Product Highlight: Wireless Recessed Door ContactsPosted By Michael Goris
Hi DIYers! Today, we're taking a look at our best wireless recessed door contacts. These devices are great for when you want sensors that are completely hidden and not visible when the door is closed. They take a little bit of extra effort to install, but it's worth it for many users!
When you have a recessed contact, you actually need to drill holes into the door and its frame. The hole in the frame is larger and sized to support the main sensor. The hole in the door is smaller and designed to support the magnet. Some recessed contacts use extremely small magnets that can be mounted without drilling holes. There is also the Honeywell 5800RPS, which uses a plunger switch rather than a magnet.
The key with wireless recessed contacts is knowing which ones are compatible with your system. This depends on the wireless receiver that your system has installed. If you have a hardwired panel with no wireless receiver, then you cannot use wireless sensors. It's really no different than any other wireless sensor. You might also want to know the size of the holes you will need to drill. For your convenience, we put together a nifty table that outlines nearly all of the information you could want:
