General Description
The Refrigerator/Freezer or Property Guard is a complete multiple device monitor and alarm
system with integrated auto-dialer, Ethernet port and on board data logging. Through the
rest of the manual the Refrigerator/Freezer or Property Guard will be referred to as Guard.
The Guard monitors up to eight (8) temperature sensors, an unlimited number of magnetic
door sensors and power.
The Guard has programmable high and low temperature limits and an alarm time delay for
each sensor. An identification message can be recorded for each sensor, indicating where
the sensor is located to allow a quick response to a problem. The Guard has numerous op-
tions that allow it to be configured for any application.
The Guard can monitor doors with its dedicated door sensor inputs. A time delay can be
programmed, enabling a freezer door to be left open for a maximum amount of time before
the buzzer is activated and the Guard begins its alarm procedures.
The Guard has an internal buzzer and an alarm relay that can be programmed to turn on or
off when the temperature of any location is out of limits for greater than the alarm time delay
or if a freezer door has been left open.
The Data Capture 5 (Rev 5.4.7 or higher required) software stores data internally and may
be downloaded any time from www.temperatureguard.com With the Data Capture soft-
ware you can also regularly collect data across your LAN and store readings on a PC. Also,
alert emails can be sent out to alert staff to temperature issues. A built-in web server allows
you to use a simple web browser to check the temperatures by entering the IP address of
the device into a web browser.

Installing the Guard:
 Immediately upon removing the Guard from the box, turn it on without plugging it in to the wall out-
let. This is a test to see if the batteries became dislodged during shipping. If the LCD screen
works, turn it back off. Newer units (rev. 13 and up) have the power switch built into the power
jack. Simply plugging in the cord to the jack enables the switch.
 Select a location with access to power and an analog telephone line.
 Mount the Guard to the wall. Holes are 10cm or 3.937 inches apart.
 Connect the phone line to an active analog telephone jack.
It is recommended that a surge suppresser be used for the phone line.
 Plug the Ethernet cable into the LAN jack. Required if on DHCP network.
 It is recommended that a surge suppresser be used for the power line.
 Plug the power pack into a 120vac power.
 Connect Sensors and Inputs.
For ease of wiring, the terminal blocks can be removed. Follow the wiring diagram on the previ-
ous page.
Temperature Sensors
Locate the sensor so that it will yield an average temperature. If specific items within a fridge or
freezer are being monitored, locate the sensors as close as possible to those items. The tempera-
ture throughout a fridge or freezer can vary widely.
Door Sensor Inputs
Wire closed loop magnetic door sensors to the Door Sensor Inputs to detect when doors are
open. Multiple door sensor switches can be wired in series.
Temperature Sensors must be installed before turning on the unit.
 Turn on the Guard by moving the power switch to the “On” position. If sensors are added or re-
moved later, you must turn the unit off, then on again. Newer units (rev. 13 and up) have the
power switch built into the power jack. Simply plugging in the cord to the jack enables the switch.
Removing the jack will turn the unit off.
Connecting the Guard to your network:
Important
 Download the Data Capture software from:
http://temperatureguard.com/software.html
 Read the installation instructions before installing!
 Read the manual before continuing.

rings (Default is 1).
2) To access all functions, enter the 4-digit "Full Access" PIN. (Factory default is 0000). To access
only the "Acknowledge Only" functions, enter the 4-digit “Acknowledge Only” PIN (Factory default
is 1234).
The "Acknowledge Only" functions are:
A) Confirming Alarm Conditions Remotely.
B) Checking Sensor Inputs Remotely.
3) You will hear the Main Menu options:
Programming Temperature Sensor Parameters
Each temperature sensor has four (4) programmable parameters as well as a programmable tem-
perature correction.
Sensor Identification Message. The Sensor ID message will be played when the Guard is report-
ing the status of that Sensor. (This must be done over a phone line)
Sensor Low and High Temperature limits. The low and high temperature limit values are pro-
grammed in degrees. When a sensor's temperature exceeds either the high or low limit for longer
than the programmed callout time delay, that sensor will be in alarm condition. These values can
also be programmed using the Data Capture Software (quicker and easier).
Sensor callout time delay. A sensor's temperature must be out of limits for greater than the callout
delay time for the sensor to be in alarm condition. These values can also be programmed using the

Frequently Asked Questions
Newer units do not have a power switch, how do I turn it on and off or reboot it? (rev. 13 and
up)
The power switch is built into the power jack. Unplug the power cord from the jack at the unit. Un-
plugging the unit from the wall will not reboot the unit as the internal batteries will keep it going.
How do I set the Guard to DHCP?
Guard must be plugged in and network cable attached to the network.
Turn the Guard off. Hold down the Alarm Cancel button and turn the Guard on. The screen will dis-
play Release Pushbutton. Release it before the 5 second countdown. The screen will display Reset
to DHCP? No Pressing and releasing the button again will toggle the No to Yes. Let it boot up while
the Yes is displayed and it will be in DHCP mode.
When does the Guard callout?
The Guard will callout when any input (temps, doors, power) is in an alarm condition and has not been
confirmed.
When an alarm condition first occurs, the Guard turns on the alarm relay and buzzer, and then waits
the Unit Callout Time Delay (2 minutes by default) to allow local personnel time to react to the alarm.
(Alarm relay does not come on in a power outage condition).
When is a sensor/input in alarm condition?
When a temperature sensor has been out of limits for greater than the programmed time delay.
When a temperature sensor opens or shorts after having been connected.
When a door sensor has been open longer than the programmed time delay.
When the power has been out for greater than the power outage time delay.
What happens when the Guard calls?
1) The Guard will dial the contact number exactly as it was programmed.
► If the contact number was programmed as a pager number (* is the first digit. The Guard will
dial all digits following the *.
2) The Guard will wait for a person or voice mail system to answer the call.
3) The Guard will beep while it waits for a person to stop speaking or the voice mail system's outgo-
ing message to stop.
4) For voice contact numbers, the Guard will play the recorded personal identification message.
For pager contact numbers, the Guard will print the Local Identification number on the pager
screen. The Guard will then hang up and call the next programmed contact number.
5) The Guard will report any alarm conditions (i.e. “Warning, Sensor 2, “sensor 2 recorded mes-
sage”, is 89 degrees and has been out of limits for, x hours and y minutes.”
6) The Guard will ask for the PIN number.
Once the PIN number has been entered, the Guard will not call again because the current alarm con-
dition has been acknowledged, unless the alarm still exists and the reminder call has been enabled.
If the correct PIN number is not entered within 4 seconds the Guard will repeat the warning message.
This warning message can be repeated up to 2 times by changing the programmed value. See the
Programming Repeat Warning Messages section.
If the correct PIN number is not entered the Guard will call the next programmed contact telephone
number.

19
If the Guard has called all programmed contact numbers without having the correct PIN number en-
tered, it will wait 20 minutes and repeat the sequence until the alarm condition goes away or the Guard
receives confirmation either locally or remotely.
How can I connect the Guard to a Phone Line which has a fax or answering machine connected
to it?
Program the Guard to answer after one more ring than the other device. This allows the other device
to always answer first. To call and access the 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 phone number again.
4. The Guard will answer.
For Example:
A fax machine on the same line as the Guard is set to answer after 4 rings. The Guard is programmed
to answer after 5 rings. To access the Guard, dial the number, let it ring three times, then hang up.
Wait 20 seconds and call again. After two rings, the Guard will answer.
What is the difference between the different models?
The VM605E and the V610E have network adapters on them, allowing the use of the Data Capture
software and onboard data collection.
The VM605 and the VM605E are calibrated for refrigerators and freezers.
-148°F to 69°F is the calibrated range.
The VM610 and the VM610E are calibrated for refrigerators and incubators.
32°F to 147°F is the calibrated range.
How do I delete a phone number?
See page 11 step 8
How do I remove a sensor without it alarming constantly?
See page 5
Can I set the IP address without your software?
Yes. Open a browser and type the following, changing the IP address to the IP address of your unit.
http://192.168.0.73/secure/ltx_conf.htm (this is an example) Default login name and password are
both blanks. Enter nothing, just hit enter.
Telnet may also be used. From a cmd prompt, telnet 192.168.0.73 9999 (again this is an example)

The rechargeable batteries used in the Guard are trickle charged and can take up to 48 hours to reach
full capacity. The batteries are charging whenever the monitor is powered on.
What happens when the power goes out?
The Guard will wait the programmed power outage delay and then begin making calls.
Please note the Guard does not power the Ethernet Port with the back-up battery, therefore there will
be no communication via a computer during a power outage. Door sensor inputs are not monitored
during a power outage as well.
Troubleshooting
Verifying telephone communication
To verify telephone communications, perform the following test.
1) Using another phone line, call the Guard and verify that it answers the phone.
2) Verify at least one telephone number has been programmed.
3) Hang up.
4) Call the Guard again.
5) Enter #999 for the PIN. (including “#”, pound sign)
6) Hang up.
7) The Guard will perform a test call to your programmed telephone number's.
► Do not enter your PIN if you would like the Guard to continue calling any remaining pro-
grammed telephone numbers.
8) Watch the display and note any messages present.
If the Guard does not answer the phone
Verify that the phone line is a standard analog telephone line. Digital phone lines are not compatible
with the Guard. Use a DSL filter if your phone service is DSL.
Verify that the phone line is working. Connect a standard phone to the line intended for the Guard.
Verify that there is a dial tone.
Check that the phone line is plugged in securely.
Verify that the Guard is powered up and some data is being displayed on the display.
