“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).
