WiRELESS SENSoRS
The WSG30 allows you to configure up to 30 wireless sensors. Sensors are available to monitor a variety
of environmental conditions - see Appendix B for a complete list. A successful installation will require
some planning to make sure everything will work smoothly. The WSG30 and sensors utilize mesh
networking technology to ensure reliable wireless communications, but this requires that you follow a
few rules during the setup process.
#1: Upon initial setup, you must configure one sensor at time. DO NOT power-up all of your sensors
and then configure the system. This will not work.
#2: If you will have more than 7 sensors you must configure one or more as a router. See the description
below regarding Routers and End Points. Determine how many routers you will need and configure them
first.
RoutERs and End-poInts
WSG30 wireless sensors can be configured as either routers or end-points. A sensor configured as a
router can be used to provide redundant wireless paths from your sensors back to the WSG30. This is
useful if the distance from your sensors to your WSG30 is too far for direct communication. Note that
routers must be powered by an external power adapter. In this case, the sensor’s AA batteries will serve
as backup in the event of a power failure. Note that routers are required once you exceed 7 end-points.
You can have as many routers as you like.
A sensor configured as an end-point will simply send its readings back to the WSG30, or a nearby
router, and then go into a very low power mode. End-points can be battery-powered and have the
capability of operating on batteries for several years. If the end-point is too far from the WSG30 for
direct communication, a router must be installed to bridge the gap. See the examples below:
Example 1 - Up to Seven Sensors within 300’ of the WSG30
No routers are required in this case. Each sensor is within range for direct communication with the
WSG30 and the number of end -point sensors did not exceed 7.
