AQ 37 R - Acoustic acknowledgement

#SCHAEFER#elevator acoustic signalling#aq 37 r - acoustic acknowledgement#elevator control element

The AQ can be operated in 3-wire as well as 4-wire technology in such a way that it only triggers when the call has been accepted by the control unit. The AQ is also triggered when an already acknowledged command transmitter is actuated (see EN 81-70 (D) table 4). The volume can be adjusted via potentiometer.

Using the AQ reduces the voltage with which the control is called. With an input current of 10 mA with the AQ 37 by 1.7 V. If this causes problems, use the AQ 37 FST. Here, the call voltage is reduced by typ. 1.4 V at an input current of 10 mA.
