Product Summary
The Learn Mode Rate-of Rise Heat Sensor combines a
Chemtron Model 601 detector and an ITI learn mode
wireless transmitter in one unit. A built-in thermostat
trips the transmitter when the temperature at the sen-
sor’s location reaches about 135°F.
Since many fires grow rapidly in intensity causing a
rapid temperature increase, the thermostat also trips
the transmitter if the temperature rises 15°F or more,
per minute.
The sensor is powered by a 9-volt battery (see note),
either alkaline or lithium type. The alkaline battery
can last 12 to 18 months. The lithium battery can last
twice as long as the alkaline type.
When the battery voltage gets low, the sensor sends a
low battery signal to the panel. The panel then acti-
vates sirens that emit trouble beeps to notify the cus-
tomer that the sensor’s battery must be replaced.
Note
Battery life depends on how often and length of time bat-
tery is used.
CAUTION:
SX-V
Special
panels must have software
version 8.0 or later installed for correct
response from Learn Mode Rate-of-Rise
Heat Sensors. Do not install Learn Mode
Rate-of-Rise Heat Sensors if the panel
uses an earlier software version. If you
need assistance, please call ITI Technical
Services at 1-800-777-2624.
Equipment Needed
•
Phillips or flathead screwdriver
•
Appropriate learn mode control panel installation
instructions (for programming information)
Installation Guidelines
Use the following guidelines when installing the
Learn Mode Rate-of-Rise Heat Sensor:
•
Heat sensors should be installed to provide prop-
erty protection. Reliance should not be placed
only on heat detectors for life safety. Where life
safety is involved, smoke sensors must also be
installed.
•
The sensor allows for normal temperature fluctu-
ations; however, ceiling temperatures should not
exceed 100°F.
•
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 inches away from any walls.
If mounting on a wall, the top of the sensor must
be within 4 to 6 inches of the ceiling.
•
The UL maximum spacing allowance of the sen-
sor is 50’ x 50’. Refer to NFPA Standard 72 for
application requirements.
•
Do not mount the sensor close to devices that
change temperature rapidly, such as ovens, heat
vents, a furnace, or boilers.
Programming
The panel must learn the sensor’s ID code in order to
respond to sensor signals. For complete programming
information, refer to the installation instructions for
the specific panel.
To add the sensor to panel memory:
1)
Separate the sensor from the base by twisting the
sensor counter-clockwise and pulling it off the
base. Set the base aside.
2)
Place the panel in program mode.
3)
Enter the LEARN SENSORS mode.
4)
When the panel prompts you for a sensor group
number, enter the number for the fire group.
5)
Select the desired sensor number.
