3.0 Choosing a Location for the RTU and Antenna
The location you choose for installing your AlarmAgent TM RTU is important if the antenna is mounted
directly on top of the RTU. This is because the antenna location has a lot to do with the signal strength
of the wireless connection to the local cellular tower.
If the antenna is to be located separately from the RTU, then the mounting location of the RTU is not as
critical.
To select an optimum location for either the RTU with top-
mounted antenna or for a separately located antenna, use the
bar-graph LED signal strength indicator built into the RTU.
To view the signal strength indication, turn on the RTU.
If input power has not yet been connected, you can still view
the bar graph which will flash along with all other LEDs).
The stronger the signal strength is, the more segments that will
be illuminated. At least four segments of the bar graph should
be lit, allowing for momentary variances. Allow a few seconds
for the indication to adjust to any new antenna positioning.
Note: See Appendix A for advanced antenna information
4.0 Mounting the RTU
With the mounting location for the RTU determined, use the enclosed Mounting Template diagram
(Appendix G) to establish mounting-hole locations. This diagram includes hole locations for RTUs with
three different enclosure options:
1. Standard Indoor
2. NEMA 4X
Note: If you are installing the RTU
inside a metal enclosure, it will be
necessary to install an antenna at a
separate location outside the metal
enclosure.
If the RTU is being installed in a control
panel at a location other than the final
destination, issues of antenna placement
and network testing will need to be dealt
with separately at the time of final
installation at the ultimate RTU site.
