KX4 4 inch In-Wall Touchpanel Keypad w/ Control Processor

Now Shipping

Ideal for single room commercial applications such as meeting rooms, classrooms, and lecture halls, the KX4 combines an in-wall touchpanel and hard button input with a built-in control processor. The result is an enhanced automation solution that combines control simplicity with power in a single cost-effective unit. For front panel control, the KX4 boasts a 4” high-resolution capacitive touch display with five configurable hard-buttons that can be customized with RTI’s Laser Shark engraving.


The built-in control processor features advanced capabilities, including support for two-way drivers, RTiPanel App and expansion configurations. Back panel connections enable direct control of devices via IR, IP and two RS-232, six voltage sense ports with sense-event capabilities, and four relays for control via contact closure.

Integration Designer software only available to authorized RTI dealers.

Included in the box:
KX4, bezel (white), RJ45 to DB9 serial adaptor (2), mounting wings (2), drywall template, screws (4)

KX4 Features

Blend your flush-mount touchpanel into the wall and make it a central point for controlling your home or business.

Hard Buttons 
Five Hard Buttons provide quick access to often used control functions such as lights, music, audio/video source selection without the need to navigate through the graphical interface on your touchpanel.

Convenient and reliable control with status feedback from controlled devices such as on/off or arm/disarm status, dimming value of lights, playlists, available stations.

Two (2) control ports for 3-wire connection with the capability of polling status feedback from controlled devices or systems.

Four (4) built-in low voltage dry contacts that provide contact closure or switching control for loads up to 2A/30VDC (external power supply required).

One (1) control port for 2-wire connection to infrared emitters, blasters and repeaters.

Sense Input
Six (6) inputs that sense contact closure from switches, windows or doors or voltage state from a voltage sensor to trigger a programmed control command or macro.

Standard 10/100 BaseT wired network connection for bidirectional control communication with RTI remotes, control accessories and devices that are controlled over IP network.

Power your touchpanel through a PoE network switch or PoE injector. No extra power supply required.

Standard wireless Zigbee connection for bidirectional control communication with RTI remotes.

Astronomical Clock
Built-in clock that syncs through an internet connection allows to schedule time-based events to automate all aspects of the installed environment, including climate, lighting, music, and much more.

Laser Shark
Customize the button labels with text or graphics.
