    4-channel network loudspeaker line monitoring module designed for continuous diagnostics and safety of 100V public address (PA) and voice evacuation systems. The device analyzes line impedance in real time, compares it with a calibrated reference value, and instantly detects any deviations that may indicate a system fault.

    This solution is especially important in facilities where audio system reliability is critical: schools, hospitals, shopping centers, offices, factories, hotels, or apartment buildings. The device allows early detection of problems and helps prevent situations where an audio message or evacuation signal does not reach the required zone.

    Functions

    Continuous monitoring of line impedance with precise percentage deviation evaluation
    5-state diagnostics providing a complete overview of line condition
    Automatic audible warning when a fault is detected
    LED indicators for fast problem identification
    Calibration function ensuring accurate system adaptation to real load conditions
    Safe operation with amplifiers – detection is disabled when the line is active

    Applications

    For home users: Enables monitoring of building loudspeaker line status without specialized measuring equipment, ensuring reliable operation of announcement and emergency systems; clear indication allows quick response to faults

    For electricians/installers: An excellent tool during installation, testing, and commissioning; helps quickly detect cable breaks, incorrect loads, and short circuits, reducing error risk and saving time on site

    For engineers / system designers: An ideal solution for PA / Voice Alarm system maintenance, ensuring compliance with safety and regulatory standards; especially useful in large facilities with multiple loudspeaker zones

    Advantages

    Accurate impedance measurement (20 Ω – 2 kΩ)
    5 clearly defined status states
    LED + audible alarm
    Calibration function
    Compatible with 100V systems
    Low power consumption (<10W)
    Professional solution for critical audio systems

    Limitations

    Line diagnostics are not performed while the system is actively transmitting audio
    Designed exclusively for 100V loudspeaker lines (not a universal cable tester)
