If the room has windows that allow a large amount of sunlight to enter the room, place the sensor in a
position where the sunlight does not reflect directly into it from objects in the room. Sunlight can
decrease sensor range and field of view if allowed to enter the sensor. Window tint films that block
infrared (heat) energy greatly reduce this effect.
3.2.3 RF Sensor Location Planning
Planning the location of RF sensors depends upon the facility. In most cases, for complete coverage,
they can be placed approximately 100’ apart, because they have a sensitivity range radius of 50’.
However, because concrete and steel structures absorb the RF signal, and other materials affect the
strength of RF signals, testing is necessary to determine the best placement of RF sensors. In multi-
floor facilities, it is desirable to stagger locations, i.e. do not place the one on the third floor directly
above the one on the second floor, for better coverage.
3.2.4 Mapping the Sensor Locations on the Floor Plan
The sensor locations should be mapped out on a floor plan 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 should provide you 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 with
the number and the room name. You can 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 sensor in a particular area, they will have the same receiver number. See the example chart
below.
