Seven points for automatic tracking and positioning of fire-fighting water monitors: electronically controlled fire monitors

1. The power supply of the automatic tracking and positioning fire water monitor should be 220V, 50Hz single-phase power supply, and should be equipped with a stabilized power supply device.

2. In places with high environmental interference, when ordinary video coaxial cables cannot meet the requirements, balanced transmission or optical fiber transmission should be considered.

3. The image type fire detector should be supplied with a dedicated line through the isolation transformer; the remote detector can supply power nearby, but the equipment should be equipped with protective devices such as power switch, fuse and voltage regulator.

4. Automatic tracking and positioning of fire water monitor grounding is an important measure to suppress interference. When it is found that the automatic tracking and positioning of the fire water monitor produces unknown faults and false alarms, the first consideration is whether the automatic tracking and positioning of the fire water monitor is well grounded. The grounding is anti-corrosion. For interference grounding, the grounding resistance should be less than 4 ohms.

5. It is not allowed to connect the grounding of the automatic tracking and positioning fire water monitor with the protective ground or the neutral wire of the power supply, otherwise, it may cause damage to the equipment.

6. During construction, the grounding point of the automatic tracking and positioning fire water monitor controller should be linked to the same point, and this connection point should be connected to the shielding ground wire connection end. In addition, the automatic tracking and positioning of the bus in the fire water monitor , Telecommunication lines, broadcast intercom lines, etc. shall not be connected to any form of ground or neutral wire to prevent inactivity of the equipment.

7. According to the actual situation and characteristics of the site, the installer of the fire monitor will be confessed. The installer will check the drawings to locate the equipment, clarify the line direction, the elevation requirements and the installation method of the line at different parts, the combination method of the wall and the top piping, Equipment wiring installation elevation size and fixing method, etc.
