system to monitor a large number of hydrants. The second method is simpler and more reliable, but it still requires sending the hydrant activation signal back to the fire control room. Designers can choose the method based on the actual project scale. Larger projects with complex building structures may use the first method, while smaller projects may use the second.
The sprinkler pumps are automatically started by the high-temperature explosion of the glass bulbs in the nozzles of the pipe network in each protected area, which causes water flow in the pipe network. This triggers the alarm valve pressure switch, thus activating the sprinkler pumps. The signal is transmitted to the control room via a water flow indicator linkage module or the alarm valve pressure switch. The fire control room can accurately reflect the activation signal and directly control the start and stop of the sprinkler pumps.
