Dial port:
The Dial Port sub-menu has several options:
6.9.1.1 Monitor cable
Sets the terminal to monitor the dial port using
in the terminal package box). This should be fitted
the 2-wire analog interface (alarm panel telecoms module) and allows the terminal to report any status
change back to the ARC. Note that this must be fitted at the panel end of the connection to be effective.
The ARC will also need to enable the dial port monitoring (Panel) from the ISA
software to receive alarm notifications on this status.
6.9.1.2 Report polling fail
Click to enable the terminal to drop the line voltage on the dial port connection
if it cannot poll over any configured path to the ARC. This lets the panel detect and report locally on the
keypad of the alarm panel that it has a line fault, so the site has local indication of a communication failure
(for EN standards).
6.9.1.3 Enable Ringtone
This feature lets you enable or disable the terminal simulating the PSTN ring-back tone to the dial port while
the connection is being made. Usually this can be left as the default setting but if you are having issues with
alarm panels not sending alarms, try turning this off.
6.9.1.4 Voice call alarm
This causes the terminal to send an alarm to the ARC if a call is made via the dial port connection. This alarm
is pre-coded as shown in the Default Alarm Message appendix and is in either SIA or Contact ID format
depending on the Pin Inputs setup.
6.9.1.5 Ring
If the alarm panel is expecting a ring cadence (pattern of rings and pauses) to detect an incoming call, you
can set this to «Euro» or «UK».
6.9.1.6 Dial tone
If the alarm panel is expecting a dial tone when it makes an outgoing call, set this to «Euro» or «UK».
6.9.1.7 PSTN Only
Sets the terminal to route all calls into the Dial Capture port to be routed directly to the PSTN interface, if the
EXT2 extension board is fitted. The number dialed is used for the external PSTN connection.
6.9.1.8 Telim conversion
The terminal can support the Telim protocol on the dial capture interface. This
screen lets you modify the default Telim to SIA alarm conversion by selecting
through the presets or to set to Custom and entering the required SIA code.
