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.
