WIRELESS INFORMATION
Wireless range:
This device has an open-air line-of-sight transmission distance of 100 
feet which complies with the Z-Wave standards. Performance can vary 
depending on the amount of objects in between Z-Wave devices such 
as walls and furniture. Every Z-Wave device set up in your network 
will act as a signal repeater allowing devices to talk to each other and 
find alternate routes in the case of a reception dead spot. 
Radio frequency limitations: 
1. Each wall or object (i.e.: refrigerator, bookshelf, large TV, etc) can 
reduce the maximum range of 65 feet by up to 25 to 30%.
2. Plasterboard and wooden walls block less of the radio signal then
concrete, brick or tile walls which will have more of an effect on 
signal strength. 
3. Wall mounted Z-Wave devices will also suffer a loss of range if
they are housed in metal junction boxes which could also reduce 
the range by up to 25 to 30%.
