The original system is connected to my BT line only.
Thank you. Look forward to this. Would also be interested in what's required to fit the optional GSM module.
OK I have now got the information for you, not good news I'm afraid, the Galaxy 2 needed the GSM module to allow you to send texts to a mobile, however this item has now been discontinued (2011) see attached link ~~ http://www.security.honeywell.com/uk/intruder/documents/CPIB034_G2_GSM_Module_%20A231_DISCONTINUATION.pdf ~~ there is however listed a replacement which you might be interested in or it would seem that you can get the module from this company ~~ https://www.securitywarehouse.co.uk/catalog/microtech-galaxy-gsm-module-p-701.html ~~ Thanks for using JustAnswer ~ Ian
Thank you Ian. That is very useful information.
