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).
