ashjack98 Posted February 22, 2007 Share Posted February 22, 2007 I have been given an Aritech DD105c PIR for a project to connect a camera to a PIR - the problem I have is that apart from the power I don't know how to wire it - what actually happens on the pin-outs when the PIR detects movement ? I have tried wiring it various ways and have had the multimeter on the pins but nothing ever seems to happen, could the PIR be broken ? It definatley works to some extent as the red LED strobes.... Any help and advice gratefully received. Link to comment Share on other sites More sharing options...
Eggy Posted February 22, 2007 Share Posted February 22, 2007 There should be a sticker just above the terminal block on the backplate. Link to comment Share on other sites More sharing options...
C.Simmons Tech Services Posted February 23, 2007 Share Posted February 23, 2007 connects as follows(left to right) 1=0v 2=12v 3 and 4 Alarm N/c contacts 6 and 7 Tamper contacts Make sure jumper 2 is on the bottom 2 pins of the 4k7 resisitors will be in use Chris Link to comment Share on other sites More sharing options...

ashjack98 Posted March 1, 2007 Author Share Posted March 1, 2007 Thanks for the advice folks, I get the clicking sound from the relay, but apart from that there is nothing at all happening at the contacts, I guess it must me a faulty unit, in which case I'll buy something else - can anybody recommend a PIR that would be sensitive enough to detect a mouse sized object with both heat and movement detection ? The PIR would only be required to 'look' at an area of about 6ft square. (as you have probably guesed, I know very little about PIR's - but have already made the equipment to activate my digital camera, all I need is a small electrical pulse to turn it on...) , Ashley Link to comment Share on other sites More sharing options...
Guest Posted March 1, 2007 Share Posted March 1, 2007 How are you testing it? It's a clean pair of contacts, nothing appears on the alarm contacts, they just open and close. Link to comment Share on other sites More sharing options...
PJF Posted March 2, 2007 Share Posted March 2, 2007 I have fitted thousands of DD105 and I doubt its a faulty unit, are you sure your a in the alarm pair. Top tip: if you ever catch fire, try to avoid seeing yourself in the mirror, because i bet thats what REALLY throws you into a panic and dont forget the one thing you cant recycle is wasted time.

ashjack98 Posted March 7, 2007 Author Share Posted March 7, 2007 I have a battery & bulb test circuit (3v) and I'm connecting the open ends of the wires to alarm pins 3 & 4 figuring that the bulb would light when the alarm triggers.... but it never does. As Chris replied the other day " 1=0v 2=12v 3 and 4 Alarm N/c contacts 6 and 7 Tamper contacts Make sure jumper 2 is on the bottom 2 pins of the 4k7 resisitors will be in use J1 & J2 are in the positions indicated on the diagram on the PIR (at the top) - if I move to the bottom then the LED never lights up...

The PIR will be loads better as I can then scan a small area rather than having to rely on a beam being broken.
