SystemTesting
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
RedandYellow 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. SeeAppendix 1.
1. PoweruptheDualCom,the unit will initialise. This willtake20seconds 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 testboth reporting paths to theARC, momentarily short the test pins on
the DualCom see Fig 1 & 2. This will cause DualCom to send a test signal
to theARC on both the PSTN telephone path and GSM radio path.
Oncethetest pins are shortedthetwo communication LEDs willilluminate,
(Red for PSTN and Yellow for GSM). During communication the LEDs will
flash to indicate the progress of the call, seeAppendix 1. When a path has
successfully communicated with theARC, the associated LED will go off.

two test calls
Ensureafterthe test that bothLEDs are off; this willmean that the testcalls
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
circuitsare 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
returntotheir quiescent value.
