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.
NOTE: If the sensor has only batteries installed and it is not
configured for communication with the 2800, it will consume
maximum power trying to establish communication and result
in premature battery failure.
COMMUNICATING WITH THE 2800
The sensor will communicate with the Sensaphone 2800 every 20
seconds. As a result, alarm detection at the 2800 may be delayed.
See chapter 4 for information on setting the wireless channel in the
2800 and for adding a sensor.
