The Merlin Gas Detector X-Range for Natural Gas is designed to work seamlessly with the S&S Merlin range of Gas Detection Panels and Safety Systems. Featuring a semiconductor-type sensor, this detector is ideal for industrial and commercial indoor applications, offering a compact, modern, and digital design that is both aesthetically pleasing and easy to install.
Precise Detection: Designed to be installed approximately 300mm from the ceiling to effectively detect Natural Gas buildup, which is lighter than air.
High-Level Installation: Should be placed at a high level to ensure optimal detection of natural gas, triggering at 10% of the lower explosion level.
Alarm Activation: When gas levels reach the threshold, the detector activates the attached Merlin system, causing an alarm state and instant isolation of the gas valve.
Reset Functionality: Requires finding the source of the gas buildup, clearing the detector head, and resetting the attached Merlin panel to resume normal operations.
Dual-Level Alarms: Features both low and high-level alarms for comprehensive safety monitoring.
Visual Indicators: Traffic light-style gas level display indicator provides clear visual feedback on gas levels.
Modbus RTU Compatibility: Ensures easy integration with existing systems.
Built-In Test Button: Facilitates onsite commissioning and ensures proper functionality.
Easy Installation: Straightforward to install, making it suitable for various applications.
System Compatibility: Can be used with other Merlin Gas Safety Systems for enhanced safety management.
Reliable Warranty: Backed by a 3-year warranty from S&S Northern Ltd for peace of mind.
