Vehicle PA and organisational siren systems

Organisational sirens combine an amplifier, microphone and sound modes for announcements and signalling when managing traffic in private sites, at events or during other organisational activities. The range includes 80W, 100W, 200W and 400W systems for 12V, with a selected 400W model also available for 24V. Depending on the version, features include three to 28 preset sounds, bullhorn function, a wireless microphone controller, switching for two lighting circuits or USB audio playback. Compare the vehicle voltage, amplifier output, speaker compatibility and quantity, control method and required inputs or outputs. Installation needs correctly fused power, wiring sized for the current draw and safe positioning of both speakers and controller. These systems are not automatically approved as special audible warning devices for public-road use. Use only sounds and functions permitted at the installation location, and do not test the siren in an enclosed space or near people without hearing protection.
