Transmitter Installation Location Guidelines
When planning the system installation, Primex Wireless recommends taking into consideration the below transmitter
installation guidelines. Location is extremely important to ensure the best operation of your system.
All Transmitter Models
l
In multi-story buildings, installation the transmitter on the top floor will often significantly improve coverage to
the lower floors due to the “umbrella” pattern of transmission.
l
Transmitter should be located a minimum of two to three feet above the floor.
External Antenna Models
l
Locate transmitter within 5 feet (1.5 m) from a 240 VAC electrical outlet.
l
In the event that metal objects extend above the level of the ground plane, the radiation pattern will be
distorted. Radiation through metal objects will be lower than from other directions.
l
The antenna cannot be placed on or directly adjacent to walls or metal structures.
l
Antenna is required to be a minimum of 15' (4.57 m) clear from the radius of other antennas.
l
Locate transmitter within 100' (30.48 m) of antenna. The maximum cable length allowed between the antenna
and transmitter is 100' (30.48 m).
l
The transmitted signal from the antenna radiates in a circular and “umbrella” pattern; therefore a central location
for the transmitter where the antenna is at maximum allowable height is recommended to ensure best possible
coverage.
NOTE:
Prior to installation and to assure optimum performance of the system, it is recommended a Primex Wireless
Application Engineer performs a site survey. The site survey includes an analysis and recommendation of the
installation location of the system components and ground plan omnidirectional antenna.
GPS Receiver Installation Location Guidelines
Determine a suitable location for the GPS receiver unit. Location is extremely important to ensure the best operation of the
system. You must consider the following:
l
GPS receiver unit requires a "clear view of the sky" to receive a GPS signal 24 hours a day.
l
Typical mounting locations of the GPS receiver unit include the inside of a window (not a Low-E glass window),
to an exterior pole or on a rooftop.
l
GPS receiver unit should be kept away from large metal objects.
l
GPS receiver unit and cable are mounted above any potential standing water, snow depth, leaves or other
obstructions and it protected from weather.
