Kussmaul Safety Lock - Ignition Security - KM-091-148-12

The Kussmaul Safety Lock (Model KM-091-148-12) is a reliable, high-performance anti-theft and engine idle security system designed specifically for emergency vehicles, including ambulances, fire command vehicles, and police cruisers. This essential accessory allows operators to remove the ignition key while keeping the engine running, ensuring that critical onboard equipment such as radios, computers, and warning lights remain powered and operational at the scene without compromising vehicle security.

When the Safety Lock is engaged, the ignition circuit is bypassed. If an unauthorized attempt is made to move the vehicle—such as shifting into gear or releasing the parking brake—the system immediately interrupts the ignition, shutting the engine down to prevent theft. Normal vehicle operation is seamlessly restored once the original ignition key is reinserted and turned.
