INTRODUCTION
The Temp˚Alert ® has been designed for reliable monitoring of non-condensing (indoor only) environment
areas where high and low temperature limits are critical.
Select an acceptable temperature range by setting the adjustable high and low limit arms. If the monitored are
temperature either rises or falls to the limit arms, the temperature indicator will contact one of the limit arms.
This completes the circuit and provides you with a dry contact alarm signal. The TA-1 contacts are normally
open (N.O.) dry contacts rated at 50mA at 12 VDC . This output can be used to activate alarm systems, telephone
dialers, or other remote warning devices. Temp˚Alert ® is the ideal addition for any security system.
LOCATION
In specifying the location and number of TA-1s to install consider room size, effectiveness of the ventilation
system, and critical monitoring areas. If the building already has an energy management system, an easy rule
of thumb to follow is to install a TA-1 near each thermostat. It should be mounted on a wall or other vertical
surface in the area where temperature is to be monitored. Make sure it is well clear of windows, doors, or heat
sources that could cause an inaccurate reading of air temperature. When protecting a building against freeze
damage, always install at least one Temp˚Alert ® on every level of the home or business.
INSTALLATION
Items needed:
· Standard screwdriver · 11/32” wrench · 22-18 AWG twisted pair
STEP 1 – ATTACH TA-1 TO MOUNTING SURFACE
Position the mounting template in the desired location and mark the mounting holes. Depending on the type
of surface you are mounting to, you may need to predrill holes to accept the mounting screws alone, or use the
plastic anchors and mounting screws. Drive the screws into the mounting surface, allowing approximately 3/16”
between the screw head and the mounting surface. (See Mounting Template below.) Engage the key slots on
the back of the TA-1 case with the screw heads and press down.
STEP 2 – MAKING THE WIRING CONNECTIONS
Connect the TA-1 to your warning device by attaching a 22-18 AWG twisted pair cable from (2) front mounted
terminals of the TA-1 to an open zone on your alarm panel, telephone dialer, wireless transmitter, etc. See
Figure 1.
STEP 3 – SETTING THE HIGH AND LOW SET POINTS
Each limit arm is controlled by an adjustment screw. To set a limit arm, slightly loosen the appropriate locknut
(turn counter clockwise) with a 11/32” wrench (See Figure 2). Next, use a screwdriver to set the limit arm to the
desired temperature limit (See Figure 3). Once the arm is in the proper setting locations, retighten the locknut
(turn clockwise) (See Figure 4). Avoid over tightening of the locknut. Repeat this process until both temperature
limits have been set. Make sure to retighten the locknut when temp limits have been set. The TA-1 will not
function properly if the locknut is not retightened.
To insure proper operation, test weekly.

OPERATION AND TESTING PROCEDURES
To manually activate the TA-1 for testing, loosen the locknut of one limit arm and use a screwdriver to move
the limit arm toward the temperature indicator until it makes contact and temporarily tighten the locknut. If
installed correctly, this test procedure should activate the warning device to which the TA-1 is connected. After
testing, loosen the locknut, return the limit arm to its original set point and tighten the locknut. The same test
procedure should also be repeated with the second limit arm to verify proper operation.

IMPORTANT:
Do not use the TA-1 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.
