Wireless Range; Type Of Construction - GE 45601 Manual

WIRELESS RANGE

This device complies with the Z-Wave standard of open-air, line of sight
transmission distances of 100 feet. Actual performance in a home
depends on the number of walls between the remote controller and the
destination device, the type of construction and the number of Z-Wave
enabled devices installed in the control network. Every Z-Wave enabled
device acts as a signal repeater and multiple devices result in more
possible transmission routes which helps eliminate "RF dead-spots".
Things to consider regarding RF range:
- Each wall or obstacle (i.e.: refrigerator, big screen TV, etc.) between the
remote and the destination device will reduce the maximum range of
100 feet by approximately 25-30%.
- Brick, tile or concrete walls block more of the RF signal than walls
made of wooden studs and plasterboard (drywall).
- Wall mounted Z-Wave devices installed in metal junction boxes will
suffer a significant loss of range (approximately 20%) since the metal
box blocks a large part of the RF signal.
