Looking at using some Takex PA-6612 PIR's for occupancy detectors because they are supposed to be pet resistant. Not being used for security role. The literature shows 7 contacts. Two for power and two for dry contacts. However, there are 3 more and I am curious how to use them...if I can. Two are labled for "Tamper" and one is for "M/C Memory".
I am using an HAI OMni Pro II. What are the 3 remaining connections for and is there any function the might play for me in my Omni II setup?
 
Tamper is for security, its basically for protecting the pir against tampering. For HA all you need is your 4 wires - 2 power and 2 zone.
