Temperature Guard Description
The Temperature Guard monitors temperature and power wherever
it is located, and dials the programmed emergency phone numbers
if the temperature goes out of programmed limits or if the power
goes out for more than five minutes.
Programming Overview
Programming the Temperature Guard is accomplished over the
phone and only has to be done once, unless it is necessary to make
a change. Before programming, do the following:
1 Connect a phone line, plug in the power pack to an outlet, and
connect the power jack.
Use of a phone and power line
surge suppressor is strongly recommended.
Turn the unit
on by moving the power switch from the position labeled 0 to
the position labeled 1.
2
From another phone line dial the number where the Tempera-
ture Guard is located. The Temperature Guard will pick up after
the first ring.

The Temperature Guard prompts for the 4-digit PIN number.
Enter the factory default PIN number, 0000
