•
Wall blockage occurs when a large reflective object obscures the view of the target
area. The reflective abject may be within the wall itself or in close proximity to the
wall. The RANGE-R2D sensor alerts the operator if such a condition exists.
•
Since it is possible that the transmit signal is being blocked and not reaching
potential targets, target detection is not possible when blockage is detected.
•
While operating in Scan Mode and with blockage detected, the word “Blocked”
will be displayed. If this occurs, the operator should move to a different spot on
the wall and try again.
•
In some situations, a blockage alert indication may not occur even though the
signal is blocked. One such blockage could manifest if the system is held up directly
against a metal door or wall.
•
In this situation, the transmit signal is completely blocked and little to no energy
reaches the receive antenna. Because the power threshold for a blockage signal
will not be exceeded, no alert is generated. Another scenario occurs when the wall
material is highly absorptive. Here, signal returns from the obscuring object are
greatly reduced by losses in the wall. The power threshold for a blockage signal is
not exceeded and no alert is generated.
