Omega Vehicle Security Wireless Sensor System zSeries - Manual (Page 64)

PART 5
ENVIRONMENT / OPERATING CONDITIONS
End Device/Coordinator are designed to be fixed mounted and operated in a clean and
dry environment. Care should be taken to prevent the components of your wireless
system from being exposed to moisture, toxic chemicals, extreme cold or hot
temperature that are outside the specification listed in this manual.
The following is a list of basic good practice you should apply when operating this
Wireless System.
1. Do not operate the wireless device in flammable or explosive environments.
2. Do not use the wireless device in medical, nuclear or any other critical
application where failure can cause damage or harm.
3. Always operate the wireless device within the recommended environmental limits
specified in this manual.
4. Do not operate your wireless device with a battery or AC adapter other than
what’s supplied or specified in this manual or on the battery compartment label.
5. Keep each wireless device at least 8 inches (20 cm) from other radio
transmitters, antennas, and people.
6. The FCC approval for this device specifies the specific antenna supplied with this
device.
5.1 General Deployment Guidelines
1. Position Coordinator in a central location. When multiple End Devices are in
operation, position your Coordinator in a central space if possible in equal
distance to each End Device.
2. Test your system before permanent mounting. Try to move the devices to
different location around and mounting angles to determine what installation
achieves the best signal strength before permanently mounting the End Device.
3. Move your system components higher off the floor and away from exterior walls.
The closer the End Device/Coordinator are, the greater the interference and lose
of signal strength will be.
4. Maintain a line-of-sight between antennas and keep Fresnel zone free of
obstruction. See Figure 5.2.
5. Maintain a constant ambient temperature environment. Exposing your system
components to extreme cold or hot temperatures, or sudden changes in ambient
conditions will have an effect on the performance of your system.
6. As a general rule in buildings, head height or above is preferred. On the other
hand, End Device stays close to the floor may have their range reduced by 50%
to 90%.
