Step 8. Connect the

Internal Communicator

(i-on30EXD only)

The i-on30EXD version of 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,

see page 19).

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.

• 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.

Line Monitoring for the Internal

Communicator

The control unit provides a line monitoring

function to check that a telephone line

connected directly to the control unit is

working, and to indicate a line failure if it is

not. While enabled, this function continually

checks the line voltage to ensure that the

line is connected. If it detects a failure, the

system gives the Line Fault Response

selected in the Installer Menu.

Test Calls

The control unit can be programmed to

make test report calls to an ARC. "Static"

test calls can be programmed to occur at

set times or intervals. "Dynamic" test calls

occur 24 hours after the last call made by

the unit. See the i-on Range Engineering

Guide for details on how to program these

functions.

Statutory Information

Applications

The built-in communicator is suitable for

connection to the following types of

networks:

(a) Direct exchange lines (PSTN) supporting

DTMF (tone) dialling.

(b) PABX exchanges (with or without

secondary proceed indication).

Note: The built-in communicator is not

suitable for connection as an extension to a

pay-phone or to 1 + 1 carrier systems.

Approval

The built-in communicator is manufactured

to meet all European Economic Area

telecommunication networks requirements.

However, due to differences between the

individual PSTNs provided in different

countries, the approval does not, of itself,

give an unconditional assurance of

successful operation on every PSTN

network termination point.

The built-in communicator has been

approved for the following usage:

(a) Automatic call initialisation.

(b) Operation in absence of indication to

proceed.

(c) Automatic dialling.

(d) Modem.

(e) Serial connection.

(f) Multiple repeat attempts.

(g) Line status monitoring.

Usage other than approved usage or failure

to comply with the installation and

programming instructions may invalidate

any approval given to the apparatus if, as a

result, the apparatus ceases to comply with

the standards against which approval was

granted. Note the approval label on the

main PCB.

In the event of problems you should

contact your equipment supplier in the first

instance.

Ringer Equivalence Number

The Ringer Equivalence Number (REN) of

the built-in communicator is 1. As a guide

to the number of items that can be

simultaneously connected to an exclusive

line, the sum of the REN values should not

exceed 4. A standard telephone (as

provided, for example, by BT in the UK) has

a REN value of 1.
