Loudspeaker with Emergency Stop Pullkey PP 9391 AT

The combination of the PP 7145 emergency stop cable 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.
