WattStopper LMDM-101-W DLM Dimming Wall Switch, 1 paddle, w/IR, White

It connects to other DLM components with Cat 5e cable and RJ45 connectors rather than line voltage conductors landed at the switch. That is a plug-together low voltage run, so there is no switch leg to pull and no chance of miswiring a terminal. Plan your rough-in for a low voltage cable path from the switch box back to the DLM room controller, not a standard 120V switch loop.

The load has to be dimmable. The LMDM-101-W is a low voltage control station for dimmable loads, and the dimming itself happens in the DLM room controller or dimming module it plugs into, not at the paddle. Non-dimming loads switched from this device will only go on and off.

One. The LMDM-101-W is a single paddle device, so it raises, lowers, and switches one load. If the room needs separate control of two or more zones (say downlights and a whiteboard wall), you need a multiple paddle DLM dimming switch instead of this one.

Two things. A commissioning tech can configure the switch and the devices on its DLM segment wirelessly from a handheld IR configuration tool instead of pulling the device out of the box, and occupants can use an IR remote to raise or lower the controlled load from the room. That matters on jobs where you are setting levels in occupied space or in high ceilings.

Listed at 2.0 in width, 2.1 in height, and 4.5 in depth, with a total volume of 19.84 cu in and a weight of 0.3 lb. The depth figure is the one to check against your box: this is a low voltage station with an RJ45 connection on the back, so leave room behind it for the Cat 5e jack and cable bend.

There is an LED bar graph on the face that shows the relative light level of the controlled load. For a property manager or facility staff walking a space, that is the quick read on whether a zone is sitting at full output or has been dimmed down, without needing software.

Active Dim lets a user temporarily adjust the level of any selected load from the switch. It is a temporary override rather than a permanent change to the programmed level, which is what you want in a conference room or classroom where someone needs the lights down for a presentation and the space should return to its normal setting afterward.

The device is white. If you are standardizing an existing floor of white receptacles and switches, it will read consistently on the wall. Note that you are ordering the switch itself here, so plan a matching wall plate with the order.

The manufacturer part number is LMDM-101-W, a single paddle DLM dimming wall switch with IR in white. Country of origin is China. Distributors cross-referencing the line should note the trailing W is the white finish designator.
