temperature is correct and stable.
(2). From a distance of several inches, direct the airflow
at the guard protecting the thermistor. The detector
should alarm within 30 seconds.
(3). Upon alarm immediately remove the heat source
and check that the red LED of the detector is
illuminated. Reset the detector from the control
panel.
(4).
If a detector fails to activate within 60 seconds, confirm
connections and programming. If necessary replace and return to
distributor for recalibration.
(5). After testing, check that the system is set for
normal operation and notify the appropriate
authorities that the testing operation is complete
and the system is active again.

NOTE
This heat detector is particularly designed to
initiate and
activate
emergency action, but will do so only when it is
used in conjunction with an authorized fire alarm system.
This detector must be installed in accordance with Local Fire
Authority recommendations.
Heat detectors are primarily designed for property
protection.
For Life protection early warning is required,
this can be obtained by the installation of appropriate Smoke
detectors. (GFE-CS) Heat detectors do not provide early
warning of fire and cannot detect smoke, gas, combustion
particles, or flame. They will alarm when the temperature at
the heat detector reaches 57
o
C (135
o
F) or above. Given the
rapid growth of certain types of fires, heat detectors cannot
be expected to provide adequate warning of fires resulting
from smoking in bed, inadequate fire protection practices,
violent explosions, escaping gas, and improper storage of
flammable liquids like cleaning solvents, other safety
hazards, or arson.
Heat detectors are components in professionally installed fire
alarm systems.
They will not function if they have been
improperly wired into the fire alarm system or if power to
them is disconnected for any reason.
Heat detectors
should be tested and maintained following
the instructions in this manual. To be safe, they should be
replaced after they have been installed for ten years.
Note: This product is factory sealed and does not
contain user serviceable parts. Opening THE DETECTOR
HEAD WILL VOID THE WARRANTY.
