Learn Mode Rate of Rise Heat Sensors
Installation Instructions

Note: Battery life depends on how often the sensor transmits

Introduction

This is the Learn Mode Rate-of-Rise Heat Sensors
Installation Instructions. The sensors (Figure 1) combine a

Chemetron heat detector and a learn mode wireless
transmitter in one unit. A built-in thermostat trips the transmitter
when the temperature at the sensor location reaches about
135°F (57°C) or 200°F (94°C), depending on the model
installed.

signals, but is more dependent on the temperature of the
installation environment. Alkaline batteries self-discharge more
rapidly when used in high temperature environments.

When the battery voltage gets low, the sensor transmits a low
battery signal to the panel. The panel then activates sirens with
trouble beeps to notify the customer that the sensor battery
must be replaced

Caution: SX-V Special panels must have software version 8.0

or later installed for correct response from the sensors. Do not
install Learn Mode Rate of Rise Heat sensors if the panel an
earlier software version. Contact Interlogix technical support at

888.437.3287 for assistance.

Since many fires grow rapidly in intensity causing a rapid
temperature increase, the thermostat also trips the transmitter
if the temperature rises 15°F (8°C) or more per minute.

All models can be powered by one 9-volt alkaline battery that
can last 12 to 18 months, or by one 9-volt lithium battery that
can last up to twice as long.

Installation

Use the following installation guidelines:

• Heat sensors should be installed to provide property
protection. Reliance should not be placed on heat
detectors for life safety. Where life safety is involved,
smoke sensors must also be installed.

• The sensors allow for normal temperature fluctuations,
however, ceiling temperatures should not exceed 100°F
(37°C) when installing 135°F models, or 150°F (66°C)
when installing 200°F models.

• Mount the sensor in a central location of the area to be
protected, either on the ceiling or on a wall.

• If mounting on a ceiling, the sensor must be at least 4 in.
(10 cm) away from any walls.

• If mounting on a wall, the top of the sensor must be within
4 to 6 in. (10 to 15 cm) of the ceiling.

• The UL maximum spacing allowance of the sensor is 50 x
50 ft. (15 x 15 m). Refer to the NFPA Standard 72 for
application requirements.

P/N 46-547 • REV • October 2012 1

• Do not mount the sensor close to devices that change
temperature rapidly, such as ovens, heat vents, furnaces,
or boilers.

Equipment needed

You will need the following equipment to install the sensors:

• Phillips and flathead screwdrivers

• Appropriate learn mode control panel documentation (for

programming information)

Programming

Testing

Before permanently securing the sensor to the wall or ceiling,
test the sensor from the installation location using one of the
following methods.

Caution: The test method described only tests rate-of-rise

operation. These sensors cannot be field tested for their fixed
temperature ratings without being destroyed. When used with
care, the heat from a portable hair dryer (method 2) can be
used for testing. Do not aim the hair dryer directly at the round
disc on the sensor as this can cause it to pop off. If this
happened, the sensor must be replaced.

The panel must learn (program) the sensor ID code in order to
respond to sensor signals. For complete programming
information, refer to the specific control panel documentation.

To add the sensor to panel memory, do the following:

1. Separate the sensor from the base by twisting the sensor
counter-clockwise and pulling the sensor off the base. Set
the base aside.

2. Place the panel in program mode.

3. Proceed to the Learn Sensors menu. When the panel
prompts you for a sensor group number, enter the group
number (26).

4. Select the desired sensor number.

5. When the panel prompts you to trip the sensor, press and
hold the learn switch on the sensor (Figure 2) until the
panel beeps, indicating successful programming.

Method 1

To test the sensor, do the following:

1. Place the panel in sensor test mode.

2. Rub your hands together vigorously, until they feel hot.

3. Place the palm of one hand on the round disc of the
sensor, for about 7 to 10 seconds.

4. Listen for the appropriate number of beeps from interior
sirens and speakers (refer to the specific panel
documentation).

5. Exit sensor test mode.

The sensor should reset in less than one minute.

Method 2

To test the sensor, do the following:

1. Place the panel in sensor test mode.

2. Plug in a portable hair dryer.

3. Hold the hair dryer about 12 to 18 in. away from the
sensor, aiming it at the side of the sensor.

4. Listen for the appropriate number of beeps from interior
sirens and speakers (refer to the specific panel
documentation).

5. Exit sensor test mode.

The sensor should reset in less than one minute.

6. Exit program mode.

Mounting the sensor

To secure the sensor to its permanent location, do the
following:

1. Locate the base mounting holes (inner pair and outer pair)
and mount the base to the wall or ceiling with the
appropriate hardware (Figure 3).

2. Attach the sensor to the base.
