Hi there. Thank you VERY much for this. (Appreciate there are rules around advice to non-pros.)
I'm confident about doing this - the consultant had the lid off the unit in front of me yesterday, and I have a schematic so I know where the module is.
(Also, if we do sign up for any kind of maintenance contract, we don't want the phone option)
Can I just confirm that removing the modem module definitely stops the unit polling for a phone line?
Also, am I right in thinking that I need the engineer code to open the unit, or I'll get a tamper alert? (Will obviously check it's the default code before opening)

Oh, and one more question (sorry):
Earlier post said "battery is there so that the system works when the power is lost."
At present, if power is down, the alarm sounds anyway.
Is the only benefit of a battery that you can turn the alarm off when there's a power cut?
Thanks so much for help.
