Tone sequence system 614/624
The tone sequence system is designed as acoustic support to the light signals for emergency vehicles as defined in the road traffic licensing regulations. Piercing and clear special signals, as well as the option to use public address and electronic compressor signals, provide an extra dimension to the visual warning systems.
