forede ZDMS Series Automatic Fire Monitor is an organic combination of infrared/ultraviolet sensing technology, signal processing technology, communication control technology, computer technology and mechanical transmission technology, which can automatically monitor fires within the protection range of special places all-weather. Once a fire occurs, the device is immediately activated, and the fire source is scanned and positioned horizontally and vertically. After determining the two positions of the fire source, the central controller sends out a fire alarm signal, starts the water pump, opens the valve, and the fire extinguishing device is aligned The fire source will shoot water to extinguish the fire. After the fire source is extinguished, the central controller will issue an instruction to stop the water injection. If there is a new fire source, the fire extinguishing device will repeat the above process and return to the monitoring state after all fire sources are extinguished.

Installation Instructions
1. Laser Positioning in Daylight
Q: The "laser positioning indication"-is it visible in bright daylight, and how to ensure it works in high - glare environments?
A: Laser visibility in daylight depends on intensity-high - power lasers remain visible but may require adjustments (e.g., aiming at darker surfaces). In high - glare areas, use the high - definition screen monitoring to supplement laser targeting, cross - verifying the jet direction.
2. Nozzle Pattern Selection Logic
Q: How does the monitor decide between "Straight stream & Fog or Straight Stream" nozzle patterns automatically?
A: The system uses fire - size algorithms: small fires may trigger fog (for cooling/protection), large fires activate straight stream (for penetration). Operators can also manually override via the control box, prioritizing patterns based on situational needs.
3. Waterproof Enclosure Limits
Q: The electric driver and control unit are waterproof-what's the depth/duration of water exposure they can handle (e.g., in heavy rain or floods)?
A: Waterproof ratings (e.g., IP66/IP67) protect against water jets and temporary submersion (up to 1m for 30 mins). In flood - prone areas, install the monitor above flood levels or use elevated mounts. Consult the manufacturer for exact immersion specs.
4. 220V AC Power Compatibility
Q: With optional 220V AC power-can the monitor operate on 110V AC with a step - up transformer, and will it affect performance?
A: Yes, but use a transformer rated for the monitor's power (monitoring 1W + detecting 50W). Ensure the transformer provides stable 220V output; voltage fluctuations may disrupt automatic tracking or jet - control functions.
5. Automatic Tracking Accuracy
Q: Using "Infrared ray & UV sensor technology"-how accurate is the automatic tracking in complex environments (e.g., multiple heat sources)?
A: Dual sensors reduce false positives: infrared tracks heat, UV confirms flame presence. In complex environments, the system prioritizes the largest/most intense fire. For multiple fires, operators may need to switch to manual mode to address smaller blazes.
6. Mounting Height and Blind Spots
Q: Mounting height is 8-15 m-how to avoid blind spots (e.g., behind tall equipment) in large industrial spaces?
A: Use multiple monitors in a grid pattern to cover blind spots. Position monitors to overlap monitoring radii (80 m) and adjust angles during setup to ensure line - of - sight coverage. Conduct a site survey to map potential blind spots and optimize placement.
7. RS485 Data Security
Q: Using RS485 communication-how to secure data transmissions (e.g., preventing unauthorized control of the monitor)?
A: Implement RS485 bus isolation, use encrypted protocols (e.g., MODBUS with authentication), and restrict physical access to the control network. Regularly update firmware to patch vulnerabilities, ensuring only authorized systems can send commands.
8. Power Consumption and Battery Backup
Q: "Monitoring 1W, Detecting 50W"-can the monitor run on battery backup during outages, and what's the runtime?
A: Yes, with a 220V AC - compatible UPS or battery inverter. Runtime depends on battery capacity: a 100Ah battery (220V) can power monitoring for ~100 hours or detection for ~4 hours. Size the backup based on outage risks.
9. Targeting Time in Smoke
Q: "Targeting Time ≤60 S"-does this hold in smoke - filled environments, and how do sensors perform through smoke?
A: Smoke scatters infrared/UV signals, potentially increasing targeting time. The system uses adaptive algorithms to filter noise; in heavy smoke, targeting may take longer (but still ≤60 S if sensors can "see" flames). Pre - position monitors near likely fire sources to reduce response time.
10. Alloy Construction and Vibration Resistance
Q: The "hard anodized aluminum alloy construction"-how does it handle vibrations (e.g., in industrial facilities with heavy machinery)?
A: Anodized aluminum offers good vibration resistance, but continuous high - amplitude vibrations may loosen fasteners. Use anti - vibration mounts during installation and tighten connections regularly. Inspect for structural wear during maintenance.
