“Threshold”

Set the threshold such that the Receiver can detect a Tag from about a 25’ radius within the protected
perimeter. This detection area is highly dependent on the layout of the floor which in turn influences the
placement of the Receivers on that floor. Generally, ensure that the whole floor has adequate coverage, and
eliminate any “null” areas from which a Tag removal cannot be detected.
Figure 18 – HALO Receiver
5.8.1. Threshold Switch
The Threshold switch may be adjusted to increase or reduce the sensitivity of the Receiver and therefore
the range of detection of the Tag.
It is also used to remove some of the background noise as well as reduce interference from tags if the
controller is having trouble detecting tags. The result in the adjustment raises the RF field strength
threshold received from the tags in order to trigger the CPM into alarm (ie. from 25uV to 50uV) and
reduces the detection field range.
‘0’ = MAX sensitivity & ‘F’ = MIN sensitivity. The default setting is “2”.
