18 Versus Information System
In multi-floor facilities, it is desirable to stagger locations. For example, to achieve better
coverage, do not place the sensor on the third floor directly above the sensor on the second floor.
If using the VIS to track assets with the Asset Tag (VER-1830) or RF/PAS Tag (VER-1875), the
required placement of these tags may affect the number of RF sensors needed to achieve effective
coverage. If the tags must be placed near a metal surface or are offset from a metal surface by a
bracket, the RF signal emitted may be reduced in strength due to absorption by the metal. In these
cases, more RF sensors may be needed to compensate for the lack of RF signal. If you plan to
mount Asset or PAS tags near a metal surface, contact Versus Technology for more information
on appropriate RF coverage.
Important: Each Collector should have no more than four RF sensors connected to it.
3.3.4 Mapping the Sensor Locations on the Floorplan
The sensor locations should be mapped out on a floorplan diagram of the facility. These are the
locations where the sensor cable will be run. We suggest using a numbering scheme such as C1-1,
C1-2, C1-3, C2-1, C2-2, C2-3 etc., where “C1” represents Collector 1 and “C2” represents
Collector 2. Up to 24 sensors can be connected to one collector, although we recommend 20-22 to
allow for future expansion. The wires should be labeled at both ends with these numbers as well.
The facility must provide a list with the names of the rooms. The room names will be used for
configuring software. Once the sensors have been mapped with identification numbers, and the
facility has provided a list of names of the rooms, complete the Punch-down Block Organization
Chart (located in Section 6.5) with the number and the room name. You should also add the
receiver numbers, which will be used for configuring the software. Number the receivers with
incrementing numbers (1, 2, 3…). If there is more than one IR sensor in a particular area, they
may be assigned the same receiver number if you choose, but it is not necessary. Under normal
circumstances, do not assign an RF sensor and an IR sensor the same receiver number unless you
are using the PAS system (contact Versus for more information). When assigning RF sensors,
Versus recommends adding an RF designation to the description. See the following example chart.
