    Addressable Gas Detector

    Artikelnummer: HY-AA340R

    Catches a natural gas or LPG leak early
    The addressable gas detector is set in the field for natural gas (methane) or LPG (propane) and alarms at a threshold of 8% ± 3% LEL. Its integrated dry contact relay switches between NO and NC and drives external devices directly.

    Key features
    Selectable gas typeIt works in natural gas (methane) or LPG (propane) detection mode.
    Dry contact relayThe integrated relay is set as NO or NC and triggers external devices.
    Detection rangeIt measures from 0% to 100% LEL and alarms at 8% ± 3% LEL.
    Mounting positionMethane detection mounts on the ceiling at 30 cm or less from it, propane detection on the wall at 30 cm or less from the ground.
    Low drawStatic current stays at 30 mA or below and alarm current runs at 35 mA.
    Durable buildNon-loosening screws on the base terminal ease installation, and the contact material resists acid and rust.
