MARTIN-Horn® 2097 GM

Safety in action for emergency doctor, ambulance and police


The company Deutsche Signal-Instrumenten-Fabrik Max B. Martin had already developed in 1932 together with the fire and police services a siren which was legally prescribed as a special signal for prioritised road users (legislator: “Warning device with a series of tones of different
frequencies”). Every special signal device on German police and fire service vehicles before 2nd World War was actually a MARTIN-HORN®.

The registered tradename MARTIN-HORN® refers to sirens which use one or more tones to form a warning signal. The genuine MARTIN-HORN® is recognised by its penetrating, trumpetlike tones.

Unlike the MARTIN-HORN® device 2298 GM, the 2097 GM device does not require tremolo tuning.
