BR385 I.S. Alarm Sounder
  • Intrinsically safe
  • Up to 103 dB(A) output
  • 49 first stage, 21 second stage,
    and 9 third stage alarm tones
  • PFEER compliant
  • Volume control
  • IP66 environmental rating
  • Input overload protection
With forty-nine alarm tones to choose from these intrinsically safe sounders allow you to pick sounds which will penetrate the ambient background noise in your plant. Second and third stage tones are easily triggered by secondary control circuits. Tones are selected by DIP switches, and there's also a volume control. A crystal controlled oscillator accurately defines the frequency and repetition rate of each alarm signal. This insures that multiple sounders set to the same tone(s) remain synchronized throughout your plant. Ask us about suitable intrinsic safety barriers.
BExS110D Alarm Sounder
  • Flameproof.
  • ATEX EEX d IIC T4 certification.
  • Up to 113 dB(A) output.
  • 32 different tones.
  • Second & third stage outputs.
  • PFEER compliant.
  • IP67 environmental rating.
  • 12, 24, or 48VDC; 115 or 230VAC .
  • Mounting bracket included.
Where an EEx d installation is acceptable the BExS110D sounder will provide an extremely effective audible alarm. There's a choice of thirty two user selectable tones, plus provision to enable second and third stage sounds by secondary control circuits. In the case of 24VDC powered units an end-of-line resistor or diode may be installed inside the beacon enclosure for line monitoring purposes. An alternative stainless steel pipe mounting kit is available.
