Emergency situations demand flexible, immediate response capabilities that can adapt to dynamic incident scenarios and reach populations beyond fixed infrastructure coverage areas. The MOBELA 150-DII addresses these challenges as an individually deployable mobile siren and speaker system that has been specifically engineered for roof mounting on cars and vans. At its core, the system consists of a compact, intuitive control unit featuring a powerful 120W sine wave/180W peak power amplifier with Class-D technology and i.MX7 processor with Linux operating system, paired with a sophisticated 360° horizontal/270° vertical omnidirectional spherical speaker equipped with a high-performance pressure chamber system. This design ensures powerful, even sound distribution to all sides and upwards, maximizing coverage in any deployment scenario. MOBELA delivers four preset siren signals, live microphone announcements for real-time situational communication, and playback of pre-recorded messages, expandable via additional USB locations or AUX input for external devices. One person can deploy the system in minutes without any installation work, using the TÜV-approved magnetic mounting plate that ensures secure attachment to vehicle roofs while maintaining road safety through quick-release strap feedthroughs. The aerodynamic spherical design minimizes wind resistance during transit. The system draws power through standard vehicle sockets operating on 12V/24VDC. An optional portable power station provides independence from fixed power sources. The glove-operable control interface with clear symbolic markings and internal control speaker for independent monitoring ensures reliable operation. The MOBELA 150-DII serves as an essential supplement to stationary siren networks for population warning, provides comprehensive emergency communication for extensive industrial sites, and enables flexible incident command scenarios in remote areas.

This proposal aims to demonstrate how the MOBELA 150-DII mobile warning system addresses critical operational gaps in modern emergency management by providing rapid-deployment communication capabilities that adapt to dynamic incident scenarios. The primary objective is to showcase MOBELA’s unique value proposition as a comprehensive mobile alerting solution. We further aim to establish the MOBELA as an essential tool for first responders requiring immediate, flexible warning capabilities in areas beyond fixed infrastructure reach. This proposal directly leverages HÖRMANN Warnsysteme GmbH’s 70 years of specialized expertise in warning system development and manufacturing. The MOBELA represents our continued commitment to innovative, logical and beneficial solutions that reliably protect populations worldwide. By extending our comprehensive capabilities from stationary systems to advanced mobile platforms, we address the complete spectrum of emergency communication needs, from extensive industrial facilities, public areas to remote area response and mobile incident management. The proposal reinforces our core mission of reliably warning the public of imminent threats while demonstrating our team’s proven ability to deliver turnkey solutions. MOBELA exemplifies our innovative spirit in creating sustainable, resource-efficient products that empower authorities and security organizations with the most effective tools for population protection in an increasingly complex threat landscape.
The most significant innovation lies in its comprehensive communication ecosystem that integrates three distinct alerting modes within a single mobile platform. Unlike conventional mobile sirens restricted to predetermined warning tones, MOBELA combines standardized siren signals, real-time live announcements via command microphone, and sophisticated message playback from internal memory or USB devices. This tri-modal architecture enables incident commanders to adapt communication strategies instantaneously as situations evolve, delivering standardized alerts for immediate recognition, live instructions for dynamic guidance, and pre-recorded multilingual messages for diverse populations. This flexibility transforms mobile warning from simple acoustic alerting to nuanced, context-aware public communication for specific threats and hazards. The spherical omnidirectional speaker system with 360° horizontal and 270° vertical sound distribution represents breakthrough acoustic design. Traditional directional speakers create coverage gaps; MOBELA’s pressure chamber technology with integrated reflector system ensures uniform, powerful sound propagation in all directions and upwards simultaneously. This innovation maximizes warned population density per deployment while the aerodynamic spherical design minimizes wind resistance during transit, solving the dual challenge of acoustic performance and mobile operational efficiency. Another innovation factor lies in intuitive operation design. The control interface utilizes universally recognizable icons rather than text-based labeling, minimizes complexity through a limited number of function buttons, avoids nested menu structures requiring display navigation, and provides clear operational feedback through LED indicators. This human-centered design approach ensures rapid operational readiness and reliable functionality even under high-stress emergency conditions or when operators wear protective equipment.
The MOBELA operates on dual voltage capacity (12V/10A or 24V/5A passenger vehicles typically use 12VDC systems, trucks 24VDC), ensuring compatibility with diverse vehicle electrical systems. This flexible power supply capacity eliminates vehicle compatibility constraints. The control unit delivers comprehensive multi-modal capacity including microphone direct announcements, internal memory recording capacity and external playback via AUX input for smartphones and USB devices. Pre-programmed signal capacity includes standardized warnings: fire alarm, disaster alarm, all-clear object evacuation, chime signals and special alternating siren. The spherical loudspeaker operates reliably across temperature ranges from -20°C to +60°C, ensuring functional capacity in extreme cold and hot climates. IP55 protection classification provides dust and water jet resistance. The compact control unit and spherical loudspeaker provide portable deployment capacity manageable by single operators. The magnetic mounting plate delivers secure attachment capacity to smooth steel vehicle roofs with optional quick-release strap reinforcement for road safety compliance, while four screw fastening points provide permanent installation capacity when required. The loudspeaker’s 8-11 Ohm impedance ensures efficient power transfer and thermal management, maintaining consistent performance throughout sustained operation without overheating or acoustic degradation during extended emergency responses. Optional accessories extend operational capacity including dust containers for equipment protection during storage and transport, LED double flashlights for integrated visual-acoustic warning, loudspeaker stand plates for stationary deployment, vacuum suction cup attachments for non-magnetic surfaces, custom RAL color finishes, and 12V/17Ah power stations for vehicle-independent operation.
