220 Series 27
Priority handling
The communicator can:
forward panel voice messages via GSM;
forward panel Contact ID messages on the GSM voice channel;
send its own voice messages;
send its own SMS;
send its own digital messages (Contact ID/SIA) on the cellular data network;
handle incoming SMS;
send data packets for supervising communications with IP receivers.
The priorities of all the above actions can be set on the Console (see “Priorities” on page 42).
The following table shows the factory default priorities.
Factory operation
If the device is transmitting an event and another event of higher priority occurs, the communicator interrupts transmission of
the lower priority event and queues it.
After the higher priority event has been transmitted, the communicator tries again to transmit the interrupted (queued) event.
If several events of the same priority occur together, they are queued and transmitted in sequence.
The communicator's voice messages have lower priority than panel events: if a panel event occurs while the communicator is
transmitting a voice message, the communicator hangs up and the panel takes over the line (pick up detected); after the
event has been transmitted (hang up detected) the communicator tries again to transmit the interrupted (queued) message.
If the communicator's voice messages have higher priority and a panel event occurs while a communicator voice message is
being sent, the communicator must provide the engaged signal to the panel and continue transmitting its messages.
Communicator SMS have lower priority than panel messages and the communicator's voice messages, but an SMS cannot
be interrupted while it is being sent.
The lowest priority is given to data packet transmission for supervision of communications with the IP receivers.
