While the siren is active, press the Wail function button (upper left corner) once. Each press cycles through different siren sounds. The selected sound is stored in memory and will be used the next time the siren is activated. For more details, refer to the installation and operation manual in the function activation section.
The intercom includes seven siren sounds:
Characteristics:
Chirp – Mass deterrence
Phaser – Commonly used by ambulances and fire trucks
Horn – Typically used at avenue crossings
Wail – Often used when the vehicle is stationary
Hi-Lo – Frequently used by police vehicles
Feedback noise occurs when speaker output is picked up by the microphones. This may happen if the vehicle lacks proper shielding for the PW’s power level, if acoustic insulation needs reinforcement, or if windows or doors are open.
To prevent this, calibrate the intercom volume with windows closed, doors shut, and in an open space. For further details, refer to the installation and operation manual under internal speaker volume setting, internal volume, external automatic volume adjustment (VAA), and external speaker volume setting, external volume.
