Low frequency inspection cabinet 1

Automatic fire inspection cabinet

Automatic fire inspection cabinet, also called fire intelligent digital inspection device. The device can prevent the fire pump corrosion, damp, water pump failure such action does not function properly, really do "the idea that Japan, the purpose of a way".

Chinese name

Automatic fire inspection cabinet

Also known as

Intelligent digital patrol device for fire fighting

Purpose

Prevent fire pump corrosion and moisture

Characteristic

High safety, low current, low power consumption

Necessity

According to the provisions of the Ministry of public security fire safety industry standard GA30.2 "fixed fire water supply equipment performance requirements and test methods", in order to prevent the fire pump corrosion, damp, pump action is not normal fault, really do "the idea that Japan, one day", fire pump must be installed automatic inspection device. The patrol is low frequency inspection, the speed of the motor is 300 revolutions per minute, the water system is not pressurized and no starting current, which greatly prolongs the service life of the equipment. This inspection method has high safety, low current and low power consumption. It is the only way to patrol the industry standard of the Ministry of public security.

Equipment performance

1. automatic inspection device control function: low frequency and spray pump on the fire pump and spray pump speed since the transport control inspection, inspection cycle of 24 hours, every inspection single pump inspection time is 2 minutes, inspection cycle and inspection time can be arbitrarily adjusted from minutes to days according to the actual requirements. When the fire happens, the programmable controller will automatically stop the inspection immediately after receiving the fire command, start the fire pump and end the manual shutdown.

2., equipment with sound, light alarm and memory failure function, the operation of Chinese menu clear and understandable, can remember short circuits, missing phase, over-current, over-voltage, undervoltage, communications and other faults, easy to run personnel overhaul operations.

Performance specification

Fire intelligent digital inspection device, the equipment has the main loop inspection and fire equipment, non pressure inspection of two parts, can complete the main control loop and water pump low frequency automatic inspection, inspection system is not pressurized. During the inspection, the intelligent patrol controller outputs the instruction, the intelligent patrol controller outputs the inspection instruction, and the main loop contactor is inspected one by one, and the return signal is taken from the main auxiliary contact of the contactor. The time value of the feedback signal is not greater than 2S. After the completion of the main circuit patrol, the inspection controller will have the next inspection instruction to the non pressure inspection device. After receiving the inspection instruction, the device will carry on the low speed non pressure inspection to the fire water pump in turn. The motor speed is low while the system does not generate hydraulic pressure. During the whole patrol process, if the equipment receives the fire command, the intelligent patrol controller will issue the instruction of stopping the inspection immediately, and start the fire-fighting pump at once, complete the fire fighting task. If the action is abnormal during the process of inspection, the controller will record the fault branch number and fault category, and send out sound and light alarm. At the same time to complete the upload of the failure (can be transferred to the fire control room or building control duty room), notify the relevant duty personnel to carry out maintenance, to ensure that fire fighting equipment is foolproof.

Product features

1. when fire occurs during patrol, the patrol will be stopped immediately and fire pump will be started at once.

2., complete function, can complete the fire main circuit and fire water pump low speed non pressure inspection.

3. 、 over voltage, over current, short circuit, lack of equal protection.

4. when the patrol occurs the breakdown, the automatic inspection device can produce the sound and light alarm, has the data memory function, may complete to the fault transient parameter memory, is advantageous for the maintenance, the analysis.

5. can display the patrol running parameters through the interface. (optional)

6. 、 with superior telephone alarm function. (optional)

7., equipment reserved RS485 communication interface, you can complete the automatic control of the building running status. (optional)

8. having the function of printing the fault parameters during the inspection. (optional)
