Right, thanks to Andy I have just bought the Texecom speech and text dialler unit. I got it brand new but cheaper than the price quoted - we don't need the text function but it was cheaper than the none text version.
One problem I have is that since the talk through system will obviously only work close to that unit, texecom sell a RMU (remote microphone unit) but can't find one anywhere!
Since the alarm box only has two outputs other than the siren, speaker and strobe (all used) I don't see the point of having the smoke detectors wired in. This is because:
1) I find it difficult to find kit that would work with the alarm
2) If we went for this, the smoke detectors would probably have no alarm, if the alarm sounded my Grandpa might not hear it (anybody who has been in a house when the alarm has gone on, it's not always obvious it's yours even if you're fully awake!) So separate speakers/sirens would have to be fitted. Maplin had some great ones with stobes but they don't sell them anylong annoyingly! Also it would be hard to put them onto outputs and it would mean that the dialler would only have: "PA has been pressed" or "FIRE, BREAK IN OR FALSE ALARM" which defeats the purpose IMO and if there is a fire, not much point us knowing, best my grandpa knows best(!!!) and can get out then think about the fire brigade (who are 100m down the road although sadly it's one of the ones where they page the fireman, there's only a few who work their full time, I always hoped the few who work there full time would jump in, drive up, do what they can until everybody else arrives.)
So I think we're going for these interlinked wireless ionisation alarms:

It means no annoying wires everywhere and although not mains powered which is slightly annoying, I know that my grandpa would change the batteries. He doesn't mind paying the extra for an optical system, however, from what I can find, ionisation is only worse since it is more sensitive and open to more false alarms. Optical can miss small smoke particles. Any day of the week in a domestic use, false alarms are better than it missing small particles. Can anybody confirm this? I feel bad buying the cheaper version for the sake of £10 if it is better....(we're buying 3-4).
Since he already has a CCTV access system on the front door/drive (it covers the full front of his property except the extremes, front garage doors and front window though you have to pass the CCTV whatever you do to get to either!) I was looking at a dummy camera as you know which will be fixed to the side of the house and aimed down to where the hidden CCTV camera is pointed. Also addition of
stickers. Would this be believed:

Bidding for some excellent panic buttons. I believe maplin price is stupid £4 each, I am hoping to get these more sturdy units for £2 each and buy 4. Switching of these = alarm unit on, voice dialler input 1 on "PA has been pressed".
I know what pressure mat to get but need to get into the house first to check if it is a good idea and check what else I may have missed since it's all from memory of his house. Think I might stick a door sensor on the conservatory/garage-workshop door, 1) will mean he HAS to close and lock it when the alarm is set
2) Once he is in the conservatory he only has the rear PVC door between him and the criminal.
Still looking for gates.
Locks.
These are the hardest for me.
