REPLACING THE TEMPERATURE ELEMENT
The internal temperature element (2.8K thermistor) can be replaced
with an external probe for monitoring temperature within a
refrigerator/freezer or other harsh environment. Sensaphone part
# FGD-0101 is a weatherproof temperature probe that is ideally
suited for this purpose. Before installing the probe you may want
to disable the corresponding input channel on the 2800 to prevent
an alarm from occurring while changing the probe. To install
the probe, remove the sensor cover and loosen the sensor screw
terminals and remove the thermistor. Next, connect the wires from
the weatherproof probe to the terminal strip. There is no polarity
for temperature sensors. Reattach the sensor cover and re-enable the
input on the 2800.
