Hi All,
I'm having a problem with some new PIR's, https://www.security.honeywell.com/u...02-EN_DS-Z.pdf
For some reason when I connect them in the normal way and when they activate they seem to be sending the output hundreds of times per second to the extent that Cortex can't keep up.
I'm surprised as they are described being 'entry level'. The strange thing is that the one's that I have used elsewhere which were left over from an alarm installation work perfectly. The only difference that I can see is that my older ones are described as having a dry contact relay; the new ones say they incorporate a 40 ohm protective resistor. Could this be the problem ?
I would really to use these new ones as they are very much more sensitive than the older ones.
