We have eircom and the reason why they wont unless you replace with them is because they want you to buy the alarm off them which i paid 900 euros for and then you pay the monitoring montrhly, but its there way of getting you to buy an alarm off them. Would you not feel comfortable just turning it on and off yourself? Im goin to be leaving eircom, and just get a fella to put one in and turn off and on myself and no more monthly bills. They also charge you for servicing of the alarm.
