OCATION
In specifying the location and number of Temp ̊Alerts® to install consider room size,
effectiveness of the ventilation system, and critical non-condensing (indoor only) environment
monitoring areas. If the building already has an energy management system, an easy rule
of thumb to follow is to install the MTA-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.

NSTALLATION
Items needed:
• Standard screwdriver
• 5/16” wrench or nut driver
• 22-18 AWG twisted pair
1 – Opening the Case
Begin with the device facing you. Turn the device 90 ̊ to the right to expose the left end of
the case. Notice the left end of the base plate has been tooled with a single attachment hole
whereas the right end has not. Grasp the device with your right hand, position your thumb
on the center of the left end of the device above the seam with your remaining fingers on the
right end of the device (See Figure 1). Press hard with your thumb to disengage the latching
pin. Separate the two halves by pulling the device away from the base plate.
2 – Attach Base Plate to Mounting Surface
After you have determined a location for the device to be mounted, position the base plate of
the device on the mounting surface with your hand and mark the center point of the mounting
holes with a pen or other marking device. Mount the base plate to the wall using the included
mounting screws. Depending on the type of surface you are mounting to, you may need to
predrill holes to accept the mounting screws alone, or the plastic anchors and mounting
screws.
3 – Select the High and Low Set Points
Each limit post is controlled by a locknut. Use a 5/16” nut driver or wrench to loosen (turn
counter clockwise) the high and low adjustment posts (See Figure 2). After loosening, slide
the posts to the proper temperature setting. Once the posts are in the proper setting locations,
simply retighten the lock nuts (turn clockwise). Avoid over tightening of the locknut.
4 – Making the Wiring Connections
To complete the installation, use three conductor stranded or solid wire to connect the MTA-1
to a control panel, dialer, etc. See Figure 3 for an example of a standard installation that utilizes
differentiated notification outputs for high and low temperature occurrences. If desired, the
HI limit wire and LOW limit wire may be connected together under a single zone. This is useful
whenever a limited number of open zones are available and you do not wish to differentiate
between a high and low temperature notification.
5 – Attach Front Cover to Base Plate
Grasp the device with your right hand by positioning your thumb on the center of the left end
of the device above the locking pin and positioning your remaining fingers on the right end of
the case (See Figure 1). Align the retaining tabs on the right edge of the case with the holes on
right edge of the base plate currently attached to the mounting surface. Press hard with your
thumb on the left end of the device and swing the device back toward the base plate until the
device seats properly into the base plate and the locking pin engages.
To open the case, squeeze
firmly with your thumb
and pull front face plate
away from the back plate.

See testing procedure. Operation and Testing Procedures
To manually activate the MTA-1 for testing, loosen the locknut of one limit post and slide
it toward the temperature indicator until it makes contact and temporarily tighten the
locknut nut. If installed correctly, this test procedure should activate the warning device to
which the MTA-1 is connected. After testing, loosen the locknut, return the limit arm to it
original set point and tighten the locknut. The same test procedure should also be repeated
with the second limit arm to verify proper operation.

MPORTANT
:
Do not use the MTA-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.
To insure proper operation, test weekly.
