The AR 37 (AQ-Ruf) is specially designed for landing operating panels (call up + down). It emits a tone when a command transmitter is pressed. When an already acknowledged command transmitter is pressed, the AQ-Ruf also triggers. The AR 37 (AQ-Ruf) is suitable for common anode/common cathode as well as for 3-wire technology and 4-wire technology.

Attention: 4-wire pushbuttons (e.g. MT 42 IX) must also be used for 3-wire controls!

Use AQ 37 or AQ 37 FST if the acoustic acknowledgement may/should only take place when the call is accepted by the control unit.
