Honeywell DC311N Wireless Portable Door Chime Kit 4 Tunes in White

The DC311FN is a wireless door and window contact sensor from Honeywell Home (Honeywell Home), designed to provide discreet and reliable monitoring as part of a modern intruder alarm system. Built for applications where a compact or narrow-fit solution is required, it offers secure protection of entry points while maintaining a low-profile appearance that blends neatly into residential or commercial environments.

Engineered for dependable performance, the DC311FN uses wireless RF communication to transmit real-time status updates to a compatible alarm control panel. When a door or window is opened or closed, the sensor immediately sends a signal, enabling the system to respond quickly with alerts or notifications. This helps improve overall security coverage and ensures continuous monitoring of key access points without the need for wired connections.

Its slim, discreet design makes it suitable for installations where aesthetics and space constraints are important. The unit is typically battery-powered, allowing flexible placement on doors or windows without complex installation work. It integrates seamlessly into Honeywell Home alarm ecosystems, making it a practical choice for both new installations and system expansions.
