CHANNEL SELECTION
The Sensaphone 2800 and associated sensors must be set to operate
on the same wireless channel. There are four possible channels.
If you will be installing more than one 2800 unit in the same area
you must configure each system on its own channel. By default the
2800 and sensors are set to channel one. To change the channel on
the sensor, remove the cover using the hex key. Turn the hex screws
clockwise until the cover easily slides off. Next, locate the jumpers
on the circuit board as shown in the figure below. Remove all power
from the sensor by taking out the alkaline batteries and unplugging
the power supply (if used). The table shows how to configure the
jumpers for a particular channel.

will notify you when the batteries are starting to get low. If you
prefer you can install the optional plug-in power supply and use the
batteries as a back-up in the event of an AC power failure. Install
the 3 AAA batteries as shown below:
