47.3.3 Press-to-talk (PTT)

Using the PTT (Press-to-talk) action, a call with a predefined priority based on a call macro can be started in one or more predefined zones or zone groups. When the activator of a PTT action is released, the call is stopped after completion of the running phase of the call. See figure 47.10 for an overview of the Action programming page for a PTT key. Configuring a PTT action is similar to configuring a Call activation key action (see section 47.3.4).

The PTT keys of call stations and call station keypads are linked to the status LEDs (see section 15.3 and 18.2.4). Only one PTT key can be active at the same time.

47.3.4 Call activation key

Using the Call activation key action, a call with a predefined priority based on a call macro can be started in one or more predefined zones or zone groups. It is also possible to activate a predefined control output. When the activator of a Call activation key action is released, the call is aborted. See figure 47.11 for an overview of the Action programming page for a Call activation key.

If more than one action (up to a maximum of 5) is configured for a Call activation key, see section 43.2.5, then also multiple sets of Call macro, Priority and Zones can be configured here.

Note

This action can also be assigned to control inputs.

Note

If the system contains call stackers, use the action type Toggle with abort on repress or Momentary with abort on repress, since calls are automatically deleted from the call stackers when they are aborted immediately.

•Call macro - Assigns a call macro to the key or control input.

•Priority - Sets the priority of the call. The ranges of priorities offered depends on the type of call station (normal: 32 to 223, emergency: 32 to 255). When the priority of the Call activation key action must be the same as the priority of the call macro, set Priority to <Default>.

•Available outputs - Shows the available zones, zone groups and control outputs. Use the dropdown list to choose the type of outputs that are shown.

•Add/Remove buttons - Using the > and < buttons, selected outputs can be added to or removed from Assigned outputs.

•Assigned outputs - Shows the outputs that have been assigned to the key or control input.
