Product Overview
Plug n’ Go™ automatic configuration for quick installation and maximum energy efficiency Store 16 scene preset levels for each load Over-current protection: relay closes to prevent device damage in an over-current situation. Supports energy saving manual-on, partial-on and dimming control strategies
DESCRIPTION
LMRC-111-16M room controllers include one relay capable of switching a 16 amp load, a high-efficiency intelligent switching power supply and both Class 1 and Class 2 0-10 volt outputs for control of dimmable loads including compatible LED drivers or electronic ballasts. Room Controllers are the foundation of a Digital Lighting Management (DLM) system, and allow integration of occupancy sensors, daylighting controls and switches for energy-efficient control.
OPERATION
LMRC-111-16M room controllers operate on one 120 or 277 volt, feed and provide Class 2 power to sensors and switches via the DLM local network. Once powered up, Plug n’ Go automatically configures system components for the most energy- efficient operation. The room controllers then dim or switch lighting or motor loads in response to input from the communicating devices. When a dimming input is received, the relay switches on when the dimmed level rises above zero, and off when it reaches zero, to coordinate control of power and the 0-10 volt signal to the load. They also monitor the current draw of the total connected load. Each room controller stores up to 16 scene preset levels for each dimmed output. Room controllers include circuity to open their 0-10V signal on loss of power, so any separately powered ballast or driver connected to those 0-10V wires will go to full brightness.
FEATURES
- Push n’ Learn™ functionality for personalization without the need for tools or a PC
- Digital Lighting Management components plug together on a free-topology Cat 5e DLM local network eliminating wiring errors
- On/Off/Dim local override button for each load
- LED indicates status of load
- 0-10V signal opens on loss of LMRC power
- Instantaneous current and voltage measurement of total connected load
- 2 RJ45 ports; molded cable tie ring for strain relief
- Zero-crossing circuitry for reliability and increased product life
- UL 2043 plenum rated
- This product meets the materials restrictions of RoHS
- BAA/TAA-compliant models available
PLUG N’ GO AUTOMATIC CONFIGURATION
DLM room controllers manage Plug n‘ Go automatic system configuration, which establishes functionality based on the installed components. When room controllers are connected only to occupancy sensors, the system defaults to automatic on/off operation. If a wall switch is added to a system with one load, the load defaults to manual-on/automatic-off operation. At system startup, default dimming parameters are established including: levels for scene presets 1-4; fade times; and fade and ramp rates. Dimming and system parameters may be customized using Push n’ Learn.
APPLICATIONS
LMRC-111-16M room controllers are ideal for single zone on/off or dimming control applications including private offices, open offices, conference rooms and classrooms. Metering enables facility managers to track building power usage for lighting or other loads. A network bridge, either wireless or wired (LMBC-650 or LMBC-300), is required to expose DLM local network power measurement readings to a segment manager or LMBC-650 Border Router, so they can be shared with a BAS.
