New Cosmos NV-120Mx Single-Point Gas Alarm Controller
The NV-120Mx is a single-point gas detection alarm unit designed to receive signals from compatible DC 4–20 mA gas detectors.
Plan the Right Configuration
The NV-120Mx is a single-point gas detection alarm unit designed to receive signals from compatible DC 4–20 mA gas detectors. It provides visual and audible alarms, configurable outputs and optional backup power. Gas selection and measurement range depend on the connected detector.
Gas and measurement range are determined by the connected detector. A shared 4–20 mA signal type alone does not establish compatibility with every detector.
