5.3.5.4 Cellular communication tests
The terminal will send a test poll and test alarm message to the ARC to check the
Ethernet connection.
If these are not successful, the terminal will display the failure and possible
reasons. See section 5.3.1.
PSTN Setup & test
5.3.6.1 PSTN connection test
If the PSTN expansion board (EXT2) is fitted and the PSTN network interface is
selected, the terminal will now check the PSTN connection by checking the line
voltage.
If PSTN is not connected, please check the cable and connection to the PSTN line. After reconnecting, it can
take up to 30 seconds to detect.
5.4 Further configuration settings
Dial port check
If Monitor Dial Port has been selected at the start of the wizard, the terminal will
perform a check to see if the 18K ohm resistor has been fitted. If Monitor Dial
Port has been enabled in error, the terminal will report this. In that case,
uncheck the "Monitor Dial Port" checkbox.
Pin alarms
This provides the option to use pin alarms which are the Pin inputs, and which
can be used for SMS messaging or alarm signaling.
Click «Yes» to use the pin alarms or «No» to continue.
5.4.2.1 PSTN: Alarm Setup
If you have selected to use the PSTN interface, you will be asked to enter the
telephone numbers of the PSTN receiver(s) at the ARC.
Click <<Continue>> when done.
5.4.2.2 Pin format
The Pin format screen is then displayed.
Click the appropriate tick-box to select which pin alarm format to use. SMS is
only available on terminals with cellular capability.
Note: If you have selected PSTN network interface (EXT2 expansion board fitted) then the option
for SIA will not be available as this is not currently available over PSTN.
When done, click «Continue».
