LOCATION
In specifying the location and number of Temp˚Alerts® 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 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.
INSTALLATION
Items needed:
• Standard screwdriver
• 5/16” wrench or nut driver
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.
Diagram shown above will activate zone 1 if the high limit
is exceeded and zone 2 if the low limit is exceeded.

Operation and Testing Procedures
For proper operation, the MTA-1 must be located in an area
where the temperature range is within +30˚ to +100˚ F (+1˚ to
+38˚ C). 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.
