Hi everyone
Long story short, I got a high end optex outdoor PIR at a bargain price but problem is it's the wireless version designed to be fitted to a small transmitter.
The PIR does have all the terminals as you would find in the same wired version. The big difference however is that the alarm output in the wireless version is controlled by a very low current solid state form c relay with max 10VDC 0.01A rating. Where as the wired version has a real mechanical on/off relay that can work with 12V cables over a long distance.
I called Optex Technical and they told me that hard wiring the wireless PIR with my 15m long 12V cable may give erratic behavior as the solid state relay in the wireless is not a true on/off switch.
I was coming up with a work around and thinking of adding an intermediate relay system connected to the PIR alarm output, and then connecting the 12v alarm cable to the other end (N.O) of this mechanical relay.
Do you think this will work and be reliable? Basically the input side of the intermediate relay would need to be very sensitive to low current (10mA max. Rating of PIR) so that it would detect the trigger from the PIR alarm output and then pass that on clearly as a mechanical ON state to the 12v 15 metre long cable going to the alarm panel.
Any link to a simple relay that would work? Ideally needs to be a 9-10VDC input relay as the wireless PIR alarm output rating is max 10VDC 0.01A max.
Thanks
