24 Universal Cellular Communicator
The installer can choose which protocol to use: Contact ID or SIA.
The selected protocol is also applied to events generated by the panel and sent to the phone numbers with the IP Receiver
on GSM Path option enabled (see table on page 39).
To each event associated with the communicator's inputs, a specific
Customer code
can be assigned, while status events can be
assigned a unique user code.
The communicator handles a queue of 32 internal events. When the queue is full, further events are ignored.
The priority between internal and external events can be programmed by the installer (see “Priorities” on page 42).
For internal events, the times and manners in which they are sent are handled by the communicators: after a message is sent, the
unit waits for at most 1.25 seconds for the receiver to acknowledge reception (ACK). The unit will try to send a message up to
4 times. Events are transmitted to the digital receiver (see “Communicator” on page 46).
Tamper Restore Happens when tamper detection is enabled (see “Description of jumpers” on page 8) and
the communicator is closed again or mounted to the wall (versions with housing only).
FTC Fault Happens when an action fails (voice call, SMS, digital message).
FTC Restore Happens when the last action in the queue terminates successfully.
Periodic Call/SMS Happens when programmed (see “SMS/Voice Calls” on page 46).
