The approvals listed are wrong:-
EN50131-1 is a system standard, nothing to do with components.
EN50131-2-4 is for dualtechs, not PIR's, i don't see any dulatechs on your website.
No EN standard for the control equipment.
No mention of PD6662 the UK scheme for EN and BS standards.
To have any validity the certificate and testing must be carried out by a laboratory that complies with EN45011 and ISO67, this should appear on the certificate and the test reports.
The standards you listed before are all legal requirements to apply a CE mark, so these would be expected.(although not guaranteed.)
Not trying to slate your product, but the facts you have presented are incorrect, and potentially misleading.
Question:- do any of your products have removal from mounting tamper detection?
