Mobile siren and speaker system MOBELA
Mobile siren and speaker system for vehicles for warning and announcements
The MOBELA 150-DII is an individually deployable mobile siren and speaker system and is particularly suitable for use in cars and vans. It consists of a compact, easy-to-operate control unit and a 360° omnidirectional speaker system. However, the MOBELA 150-DII is much more than just a mobile siren. Unlike conventional mobile siren systems, which can only play back siren signals and warning tones, MOBELA offers the option of playing back warnings and PA voice announcements using a microphone. The texts are stored on a USB stick, spoken directly into the microphone or transmitted via a radio microphone. The MOBELA 150-DII is therefore an effective, mobile warning device for all authorities and organizations with security tasks to warn and inform the public.
Product benefits:
- quickly ready for use without assembly effort
- Powerful sound propagation to all sides and upwards
- Command microphone for live PA announcements and text recording
- digital text memory for text recording and playback
- four different siren signals
- Simple and logical operating structure
- Control unit can also be operated with gloves
Application areas:
- mobile siren and speaker system as a supplement to warning the population with stationary sirens
- mobile siren and speaker system as a warning system for extensive industrial sites

Description of mobile siren MOBELA 150-DII
The Mobela 150-DII is a mobile siren that can be used individually and is particularly suitable for use in cars and vans. The mobile siren system consists of a compact, easy-to-operate control unit and a special omnidirectional omnidirectional loudspeaker system. Commissioning does not require any installation work and can be carried out by one person in a very short time.
The control unit includes a 300 watt Class-D amplifier and an i.MX7 processor with Linux operating system, 4 permanently stored siren signals (fire alarm, public warning, all-clear and evacuation) and 8 freely recordable memory locations, 8 additional memory locations via USB stick, an AUX connection for external devices and a command microphone for text recording and direct announcements. All functional and connection elements are located on the front panel and are marked with easy-to-understand symbols. An internal control loudspeaker makes it possible to listen to stored alarm texts or recordings played in via AUX independently of the operation of the external loudspeaker. Power is supplied via the cigarette lighter or a standard vehicle socket.
The spherical loudspeaker is equipped with a high-performance pressure chamber system. The sound is distributed effectively and evenly to all sides and upwards via a 360º horizontal / 270º vertical reflector. In addition, the spherical shape ensures an extremely low wind load when driving. The TÜV-approved magnetic plate ensures a secure hold on the vehicle roof (sheet steel) and allows quick, installation-free positioning. Feed-throughs for quick-release straps provide additional road safety, while four screw fastening points enable stationary fixed mounting. The ball loudspeaker is optionally available with an integrated double flashing beacon (DIN 14620 yellow/blue)
