INSTALLING THE TTDM-128
THERMAL BUILDING SOLUTIONS
IMpORTANT: The TTDM-128 is an electronic unit. During installation, take the following
precautions to avoid damage to its electronic components:
• To avoid damage to the unit, store the TTDM-128 module in its cardboard box until
construction is complete.
• Handle with care, avoid mechanical damage.
• Keep the electronics dry.
• If handling circuit boards, hold them by their edges to avoid physical contact with electronic
components.
• Avoid exposure to static electricity.
• Avoid contamination with metal filings, liquids, or other foreign matter.
Select the mounting position.
Choose a location indoors where the module will be protected from the elements and temperature
extremes. Follow all national and local codes and regulations applicable to the installation.
• Remove the module from its carton. Do not remove the protective film from the membrane
on the front of the unit.
• Open the enclosure door using a flat-blade screwdriver or a coin.
WARNING:
IGNITION HAzARD. Do not mount the TTDM-128 unit in a hazardous location. Sensing cable
connected to the TTDM-128 may (subject to approvals restrictions) be located in hazardous
locations, but the module itself must be in an ordinary area.
IMpORTANT: The TraceTek sensing circuit is power limited, so the TraceTek leader or jumper
cable and the power supply cable must not run in the same conduit.
Mounting the Enclosure
Install the enclosure using four screws (selected by installer) in the prepunched 8 mm (5/16-inch)
mounting holes with centers as shown in Figure 3. If plastic plugs are in the mounting holes,
remove them.
Make sure the rubber elastomeric washers (provided in the shipping box) are aligned to seal
around the mounting screws to maintain the TypE 12 and Ip54 ratings.
