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.
2From another phone line dial the number where the Tempera-
ture Guard is located. The Temperature Guard will pick up after
the first ring.
3The Temperature Guard prompts for the 4-digit PIN number.
Enter the factory default PIN number, 0000.

8 You will be automatically returned to the Program Menu
Enable / Disable the Temperature and Power Status Message
From the factory, the monitor prompts the caller for the PIN num-
ber before allowing the caller to hear the current temperature and
power status. This prevents anyone from learning that the home is
unoccupied. To have the monitor report the temperature and
9

1010
power without entering the PIN, perform the steps below.
1 From the Program Menu, press 9
2 You will hear the current setting. Default is “off”, the status mes-
sage will not be broadcast before the PIN has been entered.
3 You will hear “Press one to change.”
4 Press 1 if you wish to activate the Status Message before PIN
5 You will hear the new setting. “On” will cause the monitor to
broadcast the Status Message Before PIN Entry.
6 You will be automatically returned to the Program Menu
Fahrenheit or Celsius Temperature Readings
The monitor can report the temperature in Fahrenheit (default) or Cel-
sius. To switch to Celsius, perform the steps below.
1 From the Program Menu, press *
2 You will hear the current setting. Default is “C off”, the tempera-
ture is being output in degrees Fahrenheit.
3 You will hear “Press one to change.”
4 Press 1 if you wish to change the Temperature Readout Mode and
have the temperature output in Celsius.
5 You will hear the new setting, “C on”.
6 You will be automatically returned to the Program Menu
Where to Locate the Monitor
The monitor measures temperature and power wherever it is located.
If the monitor is being used to protect against freezing temperatures,
locate it in an area where the temperature will drop the fastest, if the
heating system fails, such as a room with a northern exposure or nu-
merous windows.
If the monitor is being used to protect equipment against overheating
in case air conditioning fails, locate the monitor close to the equipment
and close to the ceiling where heat will build up quickest.
Once the location is chosen, connect the phone line and power. Turn
on the power switch (the light next to the phone line will start blinking
at a rate proportional to the temperature). Follow the instructions in
the Programming section.
What happens when the Monitor calls?
1 The monitor will play the personal identification message, followed
by the cause of the alarm.
2 The monitor will ask for the PIN number
3 Once the PIN number has been entered, the monitor will not call
again because the current alarm condition has been acknowl-

edged.
4 If the PIN is not entered, the Monitor will repeat the sequence
one time.
What happens if I call the Monitor while an alarm condi-
tion exists?
1 If the Status Message Before PIN Entry is Active, you will hear
either “Warning, the temperature is XX” or “Warning, the
power is out”, otherwise you will just hear “Enter your PIN num-
ber”
2 If the PIN number is entered, the monitor will stop making
emergency phone calls.
3 If the PIN number is not entered, the monitor continues dialing
the emergency phone numbers.
What happens when the Temperature Guard calls a
pager?
The Temperature Guard will print the Local Identification number
The Temperature Guard will print the temperature.
The Temperature Guard will then print the power status. 1 for
power on and 0 for power off.
Example, if you saw 12340751 on the pager's display, 1234 is the
user ID, 075 indicates a temperature of 75 degrees, and the last 1
indicates power is on.
The Temperature Guard will continue to call the pager and any
other programmed phone numbers until either:
•The alarm condition goes away OR
•The Temperature Guard is called and the PIN number is en-
tered
•The Temperature Guard calls a voice number and contacts a
person who enters the PIN number.
Reading the temperature from the blinking light
1 Wait for the light located next to the phone line to be on for ap-
proximately 2 seconds.
2 Count the number of blinks until the light is off for 1 second.
This number of blinks is the 10’s digit of the temperature.
3 Now count the number of blinks until the light is again off for 1
second. This is the 1’s digit of the temperature.
4 The temperature is calculated by: (multiply the number of
blinks counted in step 2 by ten and then add the number of
1111

blinks counted in step 3. For example, if the number of blinks
counted in step 2 is seven and the number of blinks counted in
step 3 is two, then the temperature is (7 x 10) + 2 = 72 degrees.
Connecting the Monitor to a Phone Line which has a fax or
answering machine connected to it
Program the monitor to answer after one more ring than the other de-
vice on the line. This allows the other device to always answer first.
To call and access the monitor
1 Dial the phone number
2 Hang up one ring before the other device answers.
3 Wait no longer than 30 seconds, then dial the number again.
4 The monitor will answer.
Example: An answering or fax machine on the same line as the moni-
tor and is set to answer after 4 rings.
Program the monitor to answer after 5 rings.
To access the monitor, dial the number, let it ring three times, then
hang up. Wait 30 seconds and call again. After two rings, the monitor
will answer.
Verifying that the Monitor will call all the phone numbers
To verify that the monitor will call all of the programmed phone num-
bers, perform the following test.
1 Use another phone line and call the monitor.
2 When asked to enter the pin number, enter “#999“ (including the
“pound” sign).
3Hang up after the monitor says “Goodbye”
4 The monitor will call all of the programmed telephone numbers.
Do not enter the PIN during this process or the unit will stop calling
out.
You can listen in to verify communication by waiting 10 seconds
after hearing “Goodbye” and listening in on a phone on the same
line.
If you have DSL at your home, then you must use a DSL fil-
ter on the phone line going to the monitor.
If the Monitor does not answer the phone
Verify that the phone line is working. Connect a phone to the line in-
tended for the monitor. Verify that there is a dial tone. Check that the
phone line is plugged in securely. Verify that the monitor is powered
12

up and the status light is blinking.
If the Monitor does not call out
Perform previous steps. Perform the “#999” test call operation on
the previous page.
Emergency Phone Call Sequence
Emergency Calls After
Power Outage 5 minutes
Temperature Immediately
All phone numbers are called. If the PIN number is not entered, the
monitor will wait 20 minutes and then begin calling all phone number
again.
Optional 20 / 30 Hour Extended Batteries
If your unit has been ordered with an extended battery, it is installed
at the factory. These batteries are trickle charged and can take up
to a week to reach full capacity. The battery is charging whenever
the monitor is powered on.
Some Helpful TIPS
•If the Temperature Guard is having trouble receiving your pro-
gramming entries, try holding the button for a longer amount of
time.
•Include all necessary digits for phone numbers. Long distance
numbers must include 1 and the area code.
•Do not place the unit in direct sunlight as this will effect the tem-
perature and humidity readings.
•Do not place the unit near heating or cooling sources if you wish
to monitor the average temperature of a room.
•Placing the unit on the floor will cause the Temperature Guard to
sense a temperature that is lower then the actual ambient tem-
perature.
•To monitor the power status of specific devices; connect the
Temperature Guard’s power plug into the same power source as
the device you wish to monitor. It is possible for an isolated
power outlet to lose power.
