•
Control Tone of Ring
: If enabled, the dialler will send the voice message only when the ring tone is
present; if not enabled, the voice message will be sent as soon as the number is dialled.
•
PABX Branch
: This signals to the PSTN module that it is connected to the telephone network through
a PBX and not directly. When enabled, the module inserts the digit indicated in
Access digit
before
the number to be called.
•
PABX Pause (sec)
: This sets the duration of the dialling pause between the
Access digit
and the
number to be called.
•
Access Digit
: This is the digit to be dialled before the number to engage the external line, if there is
a PBX.
•
Test PSTN Line Availability
: This enables the periodic check of the PSTN line. After the established
number of consecutive tests has failed, a "PSTN Failure" event is generated. The periodic check time
interval and the number of consecutive failed tests are set in
Advanced Settings
.
The actual time between the failure, or tampering, and the generation of the "PSTN Failure" event is
determined by both the time interval between tests and the number of consecutive tests that must fail.
For example, if the time interval is 60 minutes and 5 consecutive tests have to fail, the signal may
occur, depending on the time between the failure and the first test, from 4 to 5 hours after the failure.
IMPORTANT!
If the control panel is the first device on the telephone line, as recommended in
the
Installation Manual
, the line test will interrupt any telephone calls in progress. This is
because the control panel engages the land line for a few seconds for each test.
Click on the
Advanced Setting
button to display and set the following parameters:
•
Interval of PSTN Line Availability (min)
: This can be used to set how often in minutes the
Interval
of PSTN Line Availability
is run.
•
Number of Retries
: This can be used to set the number of consecutive failed attempts after which
the "PSTN Fault" event is generated.
IMPORTANT!
To ensure conformity to EN 50136-2, it is necessary to enable the PSTN line
presence test and to set the PSTN line presence interval and number of attempts for a total of
not more than 30 minutes if 25h.
•
PSTN Test Mode
: This can be used to choose when to run the PSTN line presence test. The possible
options are:
o
always
: The test is carried out continuously at the frequency defined with
interval of PSTN Line
Availability
. With this setting, the test may cause an ongoing call to be interrupted.
o
System Armed
: Again in this case, the test is run at the frequency defined with
interval of PSTN
Line Availability
, but only if the intrusion alarm system is TOTALLY armed. A partial insertion does
not activate the PSTN line presence test. With this setting there are no interruptions of ongoing
phone calls (it is assumed that when the system is fully activated no one is present to make phone
calls). The first test is run when the system is armed.
•
Duration of DTMF Pause (msec)
: This can be used to set the time, in milliseconds, of the pause
between a DTMF tone and the other. To be modified in special cases only.
•
Duration of DTMF Tone (msec)
: This can be used to set the time, in milliseconds, of the sent DTMF
tone. To be modified in special cases only.
•
Duration of DTMF Pause Contact-ID (msec)
: This can be used to set the time, in milliseconds, of
the pause between a DTMF tone and the other when used for a communication with an alarm control
room.
•
Duration of DTMF Tone Contact-ID (msec)
: This can be used to set the duration, in milliseconds, of
the DTMF tone sent when used for communication with an alarm control room.
•
Delay for composition of Contact-ID Message (msec)
: This can be used to set the time, in
milliseconds, of the message composition delay to an alarm control room after receiving the ring tone.
