  • Choice of variants to suit range requirements of the station: FS1/1MEx – 0.5 or 1 mile range depending upon output level selected. FS3/2MEx – 2 mile range stacked unit using three of the same drivers.
  • Durable lightweight aluminium casting, with anti-corrosive treatment and stainless steel diaphragms give excellent protection against the elements.
  • Reliable driver with MTBF of over 10 years with no maintenance. Easy access for driver replacement.
  • Simple mounting arrangement for bolting to any flat surface. Optional provision for Lantern mounting bracket on the top, saving space.
  • Efficient sound transmission. Square wave oscillation helps to reduce reflective interference thus increasing performance.
  • Integrated Control Circuit, with no separate controls required. Able to be programmed to sound morse ‘U’ or other IALA characters.
  • Easily able to be controlled externally by an FD7100 Fog Detector or PELANET monitoring system.
  • Baffles available for reducing sound emission by about 10dB over a 90o Angle, to reduce annoyance where people are located.
