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 TR44T 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.
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 TA44R receiver can be located up to 100 ft (30 m) from the transmitter. 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 button 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 TR44R 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.
USING MULTIPLE TRANSMITTERS
Multiple TA44T transmitters can be used to monitor separate locations. Only a single receiver is required to receive the alarm signal from any
of the transmitters. If any transmitter generates an alarm condition, the TR44R receiver will sound the audible alarm.

TA44 User’s Guide Rev 030310 Page 2/4
USING MULTIPLE RECEIVERS
Multiple TA44Rreceivers can be used in different locations to monitor one or more TR44T units remotely. If any of the TR44T units generates
and alarm condition, all the TA44R receivers will sound the audible alarm.
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 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 (220V available) 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 TA44R in the desired location. Plug the TA44R into a 120VAC (220V available) 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.
The TA44T is set at the factory to alarm on a RISE above the set temperature, after a one-hour delay. The OVER/UNDER Switch is in the OVER
position and the DELAY/NO DELAY switch is set to the DELAY position.
To change the operation of the TA44T, remove the switch cover. SW1 controls the DELAY/NO DELAY operation. Setting this switch to NO
DELAY will activate the audible alarm and the N.O. relay switch as soon as the probe temperature reaches the set point temperature. SW2
controls the OVER/UNDER operation of the unit. Setting this switch to OVER will cause the alarm to be activated when the sensor temperature
rises ABOVE the temperature setpoint. Setting this switch to UNDER will cause the alarm to activate when the sensor temperature falls
BELOW the temperature set point. SW3 controls the temperature units displayed (°F or °C).
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.
