Sound detector for emergency vehicles that allows the entry of firefighters, ambulances, police... without having to stop.
The sound detector is capable of identifying the signal emitted by the approved sirens supplied to public administration/rescue vehicles (Police, firefighters, ambulances, etc...).
In emergency situations, the sound detector will identify the signal from the siren and proceed to lower the stem of the automatic bollard to ground level or raise the pole of the automatic barrier, to allow vehicles to pass.
Vehicle sound detectors ideal for installing next to our automatic bollards and/or automatic barriers.
