Essential Info

A bulky home security system can be an eyesore. Adding to that stress is hard wire installation permanently altering the aesthetics of a room, door or window treatment. With its wireless connectivity and fully concealed platform, however, the iON Security Plunger is a door security sensor that finally eliminates these pesky inconveniences. A captive magnet within the Plunger activates a reed switch when the plunger is depressed.

Also available for GE wireless receivers. Please see the 3/4" Forstener bit, recommended for installation.

Smarthome does not accept defective returns for this product. You will need to contact the Manufacturer (or Supplier) directly for all warranty issues.


More Info

Installing the product requires just three tools:

1. Drill
2. 3/4" Forstener bit
3. 1/4" wood fit (for antenna insertion)

Meant to fit snugly on the hinge-side door jamb and to be concealed by the closed door, you simply drill a 1" deep hole using the 3/4" Forstner bit, followed by a 1/4" hole drilled into the center of the cavity where the antenna must be inserted. Once you feed the antenna into the 1/4" hole, you merely press and secure the iON Security Plunger into the open cavity, and your instillation is complete!

From then on your fear of any burglars spotting your motion sensors and finding alternate and less-secure entryways into your home or commercial space can be forgotten, because this 3 step easy-to-install package is not only virtually invisible to the naked eye, but it uses a sophisticated wireless transmit that extends to 500 ft of the wireless receiver - making it an ideal choice for installing in just about any corner of your home or office.

The iON Security Plunger's battery-life is another one of its convenient features, as its 3.0V Lithium Coin Cell Battery has an average life-span of about 5+ years, ensuring you and your family's safety will not be compromised by the vexing and easily forgettable task of constantly having to replace your battery.


  • Dimensions: 0.33 in. deep x 0.75 in. diameter
  • Fully concealed in wood door frame
  • Compatible with all DSC Wireless receivers
  • 500 ft open air wireless transmit range
  • Long-life Battery - 5+ years (avg)
  • Important notes:
    Smarthome does not accept any returns for this product. If defective, you will need to contact the manufacturer directly for all warranty issues.

    Easy to install, works great. Better than the window counterpart because it adds less thickness between the door and the frame.

    Works great until you have to remove them to replace a battery. I got over 6 years on the original batteries. Over time, my wood door jambs swelled around the units, freezing them in place. I had to destroy them just so I could remove them. Now that they are removed, I don't need to replace the costly batteries. Oh jolly. Now I'm looking for surface mount units that take AAA batteries.

    Easy to install and works perfectly. Can't complain about anything.
    DAVE -- eugene, OR   10/8/2012
    Easy to install, paired right up to my DCS system. Be aware that they assume you will have a wall cavity on the hinge side of your door. Both of my exterior doors had many studs in a row and a regular drill bit would not reach deep enough to make a channel for the antenna wire. If this is your situatiion, you'll need to use a nonstandard long reach bit.
