Sure, the rest of the system has had quite a bit of thought and I am confident in how we want it to operate, I just asked about the parts I was unsure about.
I think I know what I need to order now so that should be fun:
1 x Texecom Premier Elite 88 Control Panel
4 x Texecom Premier Elite LCDLP
4 x Texecom Premier Elite Odyssey 5 External Sounder
1 x Texecom Premier Elite PSU200XP
2 x Texecom Premier Elite 8XP
A bunch of Texecom Premier Elite AMQD for the PIRs
A bunch of Texecom Premier Elite Proximity Tags
A bunch of magnetic door contacts
2 x batteries for the panels
I think this system will satisfy the requirements I set out in the original post, opinions are always welcome though.
If anyone thinks I have missed anything please let me know
