BATTERY INSTALLATION
The sensor uses the wall plug-in power supply to both sense the
presence of power and also to power the device, so that it can
communicate with the 2800. The alkaline batteries are used to
power the device when main AC power fails. As a result, the
batteries will likely last for several years, however they should still
be replaced after a few years to insure that they will be able to
power the device when needed.
Wire the power supply to the sensor before you plug it in. Connect
the wire marked “+” to the “+” screw terminal and connect the wire
marked “-” to the “-” terminal on the PWR terminal strip. Plug the
power supply into the outlet you want to monitor. Next, install the
AAA alkaline batteries. See figure below:

After you have configured the channel, installed the AAA batteries
and connected the power supply, replace the cover and secure
it by turning the two hex screws on the bottom of the cover
counterclockwise.
BATTERY INFORMATION
The projected battery life is dependent upon many factors including:
rated capacity of battery, state of charge, temperature, and sensor
distance from the 2800 (or repeater). The farther a sensor is from its
receiver the more power it will require to transmit its signal, thus
reducing battery life. Higher temperatures will also decrease battery
life. Always use high quality alkaline batteries in Sensaphone 2800
series wireless sensors. Remove the batteries from the sensor if you
will be taking it out of service for a period of time.
