Merlin DRS Detector
Standalone or Controlled Via A Merlin Controller
Introducing the Merlin DRS Duct Mount Sensors from S&S Middle East, specifically engineered for reliable gas detection within HVAC systems in commercial and light industrial environments. These sensors are optimized for monitoring air quality and gas concentrations in ducted systems, ensuring effective detection of a variety of gases, including natural gas, carbon monoxide (CO), carbon dioxide (CO2), LPG, hydrogen (H2), nitrogen dioxide (NO2), and refrigerants.
The Merlin DRS sensors incorporate advanced detection technologies tailored for duct mount applications, providing swift identification of gas leaks to enhance safety within operational spaces.
Featuring a traffic light indicator display, these sensors deliver clear visual signals regarding gas levels, while in-built audible alarms promptly alert personnel to any potential hazards, facilitating immediate action.
Designed for seamless integration into existing HVAC systems, the Merlin DRS sensors offer power options of 24V AC/DC. They easily connect to buliding management systems (BMS) via Bacnet MS/TP or Modbus RTU, ensuring efficient monitoring and control.
The plug-and-play installation simplifies deployment, making them ideal for critical environments where gas safety is paramount.
