Location
Precautions
Choosing the appropriate location for the Central Controller is
critical to the proper functioning of the system.
The Central Controller should be installed in the center of all the
transmitters, not necessarily in the middle of the house. It should
not be placed near any large metal objects, nor in the range of
appliances that generate RF interference.
Typical
appliances
that may be sources of RF interference are:
.
Personal computers and their modems.
.
Electronic Telephones, Telephone Controllers and
Accessories
.
Electronic Lamp Dimmers and Lighting Control Panels
.
Baby Monitors
In general, attention should be given to any device which could be
considered computer-like or digitally-controlled.
In the presence of these types of devices, use the following
precautions:
.
Keep at least 6 feet
between the source of the interference
and the Central Controller.
.
Do not group the power and telephone cords of the
interference source with the power cord/antenna for the
Central Controller.
.
Avoid using the same power outlet for the Central
Controller and interfering equipment.
In some cases, interference may be generated from outside of the
home. Installers should note nearby:
.
Airport
.
Television, public service, and radio towers
.
Large neighborhood antennas
.
Paper mills
AT&T should be notified in the event that the performance of the
system is being degraded by an outside source of RF interference.
