TA44
Single Set Point Temperature Alarm With Digital Display
and Remote Wireless Alarm
Designed specifically for...
• REFRIGERATORS • FREEZERS • ENVIRONMENTAL CHAMBERS
...or any area where temperature change is critical.
The TA44T Temperature Alarm is a single point or threshold type of temperature alarm.
This type of temperature alarm monitors the temperature at the sensor probe tip and when this
temperature passes above (or below) the set point, the unit will execute a preset operation.
DISPLAY
The unit’s display shows the current temperature, the alarm set point temperature, the alarm
state, and the mode of operation of the unit (over temperature or under temperature alarm).
When the probe temperature reaches the set point, the unit will display its state as follows:
• In delayed alarm state the ALARM icon and the Bell will flash.
• In the alarm state the ALARM icon and the Bell will remain solid. The Bell clapper will
flash. Audible alarm will sound and the N.O. relay contacts will close. The unit will
transmit an alarm code to the wireless receiver, causing the remote receiver to activate
its audible alarm.
• If the Silence button is pressed during alarm condition, the audible alarm will turn off
and the N.O. relay contacts will open. The Silence button on the TA44T does not turn
off the audible alarm on the remote receiver. To turn off the audible alarm on the remote
receiver, push the remote receiver’s Silence button.
NOTE: This unit also has a concealed slide switch that allows for the alarm to be activated
immediately when the temperature has met the alarm threshold, if desired.

receiver, push the remote receiver’s Silence button.
NOTE: This unit also has a concealed slide switch that allows for the alarm to be activated
immediately when the temperature has met the alarm threshold, if desired.
INSTALLATION AND REMOTE ALARM OPERATION
The TA44T may be mounted to any flat surface, in any position, using the two holes provided
at the top of the case or with the supplied adhesive pads. Avoid mounting in areas of excessive
humidity or temperatures outside the operating range of the TA44T.
The R10 receiver can be located up to 500 ft (150 m) from the transmitter. This is a line of
sight distance. This distance can change if there are obstacles between the transmitter and
the receiver. To test that the receiver receives alarm messages from the transmitter, press and
hold the Silence button on the transmitter, while not in alarm condition. While the Silence but-
ton on the transmitter is held, the receiver should sound the audible alarm. When the Silence
button is released, the audible alarm on the receiver should turn off.
When the R10 receiver sounds an alarm, this alarm can be silenced by pressing the silence
button on the receiver. When the receiver received the No Alarm signal from the transmitter,
the silence state is reset, and the receiver returns to normal operation.
SENSOR EXTENSION
The TA44T sensor probe is designed to measure air temperature and may be mounted in any
convenient location in the area to be monitored. The sensor probe may be extended up to 200
feet with any 24AWG stranded wire.
RELAY CONTACTS
The TA44T may be connected to a remote alarm accessory, using the relay contacts provided
under the Switch Cover. Connections are provided for Normally Open or Normally Closed Dry
Contacts. Dry Contacts mean that no electrical power is supplied to the contacts and power
for a remote alarm or other device must be supplied externally. When an alarm occurs the N.O.
relay contacts will close and remain closed as long as the alarm condition exists. The relay
contacts will open if the user hits the Silence Alarm button.

OPERATION
Plug the TA44T into a 120VAC outlet and verify that the display shows the current temperature
and the Alarm set point. If the display is not on, the TA44T is not receiving power and is not
operating. For continued protection, this requires immediate attention.
Locate the R10 in the desired location. Plug the TA44R into a 120VAC outlet and verify that
the power light is ON. Test the remote receiver audible alarm as outlined above in the
INSTALLATION AND REMOTE ALARM OPERATION section.
Set the temperature alarm threshold to the temperature the TA44T must respond to, using the
Up and Down buttons. Typical values will be between 35 to 45 degrees for a refrigerator and 0
to 15 degrees for a freezer. The setting of this adjustment will depend on the type of protection
the TA44T is being used for and it is up to the judgment of the user to select an appropriate
alarm temperature.

Locate SW1, the switch on the left hand side. Note the lettering above this switch
(DELAY – NO DELAY). Setting this switch to DELAY will cause the TA44T to blink the ALARM
and BELL ICONS when the Sensor temperature passes the threshold set by the Front Panel
Adjustment. When approximately one hour has passed and the Sensor temperature has
remained past the threshold set by the Front Panel Adjustment, the TA44T will sound the
audible alarm, close the N.O. relay contacts, and transmit the alarm code to the remote
receiver. Should the temperature return to its normal value before this period has elapsed,
the one-hour delay will be reset. Setting this switch to NO DELAY will cause the TA44T to
sound an immediate alarm, close the N.O. relay contacts, display the ALARM and BELL ICONS
(Solid), and send an alarm code to the remote receiver, when the temperature passes the
threshold set by the Front Panel Adjustment. Should the temperature return to its normal value,
the TA44T will automatically reset, and send a no alarm code to the remote receiver.
Locate the terminal strip below the switches. This is where sensor probe, power supply and
remote alarm are connected to the TA44T. The TA44T comes from the factory with the power
supply and sensor probe attached. Note the 3 unused terminals on the right. These are the
relay contacts for use with external devices, such as remote alarms or automatic dialers.
Since each installation has different requirements, it is suggested you consult the instructions
supplied with any remote device prior to making any connections to the TA44T. Note the 5
Amp 120VAC rating of the relay contacts. PERMANENT DAMAGE will result if these limits are
exceeded.
TYPICAL CONNECTIONS ARE SHOWN IN THE DRAWING
USING MULTIPLE TRANSMITTERS AND RECEIVERS
Every TA44T transmitter and R10 receiver come preconfigured with a standard alarm
transmit code. This means that if multiple TA44T units are installed at a location, if any of
them generates an alarm, every R10 receiver at the same location will sound an alarm. When
more than one TA44T is installed at a location, it may be desirable for one or more
transmitters to transmit a unique alarm code, triggering different R10 receivers.

To change the alarm transmit code on the TA44T transmitter follow the steps below:
1. Make sure an alarm condition is not present.
2. Press and hold both the UP and DOWN buttons for about 5 seconds, until the unit
displays.
3. Let go of the buttons. The unit displays Pr, indicating that a new, random, alarm
code has been programmed into the unit.
To restore the unit to the factory default code, follow the steps below.
1. Make sure an alarm condition is not present.
2. Press and hold both the UP and DOWN buttons for about 5 seconds, until the unit
displays - - .
3. Continue holding the UP and DOWN buttons for 5 seconds more, until the unit
displays dF, indicating that factory default code has been restored.
4. Let go of the buttons.
Once the TA44T transmitter has been programmed with a new code, one or more R10
receivers have to be programmed with this code to receive the alarm message.
To synchronize the R10 receiver code to the TA44T transmitter code follow the steps below.
1. Make sure an alarm condition is not present. If possible, turn off any other TA44T
transmitters operating at the location.
2. On the R10 receiver, press and hold the Silence button until the Power and Alarm
indicators start to flash.
3. Let go of the Silence button.
4. On the TA44T transmitter press the SILENCE button for about 1 second and then
release it. The Power and Alarm indicators on the R10 should stop flashing and
the Alarm indicator will turn off.
The R10 receiver is now matched to the transmitter. To test communication, press and hold
the SILENCE button on the TA44T transmitter. The R10 should sound an alarm. Release the
SILENCE button on the TA44T transmitter. The R10 alarm should go off. If the test has failed,
repeat the synchronization procedure, from step 1.
