Hi,
Short version: I am moving my house automation off the HAI Omni IIe (in expectation that the unit will continue to degrade - its been in service for about 13 years )
BUT I am trying to leave the alarm functionality on the OMNI.
I expected to be able to continue to use the PIRs already in the house as inputs but have hit an issue.
They were wired as per the attached with my new additions shown in red.
On testing I noticed the PIR zones did not switch cleanly - I was expecting 0V and then 12V across the terminals
After fiddling around I discovered I could get this by using the (previously unused) 2nd contact from the alarm (Yellow in Diagram).
So far so good; then I wired it in for real and the OMNI is signaling 'Trouble'
What I can see for Loop Values is
WithOUT the new connection for Home Assistant on Zone+
Normal Not triggered (Closed) 148 Secure
Triggered (Open) 251 Not Ready
With the new connection for Home Assistant on Zone+
Normal Not triggered (Closed) 148 Secure
Triggered (Open) 170 Trouble
and measured current to the 12V-to-3.3V converter is 2ma
R=V/I 12/.002 = 6000OHM
Does anybody have any idea how to alter this circuit so that I can have the best of both worlds ?
We live in the country and now reside here permanently - the handfull of sensors are inside and I cant see anyway anybody could get in and tamper with them without setting the alarm off.
So I am happy to lose the 'tamper' concept but I dont understand the nuances of 'Trouble' vs 'Not Ready' when it comes to the EOL Resistor.
Thanks for listening
JC
