atcomsystems.ca/forum Forums Wiring - Telecom Carriers - Trunks & Services Security, Alarms and Paging pre wiring new construction how to wire double hung windows

builder asked to us to pre wire new home for future alarm ( we run the cable so if new owner wants alarm its there )

we ran cable to all doors and windows but the windows are double hung so the contacts cant go on top so we ran cable to bottom of windwows since thats the only place I can see contact working

drywall goes up next week so I can move the cable if I done wrong

windows look like this :

You should wire it for 2 contacts per window, one in the top and one in the bottom.

In a perfect world both cables would be home ran to the control panel but in reality just run them to an area that will be accessible after the drywall is installed and the alarm installer can series them together and run one back to the panel.

we would only need the second cable on the ones that open from both top and bottom right ?

its small enough we can pull the second cable's tomorrow where need be

thanks

Yep, that's it. I always like to run 4 conductor wire (2pair) so I will have a spare pair.

Install a motion

Yep, do it like TT says. I actually just series them as well.

Normally if I'm coming from the ceiling, I hit the top of the window first, loop it and continue to the bottom. When I prewire, I always drill a 3/8" hole on those and leave the wire in it.

On finish, I find you can normally use a 3/8" concealed contact with a different magnet. I use those n-dym magnets (look like a washer). You can buy them like this or I just stock the magnets separately (they come in a tube of 12).

Good point about the motion detector TP.
And we should add the power cable, the keypad cables, the siren cable, the telephone cable... what am I leaving out TP?

Oh, I just took it for granted that skip ran all those other wires. I was being sarcastic about the motion. I hate doing windows, they are a PITA, especially double hung.

I always tell the customer one motion will probably cover all the windows in that room. But if you want protection at night, in the "stay" mode, you need to contact those windows that are easily accessible from the outside.

My basic prewire consists of doing every door and a few motions for interior traps. If they want windows done, it's always extra. Did I mention they are a PITA!

Skip, you still here? Hello?
I think we scared him off TP.
Actually, now is a good time to make sure you have all of your bases covered.

already ran one pair , where just doing the prewire , no contacts or panel.

can I do the loop with a single pair or is it best that each contact have its own ?

seems like one pair looped would work

conceled contacts aren't going to work here concrete construction no window access from the side top or bottom

also what do we need from the panel to the keypad ?
we ran two , single pair (two pair total )

its a fairly small three bedroom home and I want to do it right , I have to go back and pull some network cables tomorrow so pulling a little more alarm at this point is not that big a deal .

I think most keypads now are just 2 pair from the panel.
