Honeywell Home 5818MNL Wireless Recessed Door/Window Transmitter
Disappears into the door frame.
A recessed wireless transmitter with a built-in reed sensor that gives concealed protection for doors and windows. Once installed, it virtually disappears.

A visible sensor tells everyone where your protection is.
Surface-mounted contacts are easy to spot on a door or window. A recessed sensor keeps your security system's coverage out of sight.
Concealed protection, simple upkeep
The 5818MNL combines transmitter and sensor in one recessed unit built for residential security systems.
Self-contained design
The transmitter and reed sensor come together in a single unit, so there is no separate sensor to match up.

Virtually disappears
Once installed, the recessed mount leaves very little visible on the door or window.
Wireless connection
It communicates wirelessly with 5800 Series receivers, so there is no sensor wiring to run.
Replaceable battery
A standard AAA Lithium battery powers the unit and is easy to replace when the time comes.
