1. Installation Precautions

Strictly follow the Code for Construction and Acceptance of Automatic Scanning and Positioning Water Monitor Systems.

Install the fire monitor only after piping is flushed and pressure-tested. Protect components from dust, moisture, and corrosion before installation.

Keep the protection area free of obstacles that block detection, positioning, or spraying.

Consider the weight of the device; ensure the pipe network has sufficient load capacity and stability during spraying. Reinforce supports if needed.

Handle gently during installation to avoid impact damage.

Keep the upper flange horizontal so the monitor hangs vertically downward.

Keep detection sensors clean; do not touch the lens with bare hands.

Avoid hitting control and detection components to prevent sensor breakage. Do not block the water outlet or sensor slots.

When wall-mounted, install the limit mark toward the wall; ensure 360° unobstructed rotation.

Adjust the large-space flame detector with the detection surface facing downward.

Clean the pipeline before installing the electric valve; install a filter upstream to prevent blockage.

After installation, protect the system against water, dust, and impact.

5. Network & Power Architecture

Ethernet Communication

Central control ↔ fiber receiver ↔ single‑mode fiber ↔ on‑site equipment

Power Supply

Central control cabinet → on‑site control box → water monitor

If no central cabinet, use nearby 220V supply

Important

Label all cables.

Separate power and communication cables to avoid interference.

---

6. Status Indicator Definitions

Intermittent flash (long off, short on): Normal running

Slow flash (long on, short off): Fault

High‑speed flicker: Positioning & spraying

Steady on: Scanning

---

7. Equipment Commissioning Steps

Step 1 Power On

Turn on central control → control box → water monitor.

Step 2 Check Monitor Reset

Monitor should rise to 65° after reset.

Indicator: intermittent flash = normal.

Abnormal? Check wiring, jamming, or twisted tail cables.

Step 3 Check CAN Communication

Control box should display the monitor's address.

If missing: check wiring, polarity, daisy‑chain structure.

If address conflict: double‑press Reset to factory restore.

Step 4 Add Camera & Channel

On central control, go to Channel Connection → search and add cameras.

Use manual adding mode.

Step 5 System Test

Verify remote control, video, and communication.

Perform ignition test: scanning, positioning, valve opening, water spraying.

Step 6 Parameter Setting

Set UV/IR sensor sensitivity, installation height, etc.

Adjust sensitivity if environmental interference exists.

Step 7 Spray Calibration

Ignite and test spray.

If the impact point deviates:

Enter calibration mode via the control box.

Adjust up/down/left/right to align impact point with fire point.

Exit calibration; parameters auto‑save.

Note

Calibration is only valid before left‑right swing.

If deviation is small: slightly increase "installation height" value.

Water Pressure Requirement

Pressure after the valve must meet design standards.

Use a pressure stabilizer to avoid large fluctuations.

8. Final Acceptance

After full commissioning, provide to the owner:

On‑site ignition test

Operation training

Daily maintenance instructions
