For those who want their security system contacts to be aesthetically pleasing!! This plunger is specially made to be concealed in the hinge-side door jam by a closed door. The captive magnet in the plunger triggers an alarm event when the button is depressed.

Simple to install and requires basic drilling skills to accomplish. Using a Drill with a 3/4" Forstener Bit and a 1/4" Wood Bit (for antenna insertion), it's a snap! And with it's 3.0V Lithium Coin Cell Battery; the ION plunger let's you set and forget it for at least 5 years without having to change the battery.
