Provides Protection Against Intruders or Theft

Place this sensor near doors, windows, or other entrances to ensure that they remain secure. With its 100-foot operating range, the WT-433 gives you the peace of mind that locks or bolts simply can't match.

Easy-to-Install Unit Works with Skylink's Home-Security Systems
As part of Skylink's innovative home security system, the WT-433 requires no professional installation, registration with alarm companies, or expensive fees. You can install the unit yourself in just a few minutes to enjoy expanded protection in your home or office. This accessory is especially ideal for those who want to extend a current system to include all windows and doors.

Flashing Red Light Ensures the Security of Windows and Doors
The WT-433 works by sending a signal to the control panel or emergency dial whenever contact is broken, i.e. when an entrance or window is opened while the alarm is engaged.

In spite of the retailer claiming that my smaller triggers from previous SkyLink alarm would NOT work, they did!! But my newer alarm came with these triggers (2). I find them a bit bulky and unsightly so I prefer the smaller ones with a smaller battery.

About the best thing about THIS trigger is that you KNOW if it is not in its closed position by the little red light. If the light comes on, it is not fully closed and alarm will not arm this particular trigger.

Amazon Verified Purchase
I installed the SC-1000 and purchased a few of these add-ons. It does the job picking up the signal quiet nicely and easy install. I suggest you stock up on the batteries because you dont want these to fail in time of need so test them once in a while using the chime mode. Anyway, my main gripe is the I had these on my window and when it got warm, the double sided tape started unsticking I found a couple of these dangling from a couple of my windows when the sun was beating on it...I basically had to move it around - make the sun heat doesnt get to it or else the tape undoes itself.

Update: Screwed them instead, but if your're not willing to ruing your panels, they do sell double sided tape with better adhesive and will stay on. As for the alarm, I still use it and its great.

The Window/Door sensors are not the most attractive pieces of hardware you've ever seen. The silver terminals on the magnet are exposed instead of hidden within a housing. They do work very well though, which is the most important feature they could have.

Be aware that in most of the product photos they do not show you the wire that runs from the "wireless" unit to the magnets, but there is one. It's only wireless back to the main control panel. With some planning you could probably install this with the wire hidden, like in new construction. For those of us with existing door and window frames however it will be hard to completely hide the wire.

Also keep in mind that if you keep your windows locked, an intruder will most likely be breaking your window, not just sliding it open. I chose to use these units on my doors and am looking into the vibration sensors for the windows instead, but they might work for your application.

I attached a few photos at the top of the page, and you can see where I needed to modify my wooden door trim to get the sensors to sit flat. I used a Dremel to do this, and it wasn't hard but there was not another way for me to mount these and get them to work without modifying the trim around the door frame.

Overall they do work very well and I can accept the aesthetics of them for the price I paid.
