BATTERY INSTALLATION
The Wireless Indoor Dry Contact Sensor can operate for up to 3
years on a set of AAA alkaline batteries. The Sensaphone 2800
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:

If you will be installing the optional 5V power supply, connect the
wire marked “+” to the “+” screw terminal and connect the wire
marked “-” to the “-” terminal on the PWR terminal strip. Next,
plug-in the adapter.
After you have configured the channel, installed the AAA batteries
and/or connected the AC 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.
