自动消防水炮灭火装置 系统工作原理: Working principle of automatic fire water monitor system:

自动消防水炮灭火装置 可以全天候探测保护范围内的一切火情。 ZDMS0.8 / 20S-ZQ automatic fire water cannon fire extinguishing device can detect all fire conditions within the protection range 24/7. In the event of a fire, the fire extinguishing device will immediately detect and quickly locate the source of the fire, and then intelligently open the solenoid valve and output a signal to the on-site control box to start the water pump and spray water by the water nozzle. After one cycle of water spraying (the cycle time can be reasonably adjusted according to the site's needs), the system will intelligently stop the water spraying and the nozzle will automatically reset. If there is a new fire source, the system will intelligently repeat the above actions until the fire is completely cleared. The on-site control device can also switch the manual / automatic function of the fire extinguishing device, so as to meet the needs of on-site emergency manual operation.

1. Installation of fire extinguishing device

① The fire extinguishing device is hoisted and installed, so that the gun can fully rotate 360 ° horizontally and -90 ° ~ 30 ° vertically, and can shoot directly below the fire extinguishing device, so that there is no blind spot in the protected area.

② The fire extinguishing device should be firmly fixed on the truss of the building to ensure that during spraying, it will not be shaken due to the back-force reaction and affect the accuracy of the fire extinguishing.

③ The integrated on-site control box is installed 1.5m from the ground, and a "manual controller" is installed in the box. Can be used to easily operate fire extinguishing equipment.

④ The installation position of the on-site control panel should be able to observe the corresponding fire monitor and approach the exit direction. Set the installation position according to the interior design and the actual situation on site.

6 )水炮到消防报警主机: SYV-75-5(视频线)。 ( 6 ) Water monitor to the fire alarm host: SYV-75-5 (video cable). (When the water cannon does not have video, no video or remote control cable is required, and the system does not have remote control function)

(7) Fire alarm host to pump room: RVV4x1.5 (start pump line, open pump feedback line).

:1、 由于水炮需 360度旋转,电缆线必须预留足够长度,否则会损坏设备! Note : 1. As the water cannon needs to rotate 360 degrees, the cable must be reserved with a sufficient length, otherwise the equipment will be damaged!
