Js-visg-m-s Manual May 2026

Based on the alphanumeric code JS-VISG-M-S, this device is a Photoelectric Beam Detector (Active Infrared Beam Sensor) commonly used in perimeter security systems. The code breaks down as follows:

• JS: Series (Jaiear Security / Javis)
• VISG: Product Line (Visible Beam)
• M: Mirror / Reflex (This is a Reflective model, meaning it uses a single unit and a reflector, rather than a separate transmitter and receiver).
• S: Standard Range (usually 5 to 15 meters outdoor/indoor).

Below is a comprehensive "proper text" manual for setting up, installing, and operating the device. js-visg-m-s manual

5. Advanced Configuration

13. Error Handling

dashboard.on("error", (err) => 
  console.error(`[$err.source] $err.message`);
  showToast(err);
);

Common errors:

• E001: Source timeout/unreachable
• E002: Join key mismatch between sources
• E003: Canvas size zero (hidden container)

5. Installation Workflow – Step by Step

The manual outlines a six-step procedure: Based on the alphanumeric code JS-VISG-M-S , this

1. Inspect – Check for shipping damage. Glass fragments inside the sleeve mean immediate rejection.
2. Clean – Use lint-free wipes and isopropyl alcohol (>99%) on connectors. Never touch the exposed fiber end face.
3. Launch – Connect the input to a low-power source (≤10 mW) initially. The manual states that CW powers >500 mW require a high-power variant (different model suffix).
4. Verify isolation – Measure back-reflected power with a return loss meter. Should be >55 dB.
5. Fixate – Do not clamp the isolator body directly; use a soft silicone pad or thermal adhesive.
6. Document – Record insertion loss and polarization axis orientation for each channel in a system log.

3.2 Wiring

1. Open the front cover of the detector using the provided tool or screwdriver.
2. Route the 4-core cable through the waterproof gland at the bottom or rear.
3. Connect wires to the terminal block:
   • (+): Power Positive (12-24V DC)
   • (-): Power Negative (GND)
   • COM: Common Relay Output
   • NC: Normally Closed Relay Output (Connect to your alarm panel zone)
   • TAMPER: Connect to the tamper zone of your alarm panel (optional).

const streamSource = new DataConnector.Stream("ws://...");
streamSource.onData((newRow) => 
  chart.appendData(newRow);      // add point
  chart.animate(300);            // transition
);

Auto-refresh:
