MSS Detector Base Sounders

MSS Detector Base Sounders

  • Volume up to 100 dB(A)
  • Electronic tone generator integrated into the signaling device
  • 11 different tone variants can be selected (incl. DIN tone)
  • Great reliability and long service life
  • For surface and flush-mounted cable feed
  • The LSN types maintain LSN loop functions in the event of wire interruption or short-circuit thanks to two integrated isolators

Detector Base Sounders are used when the acoustic signaling of an alarm is required directly at the site of the fire.
