PRELIMINARY: TR-FFT Fire Fighter’s Telephone Manual — LS10309-001TR-E:A 04/28/2021
Section 2: Prerequisites for Installation
This Section of the Manual is intended to help you plan your tasks to complete the installation. Please read this Section thor-
oughly, especially if you are installing a TR-FFT for the first time.
2.1 Environmental Specifications
It is important to protect the TR-FFT control panel from water. To prevent the water damage, the following conditions should
be AVOIDED when you install the units:
•
Do not mount the panel directly on exterior walls, especially masonry walls (condensation).
•
Do not mount the panel directly on exterior walls below grade (condensation).
•
Protect the panel from plumbing leaks.
•
Protect the panel from splash caused by sprinkler system inspection ports.
•
Do not mount the panel in areas with humidity-generating equipment (such as dryers, production machinery).
When you select a location to mount the TR-FFT, the unit must be mounted where it will NOT be exposed to temperatures out-
side the range of 0°C- 49°C (32°F-120°F) or humidity outside the range of 10% - 93% at 30°C (86°F) non-condensing.
2.2 Preventing Water Damage
Water damage to the Fire Fighter’s Phone System can be caused by moisture entering the cabinet through the conduits. Con-
duits that are installed to enter the top of the cabinet are most likely to cause water problems. Installers should take reasonable
precautions to prevent water from entering the cabinet. The water damage is not covered under the warranty.
2.2.1 Removing the TR-FFT Assembly from the Housing
If it is necessary to remove the control panel assembly from the cabinet for repair, remove the screws that hold the control
panel in the cabinet. Do not attempt to disassemble the circuit boards.
