FHF Motor Driven Siren F3

The FHF Motor Driven Siren F3 delivers a powerful and unmistakable audible warning signal for alarm, warning, and critical signalling applications. Thanks to its characteristic mechanical siren tone, it produces a highly penetrating sound that helps ensure personnel can hear and recognise alarm conditions quickly, even in noisy industrial environments.

Furthermore, the F3 generates a high sound output of up to 123 dB(A) and provides 360° sound distribution, allowing operators to cover large areas with a clear and effective warning signal. As a result, the siren is well suited to critical applications where immediate attention and rapid response are essential.

The F3 features a robust aluminium die-cast housing finished with a weather-resistant coating for long-term durability. When fitted with the optional protection cover, the siren becomes suitable for outdoor installations, providing reliable performance in challenging environmental conditions.

In addition, the F3 is designed for short-time operation (S2 – 15 minutes) in accordance with VDE 0530 Part 1, making it ideal for alarm and emergency signalling duties.
