thanks! Will have a look now

Thanks for getting back to me. Sorry for noob questions...what's an ATA? As for control panel, I dont believe the detectors I have (around 10 years old) are compatible with new panels. Just can't afford a big expenditure on the alarm right now...otherwise would have looked to upgrade and avoid the current issue (no phone alerts)

Hi. My new phone line is voip so my visonic can't call me if it goes off. I found a gsm module on ebay, but the seller says that as my alarm is v.old, adding the module could damage the unit due to the power down. I asked an installer too and he just say "at your own risk" 1/ Is there much risk of damaging the whole setup? 2/ Is there a gizmo out there which can connect to the visonic phoneline output and turn it into gsm? Thanks
