Honeywell Home 5816WMWH Door/Window Contact
The Honeywell Home 5816WMWH Door/Window Contact is a wireless magnetic contact transmitter designed to monitor doors, windows, cabinets, and other openings as part of a compatible Honeywell Home or Resideo 5800 Series alarm system. This sensor helps detect when a protected opening is opened or closed and sends that signal to the alarm panel for security monitoring, chime notifications, automation rules, and alarm response.
Operating on the 345 MHz wireless frequency, the 5816WMWH is one of the commonly used Honeywell 5800 Series wireless contacts for residential and light commercial alarm systems. Its white housing, included magnet, built-in reed switch, and wired contact loop support make it a versatile option for replacements, upgrades, and new alarm installations.
Compatible Alarm Systems
The Honeywell Home 5816WMWH is designed for compatible Honeywell Home and Resideo alarm panels that support 5800 Series wireless door/window transmitters. Compatibility should always be confirmed before ordering, especially when adding this contact to an existing alarm system or replacing an older wireless sensor.
Door and Window Protection
This wireless contact is designed to monitor the opening and closing of protected entry points. When the door or window opens, the magnet separates from the sensor and sends a signal to the compatible alarm panel, allowing the system to respond based on the programmed zone settings.
Built-In Reed Switch and Wired Loop Support
The 5816WMWH includes a built-in magnetic reed switch for standard door and window monitoring. It also supports a wired closed-circuit contact loop, giving installers added flexibility when connecting a compatible external wired contact or protecting an opening where the main transmitter body cannot be placed directly next to the magnet.
White Surface-Mount Design
The white surface-mount housing is designed to install on doors, window frames, trim, cabinets, closets, and other openings. Its standard white finish helps blend with many common residential and commercial interior surfaces.
Case Tamper Protection
The 5816WMWH includes case tamper protection to help notify the alarm panel if the transmitter cover is removed. This helps support proper system supervision and makes the sensor a dependable option for monitored alarm installations.
