Q:The fire pump control cabinet has two 3 - turn rotary switches. What is it for?

The fire pump control cabinet mostly control 2 fire pumps, 1 prepared with 1 type, manually start and stop the pump in the fire pump control panel on the operation panel with a start stop button, red stop, green boot, a switch panel, at the position in general (that is, the handle for the vertical state) to manually start and stop the pump, as the field debugging, the switch handle position in 1# pump 2# pump automatic standby for the left 45 degrees, the fire control center to start the pump signal after 1# pump operation, 1# pump fault start up, after conversion circuit switching control cabinet, the pump will automatically 2# put into operation, the switch handle position in 2# pump 1# pump automatic standby for the right 45 degrees, with the function of 1# pump, the standby pump switching function only in the switch handle in the automatic position only. The control cabinet control interface has 3 main modules, fire fire, multi line bus module, fire hydrant button (spray pump for pressure switch or electric contact pressure gauge) interface, test method of pump switching function: main switch handle to automatic position (e.g. 1# 2# automatic backup), the fire control center (or analog a signal to start the pump), 1# pump control circuit disconnect, see 2# pump can not be put into operation.

Q:What line is the centralized fire alarm controller connected to the area controller?

If it is not the same brand or can not be directly networked, the signal of the general gas fire control panel to be exchanged with the fire alarm controller is provided:Primary alarm monitoring signalTwo alarm monitoring signalPressure switch monitoring signalAlarm action control signalSound light alarm control signalThus, the signal of the main gas disk can be displayed on the fire alarm control panel.

Q:Difference between fire automatic fire alarm system and fire fighting linkage system

1. multi wire linkage control system, from the linkage controller to each linkage equipment should connect 2 -6 lines, generally applicable to less linkage equipment building. For more linkage equipment, if the use of multi line linkage control system, the construction of the project is more difficult, it is best to use the bus linkage control system.

Q:What is the problem of buzzer alarm in fire pump control cabinet?

In accordance with fire power control requirements, relays, contactors and so on, only overload, no power, this situation is mostly thermal relay, the need to adjust the current.

Q:Central fire control cabinet cabinet what Qintai GT1901

Fan fire linkage principle is very simple, that is, one or 2 (usually 2 simultaneous detection of smoke signals, one or 2 can be set by fire linkage host)

Q:What are the responsibilities of fire control room equipment operators?

The use of exclusion to determine a variety of reasons, such as detector aging, alarm problems, there are wiring problems, to see if the entire protection zone recently renovated, touched the bus circuit.

Q:What does "fire line" on the fire alarm display mean?

Multi line is probably said that a number of communications bus, or a number of communications lines, and now seems to fire only the linkage disk, multi line.

Q:How does the fire alarm turn on and off?

Fire control, communication and alarm circuit with dark laying, should use the metal tube or plastic tube to protect the flame retardant treatment, and should be laid in the structure layer burning body, and the protective layer thickness of not less than 30mm. When used for laying, metal or metal groove shall be used for protection, and fire protection measures shall be adopted on metal tubes or metal wire grooves.

Q:About the starting mode of fire water pump

Fire hydrant pump buttonFire hydrant pump button is generally installed on the fire hydrant box, press the button to control the fire pump start.
