- The Plena Voice Alarm System employs a simple and easy to use method of loudspeaker surveillance based on impedance measurement.
- On long wire runs, external influences, such as cable capacitance and speaker impedance, can negatively influence the reliability of the measurements.
- The dummy loads provide a filtered load exclusively at the pilot tone frequency.
- This greatly increases the dependability of impedance measurements, providing reliable break or short circuit detection, even on long wire runs.
