Stock spans the full DLM chain: room controllers (LMRC-101, LMRC-211, LMRC-212, LMRC-213), the LMZC-301 zone controller, LMDC-100 and LMPC-100 ceiling occupancy sensors, DW-311 dual-tech wall-switch sensors, LMLS-400 and LMLS-500 daylight photosensors, LMPL-101 and LMPL-201 plug-load controllers, the LMBC-300 wired network bridge, and LMRJ pre-terminated Cat 5e cable from 6 inches to 100 feet. Nationwide shipping, contractor pricing on request.

Rock stocks the LMRC-101 (single relay, on/off), the LMRC-211 (single relay with 0-10V dimming), the LMRC-212 (two relays with 0-10V dimming) and the LMRC-213 (three relays, 0-10V dimming, 20A), plus the LMZC-301 zone controller and the LMBC-300 wired network bridge that connects DLM rooms to an Ethernet LAN.

Rock stocks the LMDC-100 dual-technology ceiling sensor, the LMPC-100 PIR ceiling sensor including the LMPC-100-1 high-density lens and LMPC-100-5 high-bay lens versions, and the DW-311 dual-tech 0-10V wall-switch occupancy sensor rated 120/277V, available in black, grey, ivory and further finishes.

Rock stocks the LMLS-400 closed-loop single-zone photosensor and the LMLS-500 open-loop multi-zone photosensor, each also available in an extended or long-neck version (LMLS-400-L and LMLS-500-L), plus the LMLS-MB1 J-box and LMLS-MB2 wall mounting brackets. A closed-loop sensor reads the light level in the space it controls; an open-loop sensor reads incoming daylight and drives multiple zones.

DLM (Digital Lighting Management) is Legrand Wattstopper's plug-and-play networked lighting-control system for commercial spaces. Devices in a room connect to a room controller with pre-terminated Cat 5e cable, and the controller switches and dims the load. Rock Lighting stocks DLM room controllers, sensors, and accessories.

Both are DLM room controllers with 0-10V dimming. The LMRC-211 switches a single relay load; the LMRC-212 switches two, letting one controller handle two separately-switched zones in the same room.

DLM devices connect with pre-terminated LMRJ RJ45 Cat 5e cables in a free-topology layout, so there is no point-to-point control wiring to lay out. Rock stocks LMRJ lengths from 6 inches to 100 feet, including 3 foot and 10 foot runs, in non-plenum green.

Yes. Wattstopper DLM is a networked lighting-control platform that integrates with building systems via BACnet, and Legrand offers DLM-compatible demand-response components for automated demand response programs. Rock Lighting & Electric stocks DLM room controllers, sensors, and network components. Send your device schedule for a quote.

Yes. Rock stocks Wattstopper occupancy and vacancy sensors and controls commonly used to meet California Title 24 requirements, including the LMDC-100 ceiling sensor and DW-311 wall-switch sensor, paired with LMRC room controllers for the automatic shutoff and multilevel dimming the code calls for.
