                                                         Product Standards

"Performance requirements and test methods for fixed fire service water supply equipment - Part 1: Fire pressure water supply equipment" GA 30.1-2002
                                                         Product advantages

1) Start-up mode: The device has automatic, manual and long-distance fire linkage three control methods, the device can start emergency fire button to start, but also by the fire center remote start. Frequency counter with a fire start and stop signal interface, the device received a fire signal, immediately enter the fire water supply status, a pump failure or flow is not enough, the automatic frequency can move another pump. Fire signal release, immediately restored to normal fire control status. In order to prevent automatic frequency in case of failure, the system also has a manual power frequency start function.

2) Regulating function: When the inverter cabinet has no fire signal in automatic mode, the equipment is in working state of frequency conversion and voltage regulation, and the water pressure limit signal of the pipe network is collected by the pressure gauge. When the water pressure in the pipe network drops to the lower limit of the regulation voltage, Operation, to the fire hydrant network, when the pipe network pressure reaches the pressure limit, the fire pump to stop running, this time by the pressure tank to pipe network recharge regulator.

3) Automatic pump change function: The fire main pump has the function of cyclical rotation operation, and the pump change period is set by the frequency counter program, generally set to 24 hours. If the device detects a pump failure, immediately switch to another pump steady operation and alarm display.

4) Automatic (manual) inspection function: Although the fire pump pump is usually the normal operation of the pump, but the regular inspection of the pump is still very necessary to prevent accidents caused by long-term pump does not run and "rusty." Inspection cycle and inspection run time set by the program. If the inspection pump failure, the system can automatically alarm.

5) Intelligent fire fighting function: due to fire or pipe network serious water leakage, in the absence of fire signal, the device automatically enter the fire high water supply, and alarm.

7) A variety of protection and fault alarm function: The system has off phase, overload, ground, undervoltage protection and alarm functions.

8) Control Interface: The system has a water level interface for water shortage alarm indication. In addition there is also linked with the fire center linkage, feedback interface, to achieve long-distance automatic start and pump health feedback. According to the requirements can provide standard RS485 communication interface, easy to remote monitoring.

9) Can be equipped with dual power switching device, when the main power fails, it can automatically switch backup power.
