An important detail left out of the programming instructions... - I installed this sensor on my detached garage (walk thru) door and programmed it on a 6160RF keypad. It was fairly easy after watching a few YouTube videos. I ran into one major snag though. When I finished, it wouldn't work. It kept giving me an error. Come to find out after much research, the cover has to be on it during programming. The sensor knows if the cover is off and thinks someone is trying to disable it. Aside from that, not too bad. It works well. Review: Great Replacement Sensors - Works exactly as I expected. Easy to program and configure with my system. Excellent option when we replaced our entry doors and the installation company cut the wires from the old sensors ## Features - Honeywell Ademco 5816WMWH ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002MA8GKW | | Antenna Location | Security | | Battery Cell Type | Lithium | | Best Sellers Rank | #207 in Home Security Systems | | Brand | Honeywell | | Built-In Media | 5816 Transmitter, CR123 Battery, Magnet | | Color | Red | | Connectivity Technology | Wireless | | Customer Reviews | 4.5 out of 5 stars 855 Reviews | | Item Dimensions | 4.6 x 1.8 x 1.4 inches | | Item Weight | 3.2 ounces | | Item dimensions L x W x H | 4.6 x 1.8 x 1.4 inches | | Manufacturer | Honeywell | | Manufacturer Warranty Description | 2-Year Limited | | Mfr Part Number | 5816WMWH | | Model Number | 5816WMWH | | Power Source | Battery Powered | | UPC | 781410171596 | | Unit Count | 1 Count | | Video Capture Resolution | 720p | ## Product Details - **Brand:** Honeywell - **Color:** White - **Item Weight:** 3.2 ounces - **Item dimensions L x W x H:** 4.6 x 1.8 x 1.4 inches - **Video Capture Resolution:** 720p ## Images ![Honeywell Ademco 5816WMWH White Door/Window Transmitter w/Magnet - Image 1](https://m.media-amazon.com/images/I/51pqLWe0m9L.jpg) ![Honeywell Ademco 5816WMWH White Door/Window Transmitter w/Magnet - Image 2](https://m.media-amazon.com/images/I/51gl1Bg0wfL.jpg) ![Honeywell Ademco 5816WMWH White Door/Window Transmitter w/Magnet - Image 3](https://m.media-amazon.com/images/I/51gFb0rK8YL.jpg) ![Honeywell Ademco 5816WMWH White Door/Window Transmitter w/Magnet - Image 4](https://m.media-amazon.com/images/I/31QFWvyVXGL.jpg) ![Honeywell Ademco 5816WMWH White Door/Window Transmitter w/Magnet - Image 5](https://m.media-amazon.com/images/I/31bbM2q0sUL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Vista 20P Alarms System.
