I would like to use the ccupancy sensors to track the sole-occupier movements throughout a 2-strorey maisonette. If this is possible, I would then like to control lighting, HVAC, audio and video based on the presence of the occupier.

Asked by: Anonymous
The Wattstopper DLM system natively controls lighting and uses BACnet communication to integrate with a Building management system to control HVAC and AV. Please contact your local Wattstopper Rep to help you design a system that will work with your specific needs.

Can the occupancy sensors be daisy chained if the light fixtures are working off the same switch, but the light fixtures have there own individual occupancy sensor?

Asked by: Baron
Yes, they can be daisy chained - the load binding is determined by programming, not by the cat5 wiring.

Does LMDC 100 motion sensor work through glass.?

Asked by: Anil Pandya, PE
Anil, Ultrasonic sound waves do not penetrate solid objects well and the PIR sensor cannot "see" through glass because this signature cannot travel through it. Some of this depends on the type of glass used in the window like thinner glass, we have cases where the sensitivity is lowered and it works and some where the sensor needs to be relocated.
