I am looking for a simple intruder alarm system for a large house. Not really interested in remote access and monitoring or systems requiring computers to load up and configure. Need 4 x RKP and 19 x PIRs. No PAs or door contacts, though will want to use PA functions on all the RKPs. I really like the simplicity of setting up and using the Accenta control panel, but am I right in thinking that 8 zones are the maximum available for PIRs? I could easily group together 2 or 3 PIRs on some of the zones but that can make fault finding more tedious. Would appreciate you confirming number of zones available to PIRs on Accenta Gen4, also any suggestions for another product.

Have a look at the Texecom Premier range , 24 or 48, the installation manuals are very concise.The Accenta is only good for 8 zones.
