“Range Testing” Procedure:
1) Position the pair of intercom units in their respective locations (as
close to their final location as possible)
2) Power ON only a single pair of units (one Indoor and one Outdoor
Intercom units) to perform a “Range Test”. All other Intercom units
need to be turned OFF.
3) Ensure the “Outdoor” unit's antenna is min 8 feet above ground.
4) Flip the “TEST Switch” to ON position in the “RADIO SIGNAL
TEST” section of the board on “Outdoor” unit. The “QUALITY” LED
bar graph as well as the “LEVEL” and “HISTORY” LEDs will light
up. The unit will now automatically initiate communication with the
remote unit and provide the quality of the radio of the radio link
between them. Primarily focus on the “QUALITY” LED bar graph for
assessing the radio link (see figure 8).
5) If the “QUALITY” LED bar graph has more than 2 bars on,then the
link is GOOD (Skip next step)
6) If the LED bar has less than 2 bars, then do the following to improve
the range:
- Move the “Outdoor” intercom unit (or their antenna using
extensions) to different location
and observe the “QUALITY” LED bar graph again to see if the
range has improved.
- Move the “Indoor” Intercom unit (or their antenna using extensions)
to different location and observe the “QUALITY” LED bar graph
again to see if the range has improved.
Note: Repeat the steps above until the ideal location for antennas are
determined.
7) If the building walls are metal reinforced and the “Range Test”results
are poor, then the antenna of the “Indoor” Intercom unit may need to
be mounted near a window – using antenna extension cable(s). For
worst-case applications, the antenna may need to be mounted outside
of the building (on outer wall) (see Figure 9). Again, utilize the “Range
Test” feature to determine optimal position for antenna.
8) In applications where extreme range is required , high gain antenna my
be utilized (see Figure 10).
