Merlin Gas Detector i-S:

The Merlin Gas Detector i-S is an advanced gas monitoring system designed to enhance safety in a wide range of environments, including boiler rooms, hospitals, laboratories, high-rise buildings, and other commercial or industrial spaces. With a highly accurate sensor and a clear digital TFT display, this detector ensures real-time gas level monitoring and provides early warning alerts to prevent potential hazards.

Designed for effortless installation, it is compatible with the Merlin GDP2 Gas Leak Alarm or can be used as a standalone sensor.

Compatible gases:

• Refrigerant gases (R32/134a/410a)
• Natural Gas (NG)
• Carbon Monoxide (CO)
• Low Petroleum Gas (LPG)
• Hydrogen Gas (H2)
• Carbon Dioxide (CO2)

Key Benefits of the Merlin Gas Detector i-S:

The 1.8” TFT screen displays real-time gas concentration levels, while the traffic light indicator system ensures quick visual assessment:
🟢 Green – Normal operation
🟡 Yellow – Pre-Alarm (LOW Alarm)
🔴 Red – Alarm Triggered (HIGH Alarm)

✅ Audible & Visual Alerts
In the event of a gas leak, the Merlin Gas Detector i-S provides multiple alert mechanisms to ensure rapid response:

• Loud Audible Alarm – >65dB @ 1m, ensuring awareness even in noisy environments.
• Visual Alarm Indicators – Screen displays a red dot when the alarm relay has latched, alerting users to take immediate action.

✅ Flexible Installation & Compatibility

• Standalone Operation – The Merlin Gas Detector i-S functions as a fully independent gas sensor, making it suitable for various applications.
• Seamless Integration – Compatible with the Merlin GDP2 Gas Leak Alarm, allowing for enhanced safety system integration.
• Multiple Mounting Options – Can be installed at different heights based on gas type:
  • Lighter gases (e.g., Methane, Hydrogen, CO) – Mount near the ceiling.
  • Heavier gases (e.g., Propane, CO₂, LPG) – Install close to the floor.

✅ Reliable & Long-Lasting Performance

• NDIR (Non-Dispersive Infrared) Sensor Technology for high-precision detection.
• Expected sensor lifespan varies based on usage and gas exposure but includes an End-of-Life Notification, ensuring timely replacement.

✅ Enhanced Safety Coverage

• Recommended coverage: ~50m² per detector (multiple units may be required for larger areas).
• Designed for use in hazardous areas where gas leaks pose a significant risk.

Recommended Detector Placement:

Installation heights may vary depending on airflow, temperature conditions, and specific application requirements.
