Mobile electronic siren for vehicles for warning and announcements

The MOBELA 150-D is an individually usable mobile electronic siren or mobile siren system and is particularly suitable for use in cars and vans. It consists of a compact, easy-to-use control unit and a 360 ° all-round spherical speaker system. But the MOBELA 150-D is much more than an electronic mobile siren. Compared to conventional mobile siren systems that can only reproduce siren signals and warning tones, MOBELA offers the option of using a microphone to play back warnings and voice announcements. The texts are simply saved on an SD card, spoken directly into the microphone or transmitted by radio microphone. The MOBELA 150-D thus represents an effective, mobile warning device for warning and notification the public for all civil defense and civil protection authorities and organizations.

Product benefits:

  • quickly ready-to-use without assembly effort
  • powerful sound distribution on all sides and upwards
  • microphone for direct announcements and text recording
  • digital text recording and playback
  • four different siren signals
  • easy to use - simple and logical to operate
  • control unit can also be operated with gloves
  • checked by the state fire brigade school in Würzburg, Germany
  • already in use hundreds of times

 

Applications:

  • mobile siren to supplement civil protection siren systems with stationary outdoor warning sirens
  • mobile system as warning system for industrial premises

Description mobile siren MOBELA 150-D

The siren model Mobela 150-D is an individually usable mobile siren and is particularly suitable for use in cars and vans. The mobile siren system consists of a compact, easy-to-use control unit and an all-round radiating special spherical speaker system. Commissioning does not require any assembly work and can be done by one person within a very short time.

The control unit contains a 150 W power amplifier, a digital signal memory with 4 different siren signals and 16 freely talkable text memory locations, an AUX connection for external devices (radio, cassette, CD, radio, etc.) as well as a command microphone for text recording and for direct announcements. All function and connection elements are located on the front panel and are identified by easy-to-understand symbols. An internal control loudspeaker enables listening to stored alarm texts or programs imported via AUX regardless of the operation of the external loudspeaker. The power supply is supplied via the cigarette lighter or a standard on-board socket.

 

The spherical speaker is equipped with a high-performance pressure chamber system that develops a sound pressure of up to 126 dB / 1 m. The sound distribution works effectively and evenly on all sides and upwards via a reflector 360º horizontally / 270º vertically. In addition, the spherical shape represents an extremely low wind load when driving. The TÜV-tested magnetic plate ensures a secure hold on the vehicle roof (sheet steel) and allows a quick and assembly-free positioning. Feed-throughs for quick-release belts provide additional traffic safety, four screw fastening points enable stationary fixed installation. The spherical speaker is optionally available with an integrated double flash beacon (DIN 14620 yellow / blue).
