I scetched out the system with the existing cabling and came to 24 wired zones and 2 wireless. To be honest, I would much rather opt in for wired PIR's and contacts since I already have the cabling and avoid dealing with batteries etc. The 2 points where I don't have wiring, use 2 wireless Impaq contacts - so the 8xpw would cover me and I'll have 6 wireless zones to spare should I need them for future - which won't be the case since I'll be 100% covered.Premier 48 elite
1 x 32xp-w address 1 or 8XP-W price and flexibility extra £20 and you can utilise more wireless zones without having to add another expander.
1 x 8XP (address 4)
Essentially, the below would be the way forward following all the help I received from all of you:
1x Premier Elite 48
1x Premier Elite SMK RKP (Satin Chrome)
2x Premier Elite 8XP
1x Premier Elite 8XP-W
7x Premier Elite DT PIR’s
17x Door/Window contacts
2x Premier Elite Impaq Contact-W
1x Premier Elite Odyssey 5e (external sounder and strobe)
1x Pyronix Twin Alert Internal Speaker Sounder
1x Premier Elite ComIP
1x 17Ah battery
Can I also have your input on contacts with the so called "magnasphere" technology? Are they worth it?
Let me know your thoughts please?
Thanks
