    Addressable Smoke Detector

    Stock Code: HY-2301-RE

    Watches smoke density and reports fire early
    The addressable smoke detector mounts on the ceiling and triggers an alarm on smoke passing through its optical maze. A background compensation algorithm sets the alarm threshold according to the contamination level of the maze on its own.

    Key features
    Adaptive thresholdIt sets the alarm threshold from the maze contamination level automatically and extends the cleaning cycle.
    CoverageIt covers 150 m² at installation heights below 4 m and 80 m² between 4 m and 12 m.
    Relay outputThe relay output drives external devices, and the indicator light signals the alarm.
    Low currentStatic current stays at 300 µA or below and alarm current at 6.5 mA or below.
    Easy installationNon-loosening screws on the base terminal speed up mounting, and the contact material resists acid and rust.
    Standard complianceIt is designed in accordance with the EN 54-7 standard.
