Yeah. I have the FM as well, and the range isn't as good as I would have hoped for.
Well, actually, the range is fine, but it's not too good in concrete buildings, or dealing with parkade type structures, let alone underground parking.
I don't know about my paging sensor -- I never connected it.
I also did the installation work myself, so I can't really complain there.
In general, though, as far as alarm features go, I liked my old system better.
One thing that really irritates me is that there's no way to get stuff out of the car once it's parked without having to restart the car, put in the key, release the e-brake, press the foot brake, reset the e-brake, and take the key out... It's cumbersome. I realise that it's there so that some idiot won't put the car in gear so that it starts moving unattended on a remote start, but it's irritating, nonetheless. You should be able to remote start the car, disarm and open the doors to get your stuff out, then re-arm the car, and remote shut-down. Because the car was running when it was re-armed, it ought to be able to stay in auto-start mode. Well, anyway, that's my biggest complaint... That and the parkade thing.
