The ZÖLLNER Diamond Triple MAKROFON YM125 is a diaphragm sound transmitter of three Makrofons operating on compressed air. The signal is released by electrovalves or manually using a hand pull-rope. To avoid the costly laying of a pull-rope, a second electromagnet for emergency voltage can be provided. A thermostat controlled anticondensation heating keeps the sound horn and the operating valve free from condensed water and thus from ice.

MAKROFON YM75F/260 and MAKROFON YM75F/370

The ZÖLLNER ZET-Horn was the first piston type whistle on the world market driven by an AC 3phase motor. An essential component is the piston inside the cylinder driven by an AC 3phase motor via connecting rod, crankshaft and gearwheels. The piston oscillates at a certain frequency which makes the air inside the sound horn vibrate in resonance to produce a sound audible over a wide range.
