Communicator

Connecting the Communicator

The control unit has an internal communicator on its main PCB. This is an

auto-dialling modem.

If necessary, a standalone communication device can be connected through a

wiring harness to interface pins on the main PCB (this is known as a plug-by

communicator).

The communicator can be used for:

• Transmitting alarm signals to alarm receiving equipment at a central

monitoring station using Scancom Fast Format, Scancom SIA (Security

Industry Association) or Contact ID (set with Command 103).

• Connecting to a PC based at a remote engineering centre. Using

Scantronic Downloader software, the remote PC can upload and download

system parameters (including the event log and diagnostics), set and unset

the alarm system, and carry out other special functions.

Telephone Line

Ideally, the internal communicator should be connected to an ex-directory line

used exclusively for alarm communications.

If an exclusive line is not available and other apparatus is connected to the

line (for example, an answer machine), the internal communicator provides a

series connection with line divert for the other apparatus. When triggered, the

communicator seizes the line and disconnects the other apparatus. When the

communicator shuts down, it reconnects the other apparatus.

Note: If the telephone line is being used for a broadband connection then

Cooper Security Ltd recommend that you connect a suitable broadband

filter between the control unit and the phone line.

Three-way Calling

The control unit provides a three-way calling facility to make sure the internal

communicator can always use a shared telephone line.

To use this facility, the local exchange must provide the three-way calling

service on the customer's line.
