TA1 Temperature and Alarm Sensor
Installation Guide
Caution
Failure to follow these instructions can damage the product or cause a hazardous
condition. Disconnect power during the installation of this product. All wiring must
conform to local codes and ordinances. The TA1 sensor is designed for use with a 24
VAC Pelican thermostats only. After installation, if the TA1 Sensor does not show up on
your Pelican Site Manager you will need to contact Pelican Wireless Support and
request a thermostat TS200(H) upgrade.
Mount the back plate ofthe TA1 sensor to a flat surface. Position it so that wires can be fed
through either the oval opening in the back or the small opening on the bottom of the TA1
sensor. Drill 3/16" holes into the wall at the provided mounting locations on the TA1 sensor.
Insert anchors into the wall and attach the back plate to the wall using the included mounting
screws. Follow the wiring instructions on page 2.
After the TA1 sensor is mounted simply lineup the front cover to the back cover and snap
into place. To remove the front cover from the back plate,use a flat head screw driver and lightly
twist in the provided slots on each side of theTA1 sensor.
The Temperature and Alarm sensor is
an add-on accessory to the Pelican TS200
and TS200H Thermostats.
Uses:
1. External Temperature Sensing
2. Refrigeration Monitoring & Control
3. Dry Contact Alarm Interface

The TA1 sensor requires 3-wires for power and communcation with a TS200(H); as shown
in the diagram above. In many situations you will be able to simply mount the TA1 sensor
on a wall and use the provided 10K internal temperature sensor to detect the temperature
at the desired location.
Follow the guide on page 3 for alternate installation options for the TA1 sensor. The TA1
sensor can be installed at a maximum distance of 500'from a TS200(H). A 10K external
temperature probe can be connected to the TA1 sensor up to 100' away.
We always recommend using a Pelian certified external temperature probe. Contact your
local Pelican Wireless distributor for assistance.

For installations where 3-wires already exists or can be run
from a TS200(H) thermostat to the TA1 sensor. Mount the TA1
sensor directly on the wall. Connect TA1 sensor’s D, C, and R
terminals to macthing terminals at TS200(H). 500' maximum
distance.
Applications:
– Detect temperature inside of an enclosed refrigerator or
freezer.
– Install the TA1 sensor on the wall with the thermostat placed
in a secure location.
Remove the internal temperature sensor from the “T” terminal
of the TA1 sensor. Connect the external temperature probe to
the TA1 sensor’s “T” terminal. 100' maximum distance.
Connect the TA1 sensor’s D, C, and R terminals to matching
terminals of the TS200(H).
The following wiring options should be used to determin the proper wiring approach for your
application. This guide shows the most common configurations. Contact Pelican Wireless
Systems for assistance with configurations not shown on this guide.

Remove Wiring Module from the TS200(H)
thermostat. Install Wiring Module inside of
the air ahndler.
Refer to page 4 of a TS200(H) Installation
Guide.
Some installations may have limited in-wall wiring. Use this configuration if no Data Wire or
Commmon Wire is available. A common application would be to monitor supply air temperature
with limited wires.
Login to your Pelican Site Manager Web Application. Select Admin > Thermostat Setup fpr
the thermostat which has the newly attached TA1. Scroll down until you see a category
labeled “Wired Sensor”
Select the correct Function for your TA1 sensor:
– “Temperature” to use the TA1 sensor instead of the thermostat’s internal temperature
sensor or to allow averaging between the TA1 sensor’s temperature sensor and the
thermostat’s temperature sensor.
– “Alarm” to use the TA1 sensor as an interface for a Dry Contact alarm input. Select whether
a notification should be sent when the contact is opened or closed.
– “Temp Monitor” use the TA1 sensor as a stand alone temperature monitoring device.
(ie. supply air temperature or outside air temperature monitoring).
For additional assistance visit www.PelicanWireless.com to request support.
Connect the R, C, and D terminals from the
Wiring Module to matching terminals on the
TS200(H).
Connect the R, C, D terminals from the
Wiring Module to the matching terminals on
the TA1 sensor.
Note: The sensor can then be used for any one of
the three examples shown on page 3.
