Hi Robert,

Thanks for the information. Can you tell me why I might require two of the motion sensors? Does one compliment the other or it is just for installing it in a second location?

NX-480 Passive Infared Motion Detector $89.00 NX-482 Sentrol Passive Infrared Motion Sensor ~$98.

Also does the RF module easily plug into the Elk M1 system? If I were to use a wired device like a door/window contact what kind of wire is recommended to connect the Elk system and the contact.

Thanks again for your time.

Neither. Those are just two different options.

There's a little cable that connects them together. Most sensors (except for fire alarm stuff) are connected using ordinary 2- or

4-conductor, 22-guage wire (aka 22/2 and 22/4). If your wire runs are exceptionally long you might use 20 guage wire but most normal size homes are fine with 22.

Fire alarm sensors require use of cable rated for "power limited" fire alarm circuits. Most of the time 18/2 or 18/4 fire cable is good.

Note: Even on magnetic door and window sensors which only require 2 wires I usually use 4. That way if a single conductor breaks (say, froma staple gone awry), I've still got an extra pair.

Have you read the Group's FAQ lately???

Second location. It's a good idea (depending on the size of your house) to "split" the protection between the front and the back. You definitely want a motion covering any stairs to the basement or the second floor.

The RF module is wired to the Elk common control. It's usually recommended that you mount the unit as high in the home as you can (to ensure maximum coverage). I wouldn't mount the RF module inside the common control.

Standard 22/4 "Station Z" wire is fine. Some use two conductor, but that can be a pain (particularly if one wire "breaks").

There are a number of excellent online resources and dealers. Most have better pricing than Bass (and better service). Here's a good resource:

I would check out customer feedback (some sites have links to that) or the BBB before you make a purchase decision.

Good luck!!
