Winland Electronics TA-40 - Manual (Page 2)

NTRODUCTION
Thank you for your purchase of the Winland Temp˚Alert® model TA-40. Your new Temp˚Alert® has been designed for
reliable monitoring of areas where low temperature limits are critical. Temp˚Alert® monitors and activates when the
temperature drops below 39.2˚ F (4˚ C).

OCATION
It is difficult to precisely specify the location or quantity of TA-40s to install. A number of factors such as room size,
effectiveness of the ventilation system, and the likelihood of freezing should be considered. If the building already has
an energy management system, an easy rule of thumb is to install a TA-40 near each thermostat. When protecting a
building against freeze damage, always install at least one Temp˚Alert® on every level of the home or business.

NSTALLATION
Items needed:
• Either Standard or Phillips screwdriver
• Quantity of two (2) #6 Screws
• 22-18 AWG twisted pair
Step 1
Use the base of the TA-40 as a template and mark the position of the screw holes. Drill pilot holes if necessary.
Align the TA-40 with mounting holes and install the screws. Do not fully tighten screws at this time.
Step 2
Connect the TA-40 to your warning device by attaching an 22-18 AWG twisted pair cable to the terminals. Slide
the cover on and finish tightening the mounting screws.
Operation and Testing Procedures
The TA-40 must be located in an area where the temperature range is within -40˚ to 212˚ F (-40˚ to 100˚ C). Contacts
will remain closed at temperatures above 39.2˚ F (4˚ C). But if the temperature drops below 39.2˚ F (4˚ C) the
contacts will open to activate any hardwire alarm or wireless transmitter. The tolerance on this temperature switch is
±5.4˚ F.
To manually activate the TA-40 for testing purposes, place the device in a freezer for 10 minutes. Remove the TA-40
from the freezer; test the contacts with an ohmmeter to confirm they have opened.
To insure proper operation, test weekly.

:
Do not place any Temp˚Alert® in a cooler or freezer. Frost buildup and
moisture can cause the unit to malfunction. For cooler & freezer
applications, use an EnviroAlert® device with a remote probe.
