How to Wire a Motion Detector to an Alarm Control Panel

Need a tutorial on the installation process of putting together a DIY alarm system?  Step into Matt’s Knowledgebase classroom.  Our Tech Manager Matt Apperson explains how to wire a motion detector to an alarm control panel.

Here is that transcript from the video:

All right.  Well, here we go.  Okay.  So today we’re going to wire up a motion detector to the DSC control panel and this particular motion is basically almost the same one you get in most of the kits.  So we’re going to go ahead and wire this up to a DSC control panel and we’ll get this together here.

So usually what you’ve got to have is you’re going to have to have four wires to the motion detector, two wires which are going to carry the power and two wires that are which going to accommodate the zone.  So what we’ll do is usually we have of our four conductor, a red, black and a white and a green and I like to stay with the red and the black for the power.  So we’ll take our red and black here and in the motion, we have a 12 volt and a ground.  So I usually use the red wire as positive so we’ll go ahead and wire up our 12 volt to positive into the 12 volt there and then I’ll use our black wire here for our ground wire and we’re going to wire that right into the ground.  Tighten that down.

And then the other two wires here, the white and the green, this is what we’re going to use for the zone.  There’s no polarity on these two wires so it doesn’t matter which way they go and on the motion, we’ll have an N, C and a C or if it’s a different brand in motion you may have something that might say alarm or it may say RR or I think that’d be about it really but we’re going to wire up our two wires into the N, C and the C and then we’re going to tighten these down here.

Okay.  So that’ll take care of it for the motion detector.  We have our two wires for power and our two wires for zone and we’ll just feed our wire back through this so we can put the cover back on it.  Take our cover here and put this back together and there we go.  So that will be that.

And then we can go ahead–and now we’re going to go ahead and wire this up to our control panel.  What we have here is we need to get our power from the control panel which is 12 volts DC.  So we’re going to take our yellow and our–our red and black wire here and we’re actually going to get it off the auxiliary plus and minus circuit.  So we’ll take our black wire and put that in auxiliary minus and then we’ll take our red wire and put that in the auxiliary plus.  There we go.

All right.  So now we need to wire these other two wires here, the white and the green that we currently hooked up to the normally closing common and the motion into a zone on the control panel.  So for this example we’re going to go ahead and use zone one and common and you can see here I have a resister to shorten that zone out.  So we’re going to go ahead and take the resister out and we’re going to go ahead and use this particular resister for wiring this up to the control panel.

So being as it’s a normally closed device, our resister needs to be in line because we would need to create an entire loop back to the control panel, so from the zone, through the motion back into the calm.  5.6K of resistance and one resister per zone.

So in this case what we’ll do is we’re just going to twist our wire up to the one side of the resister and then we’re going to take the other side of the resister and put this into the zone one terminal and then what we’ll do is we’re going to take our second wire and we’re going to put it directly into the calm terminal.

Okay.  So this right here will give you your loop.  Now you can cap this in several different ways.  You can actually solder this connection here.  We have wire crimps that you can use.  Put it on and just crimp it down.  We also have–or you can get like wire nuts or, you know, things like that, anything you can kind of be creative with to make sure that you secure this connection.  We’re not going to secure this for–today so.

So what we need to do is that’ll take care of the motion to the control panel and then pretty much what we do is we would program the zone accordingly so how we would want this particular device to function.  We’re going to go ahead and we would program the panel to either make it be off when you arm it to the home mode or, you know, give you a delayed time or be an instant zone if it’s in an area that you’re not going to be in while the system is armed and, you know, if you plan on arming this while you’re at home, this device can be programmed to be activated while you’re at home, say if you had a basement or a downstairs level that you knew you weren’t going to be in and so as far as the motion goes, that’s going to be about do it for today.
