Troubleshooting

Q. What if the VDN radio path signal has not been received by the Alarm

Receiving Centre ?

Check that the NVM is fitted & has been correctly programmed.

Check with a meter that the voltage supply to the Dualcom is 12v or more

and does not dip when the Dualcom is signalling.

Check, using the Signal Strength LEDs (Red & Green) or the CS1052 that

the radio signal is sufficient and the VDN path status = OK.

Contact a Help Desk or use Direct Check to measure the signal strength

that is received at the base station.

Check the aerial for connection and insulation.

See Appendix 1 for VDN fault indications. These will help diagnose radio

path problems.

Q. What if the Telephone Path signal is not received by the Alarm

Receiving Centre ?

Check that the NVM is fitted and has been correctly programmed, i.e.

PSTN enabled, correct telephone numbers etc.

Check that the PSTN line is properly connected. Check with a meter that

approximately 50 volts DC is present across the PSTN terminals marked A

and B. Connect a telephone to the PSTN line and make a call to the ARC

to ensure that the PSTN line is fully functional. Remove telephone after

test.

Disconnect any other equipment that is using the same PSTN line to en-

sure that it is not inhibiting the Dualcom.

Check that when the Digital Communicator is triggered, the voltage across

the A and B terminals drops to between 6 and 12 volts DC.

Ensure that ‘call barring’ to the ARC Receiver telephone number has not

been set on the PSTN line used by Dualcom.

See Appendix 1 for Line Monitoring indications. These will help diagnose

line problems.
