WattStopper LMDC-100 – Frequently Asked Questions

1) Does the WattStopper LMDC-100 ceiling occupancy sensor need a separate power pack or relay to switch the lights?
The LMDC-100 is a DLM network device, not a standalone switching sensor. It connects by Cat 5e cable onto the DLM local network and reports occupancy to the network; the actual load switching happens at the DLM room controller. Plan the job with a room controller and Cat 5e runs from the sensor location, not line-voltage wiring at the sensor itself.
2) Will a dual technology sensor work in a room where a PIR-only sensor keeps dropping the lights on people?
That is the case dual tech is built for. The LMDC-100 runs passive infrared and 40KHz ultrasonic together, so someone seated still at a desk or behind a partition, out of the PIR line of sight, still registers on the ultrasonic side. Detection Signature Processing filters the signals so airflow or HVAC motion does not trigger a false on. Private offices, conference rooms, and restrooms with stalls are where this pays off over PIR alone.
3) Can the LMDC-100 sensor time delay and sensitivity be changed after it is installed without a laptop?
Yes, two ways. Push n Learn lets you adjust settings at the device with no PC and no special tool, and the built-in infrared transceiver accepts wireless configuration from a remote. Useful on occupied floors where you are tuning time delays after the tenant complains rather than pulling the sensor back down.
4) How much ceiling space does the WattStopper LMDC-100 sensor take up and how far does it drop below the ceiling?
It is a compact ceiling puck, 4.5 by 4.0 by 2.2 inches and 0.42 lb. That 2.2 inch figure is the height dimension, so it is a light enough device that it is not a structural concern on a tile or hard ceiling. Finish is white.
5) Does the LMDC-100 need to be commissioned or programmed at startup?
Not to get basic operation. Plug n Go automatically configures the device when it comes up on the DLM network, so the room works out of the box on a plug-and-play Cat 5e connection. You only go into Push n Learn or the IR remote when you want to move off the default behavior.
6) Will ultrasonic sensing false trigger from the HVAC diffuser or nearby radio equipment?
The LMDC-100 has Detection Signature Processing specifically to strip false triggers, plus immunity to RFI and EMI. The ultrasonic side runs a patented 40KHz diffusion pattern that spreads coverage wide rather than beaming it, which is what lets it cover an irregular room from one ceiling point alongside the 360 degree PIR pattern.
7) What is the exact part number to order for the WattStopper DLM dual tech ceiling sensor?
Order it as WattStopper LMDC-100. That is the V4 dual technology ceiling mount occupancy sensor in white, and it is a single configuration, so there is no finish or coverage suffix to pick on the order.
