Learn Mode Freeze Sensor Installation
Instructions
Overview
The ITI Learn Mode (LM) Freeze Sensor contains a thermal
couple wired to a transmitter. The LM Freeze Sensor detects a
furnace failure in a home or business. It activates a switch
(thermal couple) when the surrounding temperature drops to
~45°F. After the sensor is tripped, a temperature between 55°F
and 60°F is necessary for the device to send a restore signal.
The LM Freeze Sensor:
•Contains an RF transmitter capable of transmitting over
500 feet.
•Is powered by a 3.5-Vdc lithium battery, which lasts 5-8
years.
•Sends a Trouble (Low Battery) report to the CPU.
•Sends a supervisory signal to CPU every 64 minutes.
•Has an operating range of 10°F to 120°F.
•Contains a built-in tamper switch. Remove the sensor
cover to trip the switch. The sensor then transmits a
Trouble signal to the CPU.
•Has a tamper switch, which cannot be disabled.
•Monitors an open area of about 900 square feet (30’ x
30’).
Installation Considerations
DO
•Try to keep sensors within 100 feet of the CPU. The 100-
foot distance recommendation is given as a starting
guideline. The transmitter has an open-air range of over
500 feet, but the installation environment may affect this
range.
•Locate the sensor in an area that is likely to get cold first.
•Locate the sensor on an interior wall where there is free
movement of air.
DO NOT
•Locate the sensor in the same room as a furnace, water
heater, or any other heat source that may stay warm after
the furnace fails.
•Locate the sensor on an outside wall or near the
basement floor.
•Place in areas with excessive metal or electrical wiring.
These items may inhibit the sensor’s signals from reaching
the CPU.
•Place sensor in an area where it will be exposed to
moisture.
•Place the sensor in an area where the temperature will fall
outside the sensor’s operating limits (10°F-120°F).
Installation
CAUTION: You must be free of all static electricity when
handling transmitters. Touch a grounded metal object
before handling the circuit board. Handle the circuit board
by the edges and never set the circuit board on any
metallic surface.
1. Press on the cover end to disengage the top of the cover
from the slot in the sensor base, and then remove the
transmitter cover.
2. Remove the circuit board from the transmitter base by
pushing back on the base release tab. See Figure 1.

3. Place transmitter in sensor cover to protect circuit board
against static damage.
4. Secure the sensor base to mounting surface by using #6
pan head screws or #18 x 1/2” wire nails (brads). If
mounting on plaster, use the appropriate fasteners. Use
the slotted mounting hole for alignment. See Figure 2.

5. Replace the sensor circuit board on the base. Place the
reed switch end in first, then snap the board in place at the
base release tab.
6. Do not replace the sensor cover at this time.
Programming
General guidelines for programming this divce are:
1. Set the CPU into Program Mode.
2. Trip the device’s tamper switch. See Figure 1.
3. Replace the sensor cover.
Note: Refer to the appropriate CPU installation manual for
specific instructions for programming device into the CPU.
Testing
General guidelines for performing a Dealer Signal Strength
Test are:
1. Using the appropriate touchpad for the CPU, enter the
applicable Dealer Sensor Test code.
2. Cool thermal couple with a piece of ice in a plastic bag.
When the thermal couple reaches ~45°F, the transmitter
sends an RF signal to the CPU.
3. Note the number of beeps from the CPU. These beeps
indicate the device’s signal strength.
4. The device resets when the surrounding temperature
reaches 55°F-60°F
