Loudspeaker with Emergency Stop Switch PP 9384 AT

The combination of the PP 7141 AT emergency stop switch and the PP 9381 AT loudspeaker offers more functionality than the sum of the individual devices. In addition to the possibility to set all device parameters using the application program and the system services, you can also:

- Output prewarnings with three different tone sequences
- Measure the temperature in the device
- Output selective prewarnings
- Realise point-to-point speech connections using the application program

and thus use the PP 2000 AT control units as an VF (voice frequency) station.
