Photo of Beka Model BA386 intrinsically safe flashing LED alarm beacon BA386 I.S. LED Flashing Beacon
  • Intrinsically safe
  • FM and ATEX certification
  • Choice of five colors
  • Two double flashes per second
  • IP56 environmental rating
  • Compatible with a wide range of barriers
  • Can power BR385 sounder with same safety barrier
Mark of certification to ATEX Directive Mark of Factory Mutual approval
The BA386 provides a bright flashing warning signal in a plant or processing area where ambient noise levels may drown out an audible alarm. It is significantly less expensive than traditional Xenon devices, yet has a similar light output and flashes more rapidly – making it more immediately noticable. Available in five colors to enable multi-stage alarm level protocols. Factory Mutual and ATEX intrinsic safety certification enable it to be used in virtually any classified hazardous location. Ask us about suitable intrinsic safety barriers.

Can be used in conjunction with a BR385 alarm sounder using a single 28V 93mA 0.66W Zener barrier or galvanic isolator. 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.

  • Intrinsically safe
  • ATEX II 1 G EEx ia IIC T6
  • Choice of five colors
  • Single, dual, or triple flash modes
  • Dual color option
  • IP65 environmental rating
  • May be combined with sounder and pushbutton
  • Isolated control connections
  • Compatible with a wide range of barriers
  • Pipe or wall mounting
Mark of certification to ATEX Directive
DA135 beacons offer multiple alarm modes to provide visual warnings in a variety of situations. A choice of five bright colors – including blue and white - plus single, dual and triple flash cycles. There's even a dual color option to warn operators of a relative change in status. Protective lenses appear clear until the LEDs are illuminated. Each beacon may be connected to a sounder and acknowledge/reset pushbutton to create a local alarm station. The electronics are totally encapsulated, and wiring connections are made in a separate terminal chamber. All control connections are fully isolated to simplify circuit design. Ask us about suitable intrinsic safety barriers and isolators.

Multi-color signalling comes to hazardous locations in the form of the LN870 light tower. Bright LEDS enable this design to be certified as intrinsically safe when used with the appropriate safety barriers — ask us about economical multi-channel isolating intrinsic safety barriers. Up to five lamp segments can be stacked and there are five different colors to choose from.
