TOMAR Electronics flameproof BExCS110-05-R combination alarm horn sounder and Xenon strobe beacon with omni-directional horn is suitable for Zone 1, 2, 21 & 22. Approved to IECEx, ATEX, Ex EAC and INMETRO standards.

The radial horn on the compact BExCS110-05-R distributes the audible warning signal omni-directionally allowing the visual signal to be orientated optimally. The alarm horn & Xenon beacon may be connected from a single power supply for simultaneous operation or from separate supplies for independent operation.
The BEx range features enclosures manufactured from corrosion proof, marine grade copper free LM6 aluminum with a chromate and powder coat finish. All models have two M20 cable entries, large termination areas containing in & out terminals and an ingress protection of IP66/67.

  • Omni-directional sound output.
  • Marine grade, corrosion proof, LM6 aluminum enclosure
  • Automatic synchronization on multi-beacon & sounder systems.
  • Beacons can be set to ‘flip-flop’ alternating mode with other units on multi-beacon systems.
  • Xenon tubes mechanically secured against shock & vibration
  • Very large termination area.
  • Dual M20 cable entries – adapters available.
  • Stopping plug included.
  • Ratchet adjustable stainless steel ‘U’ bracket.
  • Reverse polarity diode fitted.
  • IP66/67 ingress protection.
  • 120 candela effective light intensity.
  • UV stable PC, field replaceable, color lens filters.
