Alarm Call; Semi-Duplex Conference (Talkback Call) - Alphatron AlphaConnect Classic Operation Manual

2.11 Alarm call

When PA speakers are used with the AlphaConnect system, alarm distribution calls can be made. Alarm calls can be
received by the communication stations with speakers only (AlphaConnect P211, AlphaConnect P421 and AlphaConnect
P411 communication stations).
The AlphaConnect system has the capability of distributing 7 different alarm tones.
The default system call number of an alarm call is #09.
When an extension has initiated an alarm call, the alarm tone will be heard in the handset as an acknowledgement of the
fact that the alarm generator is really operating.
During an alarm distribution, the REDIAL button can be used to toggle the call between an alarm call and a paging call.
Dial the alarm system call number of the desired alarm type. When the alarm is sounding, press the REDIAL button.
This will stop the alarm generator and switch on the microphone of the handset of the telephone used to initiate the call.
Speak loudly and directly into the microphone to send your voice message. Use the REDIAL button to return the call into
an alarm tone distribution call.
Alarm calls can be made from any extension or station given the privilege to do so.
Hook on the telephone to terminate the alarm call.
Refer to the AlphaConnect Installation Manual for setup of alarm calls.

2.12 Semi-duplex conference (TalkBack call)

A TalkBack call is primarily used from a bridge telephone (master station/controller) and several communication stations
(slave stations/command group units) to form a command group.

Example: As shown in Figure 16: Semi-duplex conference on page 31, the bridge telephone is the master. The
primary line is between the bridge telephone and communication station 1. The secondary lines are for the listeners only
(communication station 2 and 3).
