The selected item is an industrial General Monitors Infrared Point Gas Detector IR2200 (partially matching the legacy IR2100 series design), which is a microprocessor-based system used to continuously monitor combustible hydrocarbon gases like methane.

IR2200 is often a specialized configuration (or differs by approval rating and target gas range), though in the General Monitors catalog, the IR2100 serves as the primary legacy/older-generation point IR detector. [1]

Key Specifications & Features

• Detection Principle: It utilizes dual-beam infrared technology to measure gas concentrations within the Lower Explosive Limit (LEL).

• Power Requirement: Rated for standard 24 VDC nominal operation with low power consumption.

• Fail-to-Safe Design: Operates on a continuous self-check cycle to detect component or optic blockages without causing false alarms.

• Output Signal: Typically outputs an industry-standard 4-20 mA analog signal proportional to the concentration of the gas, alongside digital Modbus communication.

• Hazardous Certification: Features an explosion-proof metal housing certified for Class I, Division 1/Zone 1 environments where flammable gases may be present.
