Sirens / Speakers - Certification - ECE R10 covers the approval of vehicles and electrical/electronic equipment with regard to electromagnetic compatibility (EMC). It sets requirements so in-vehicle devices limit electromagnetic emissions and have adequate immunity to interference.

Choose a warning sound system by intended use, operating voltage, power and control method. The range includes hobby and professional sirens, separate horn speakers and accessories for wiring and installation. Before ordering, check that the speaker power and impedance match the control unit, confirm the vehicle voltage and select any required functions such as a microphone or preset tones.
