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

The ultimate single-room control solution combining touchpanel interface and professional control processor in one cost-effective unit.

Perfect for commercial applications such as conference rooms, classrooms, and lecture halls, the KX4 delivers enhanced automation with unmatched simplicity. This innovative in-wall touchpanel control solution combines a 4" high-resolution capacitive touchscreen with five configurable buttons, plus an integrated control processor—eliminating the need for separate components while delivering professional-grade custom control programming capabilities.

The vibrant touchscreen provides intuitive system control while the five back-lit buttons offer instant access to frequently used functions. Each button can be personalized with RTI Laser Shark engraving for clear identification and professional appearance. This thoughtful design ensures reliable operation in demanding commercial environments where ease-of-use is paramount.

The built-in professional control processor features advanced capabilities including support for two-way drivers, RTiPanel App connectivity, and seamless expansion configurations. Comprehensive back-panel connections enable direct device control via IR, IP, and dual RS-232 ports. Six voltage sense ports with sense-event capabilities plus four relays provide extensive control via contact closure for lighting control integration, motorized screens, and other commercial automation systems.

Integration Designer software is available exclusively to authorized RTI dealers.

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

Details

In-Wall
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.

2-Way
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.

RS-232
Two (2) control ports for 3-wire connection with the capability of polling status feedback from controlled devices or systems.

Relay
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).

Infrared
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.

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

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

Zigbee
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.
