A linear heat detector is a normally open
device that closes when subjected to heat. The
device is comprised of two internal coiled
spring loaded conductors. The Amerex linear
heat detector is green in color and has a
temperature set-point of 356°F [180°C]. The
linear heat detector can be routed throughout
the hazard areas over likely ignition and fuel
sources. When the ambient temperature rises
above 356°F [180°C], the insulation
surrounding in the internal coiled conductors
melts away allowing the two conductors to
come in contact with each other which
actuates the fire alarm signal. The protective
spring covered linear detector is recommended
for all off road use and other severe service
applications to protect against abrasion and
impact.
