Introducing the Hootronic range of digital alternative to electro-mechanical sounders

HA105N Electronic Siren, Buzzer, Claxon & Bell,

The products in the Hootronic range have 5 user selectable ‘traditional’ sounds including:

  • Tone 1 : Industrial Claxon
  • Tone 2 : High Frequency Mechanical Siren
  • Tone 3 : Medium Frequency Mechanical Siren
  • Tone 4 : Electro Mechanical Buzzer
  • Tone 5 : Mechanical Bell

Each of these sounds have two additional, remotely selectable, alarm stages.
Remote switch generates genuine ‘tail off’ to sound when alarm is terminated.

  • Automatic synchronisation on multi-sounder system.
  • Continuously rated.
  • Stainless steel fixings.
  • Unit can be mounted using external lugs or internal BESA compatible fixing positions.
  • Duplicate cable terminations (in & out for daisy-chain installations).
  • Tropicalisation available on request.


  • GOST-R certificate: POCC GB.JB05.H00144

HA105N Electronic Siren, Buzzer, Claxon & Bell,

Applications and users that have traditionally demanded conventional electromechanical calxons, sirens, buzzers and bells can now choose the next generation alternative.

The technology employed in the Hootronic range features the latest in amplifier and digital to analogue conversion technology. The E2S Hootronic series of products faithfully reproduce the sounds made by legacy electro-mechanical signalling devices but in a modern, reliable and cost effective way. With output levels of up to 112dB(A) at 1 metre the HA105N surpasses legacy electro-mechanical devices in performance and effectiveness, it is also continuously rated, requires zero maintenance and the signal quality will not degrade with age.
