Product Overview

The CLC-1DIMFLV2EX-24V is a two-channel 0-10 Volt dimmer capable of controlling two independent, 24 Volt DC lighting loads in an EMerge Alliance® application. Perfect for use with the Armstrong® DC FlexZone™ ceiling grid,[1] this module’s ultra-slim design allows it to be installed in the ceiling, either on or near the lighting fixture. Powered by infiNET EX® technology, the CLC device communicates wirelessly with the Crestron® control system, making it perfect for both new and retrofit applications. Additionally, the dimmer includes inputs for a photocell, occupancy sensor, and standard toggle or momentary switch.

EMerge Alliance Registered

The CLC-1DIMFLV2EX-24V is 100% EMerge compatible, designed to flawlessly work within a 24 Volts DC room-level power distribution system. The EMerge Alliance is a not-for-profit open industry association leading the rapid adoption of safe DC power distribution in commercial buildings through the development of EMerge Alliance standards.[2] Crestron is a proud member and supporter of the Alliance.

Onboard Sensor Inputs

Each module comes equipped with onboard inputs for use with photocells and occupancy sensors. This unique feature not only reduces wiring costs, it also eliminates the need for extra hardware

Out-of-the-box Control via Standard Switch

The CLC-1DIMFLV2EX-24V uses either a momentary or a maintained switch to provide a closure, such as a standard lighting switch. A standard lighting switch, the kind carried in any hardware store, is a cost-effective solution for basic on and off functions. A momentary, pushbutton-type switch can be used when the application requires dimming the load. The momentary switch can be set up so that tapping the button turns the connected load on and off, while pressing and holding the button dims the load up or down.

Complete Crestron Control

Because it's connected to the Crestron system, the CLC-1DIMFLV2EX-24V can also be controlled from any keypad, touch panel, remote, or mobile device. Tie in occupancy sensors and photocells together with Crestron Fusion EM® software for a complete solution to effectively manage energy.

Simple Setup

Setup is simple, especially when using a connected maintained or a momentary switch. A specific series of button presses initiates the wireless device's acquire mode, so there's no need to climb a ladder to join the device to the infiNET EX network.

infiNET EX

Ultra-reliable infiNET EX wireless technology provides steadfast two-way RF communications throughout a residential or commercial structure without the need for physical control wiring. Employing a 2.4 GHz mesh network topology, each infiNET EX device functions as an expander, passing command signals through to every other infiNET EX device within range (approximately 150 feet or 46 meters indoors), ensuring that every command reaches its intended destination without disruption.[3]

The CLC-1DIMFLV2EX-24V communicates with a Crestron® control system via an infiNET EX Wireless Gateway (model CEN-RFGW-EX, DIN-AP3MEX, or MC3[4]). Up to 100 infiNET EX devices may coexist on a single wireless network, and every device that is added to the network effectively increases the range and stability of the entire network by providing multiple redundant signal paths.[3] Built-in Dynamic Frequency Allocation continuously monitors RF conditions, automatically selecting the clearest channel to prevent interference from neighboring networks, cordless phones, and microwaves.

More information on integrating the CLC-1DIMFLV2EX-24V in a 24VDC system can be found in the Commercial Lighting Design Guide: EMerge Alliance® Registered Products, 24 Volt DC Edition (Doc. 4558).
