AQ - Acoustic Acknowledgement
The AQ creates two short beeps once a button is pushed. With 3-wire technology the AQ will only sound if the call was accepted by the controller. When pushing an already confirmed button the AQ will also sound (see EN 81-70 (D), chart 4). The volume is adjustable via a potentiometer.
