Technical Support & Web Site - CSL DualCom GSM Mk1 Installation Manual

Troubleshooting (continued)
Q. What if the GSM signal has not been received by the Alarm
Receiving Centre ?
Check that the NVM is fitted has been correctly programmed.
Check that the SIM Card is fitted has been correctly programmed
i.e it is enabled for 'Data'.
Check, using the Signal Strength LEDs (Red & Green) that the radio
signal is sufficient and the GSM path status = OK.
Check with a meter that the voltage supply to the Dualcom is 13.6v or
more and does not dip when the DualCom is signalling.
See Appendix 1 for GSM fault indications. These will help diagnose
radio path problems.
