Battery InstallatIon
Carefully separate the top of the enclosure from the bottom. Locate the battery holder on the circuit
board. Take note of the polarity markings identifying the positive and negative ends of the batteries.
Install the batteries. Re-attach the top and cover.
Power suPPly wIrIng (router Mode)
When using your wireless sensor in Router mode, you must use an external power supply (Sensaphone
Part #XFR-0041). This is required because router mode uses more power than can be supplied by
batteries alone for an extended period of time. You can also use a power supply when the sensor is
configured as an End Point, which will greatly extend the life of the batteries and minimize the need to
change them.
To connect the power supply, remove the sensor cover and locate the screw terminals labeled “5V DC”.
connect the positive wire from the power supply to the “+” terminal. Plug the power supply into an
appropriate outlet.

MountIng
The temperature sensor can be mounted directly on a flat surface.
Consideration should be given as to whether or not an electrical outlet will
be required if using the optional power supply. Mount the sensor as high as
possible to provide for optimal Wireless transmission. When installed within
a building where the Wireless signal must travel through several obstructions,
the sensor should be located within 250’ of the WSG30 or within 300’ of a
sensor/router.
Use a pencil to mark the hole locations at the top and bottom of the housing.
Install the drywall anchors (if necessary) to the wall. Attach the housing to
the wall using #6 tapping screws.
