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 1234

075

1 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 entered  

• 

The Temperature Guard calls a voice number and contacts a person who enters the PIN number.            

 

How do I connect the Temperature Guard to a phone line which has a fax or answering 
machine connected to it? 

Program the Temperature Guard to answer after one more ring than the other device on the line.  This 
allows the other device to always answer first.    

To call and access the Temperature Guard  

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 Temperature Guard will answer. 

Example

: An answering or fax machine on the same line as the Temperature Guard and is set to an-

swer after 4 rings. 

Program the Temperature Guard to answer after 5 rings.   

To access the Temperature Guard, dial the number, let it ring three times, then hang up.  Wait 15 sec-
onds and call again.  After two rings, the Temperature Guard  will answer. 

 

How do I read the temperature from the blinking light? 

Wait for the light located next to the phone line to be on for approximately 2 seconds. 

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.  

Now count the number of blinks until the light is again off for 1 second.  This is the 1’s digit of the tem-
perature. 

The temperature is calculated by: (multiply the number of blinks counted in step 2 by ten and then add 
the number of 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. 

 

Where is my 20 / 30 Hour extended battery? 

If your unit has been ordered with an extended battery, it is installed inside the Temperature Guard at 
the factory.
