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. Hear sample alarm tones.
Photo of combined Beka BA386 intrinsically safe alarm beacon and BR385 intrinsically safe alarm sounder for use in hazardous classified locations
Can be used in conjunction with a BA386 alarm beacon using a single galvanically isolated barrier. The BA386 beacon includes terminals to power the sounder, and for an external push button to silence the sounder. The silence time is adjustable from 1 to 30 minutes. We can even supply a kit to combine the two units.

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 (EOL) resistor or diode may be installed inside the beacon enclosure for line monitoring purposes. An alternative stainless steel pipe mounting kit is available.
