Then I feed the speaker wire through the small hole I drilled in the second window. I then drill a 3/16" hole where the tip of the paddle/spade bit has poked through. The other side of the jamb where the two windows are mulled together I drill the 5/8" hole until the tip starts to come through the window stop on the other window. The side that I want to mount the sensor on the wall I drill a small hole (3/16") right next to the casing on an angle.

I use a 5/8" paddle bit/spade bit and drill a hole in both sides of the jamb at 7 1/8" off the window stool. To start, if the existing windows are wood doublehungs, I remove the window stop on both sides of the window I will install the sensor next too. That way you have one wire marked with a blackline (usually) and the other wire is unmarked. I have 6 sets of twin doublehung windows and found the best way to install on both windows is to use a light gauge speaker wire. To install, you will need to trip the add-on switches or open and close the contacts. Please note that any switches connected to the contacts will install as a different zone into the console. It has a pair of contacts that allow you to wire in some other normally-closed (NC) sensor just like with the DS10A. The newer DS12A sensor can also be expanded. You can substitute any normally-closed sensor (NC) made for a wired security system. If either switch is tripped, the alarm will go off. You now have a loop of wire with two switches in it. Connect the free wire from the sensor module to the other screw terminal on the new magnet switch.

Get a length of wire attach it to the free screw terminal, then attach the other end to a screw terminal on the new magnet switch. To add a switch to a sensor, unscrew one of the two terminals and take the sensor wire out. Whenever the switch opens up or a wire is cut, the sensor sounds the alarm because power is not flowing between the terminals. Normally, one magnet switch is wired to the terminals. The magnet switch has two screw terminals on it.

It is pretty simple to add another magnet switch to a Door/Window Sensor. How can I add an extra magnet switch to a Door/Window Sensor?Ĭan I use another sensor with the Protector Plus like a water level sensor? Answer I have a double window or door do I need to use two Door/Window Sensors?
