Wireless Information
This device has an open-air line-of-sight transmission distance of 25m 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 20m by up to 20 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 20 to 30%.
Maintenance
1. Do not expose your unit to dust, strong sunlight, humidity, high temperatures or
mechanical shocks.
