System Testing
Ensure you have informed your Alarm Receiving Centre that you are
ready to test your DualCom.
Note: If the NVM is an incorrect type, is faulty, fitted incorrectly or has been
incorrectly programmed (including being blank or un-programmed), then the
Red and Yellow Communication LEDs will flash alternately.
If there is a problem with the SIM Card or the GSM radio module, the Yellow
Communication LED will flash. If there is a problem with the PSTN telephone
line, the Red Communication LED will flash. See Appendix 1.
1. Power up the DualCom, the unit will initialise. This will take 20 seconds with
the GSM LED On, the PSTN LED Off, and the Signal Strength LEDs Off.
When ready, the GSM Status LED will flash on/off slowly and the Signal
Strength LEDs will show the signal strength,
2. To test
both
reporting paths to the ARC, momentarily short the test pins on
the DualCom see Fig 1 & 2. This will cause DualCom to send a test signal
to the ARC on both the PSTN telephone path and GSM radio path.
Once the test pins are shorted the two communication LEDs will illuminate,
(Red for PSTN and Yellow for GSM). During communication the LEDs will
flash to indicate the progress of the call, see Appendix 1. When a path has
successfully communicated with the ARC, the associated LED will go off.
Both paths will send a test call. The Alarm Receiving Centre should receive
two
test calls
Ensure after the test that both LEDs are off; this will mean that the test calls
on both paths are complete.
3. Now trigger all the used inputs on the DualCom. This should be done by
Setting the Control Panel and triggering an alarm condition. If P/A or Fire
circuits are being monitored these should also be triggered.
Note : When alarm calls are made, both GSM and PSTN paths are
activated, but only one alarm call will be received. This will be from
the path that is the first to send the alarm call to the ARC.
4. Contact your ARC to confirm that all signals have been received. Ensure
that all ‘Restore’ signals are received when the DualCom input terminals
return to their quiescent value.
