Combination heat
detector 4318
General
Heat detector 4318 is a conventional combination heat detector, class A1R. It "gives
an alarm" at a certain fixed temperature
(59°C) and/or at a certain temperature rise,
"rate-of-rise" function.
The sensing element is a thermistor.
The detector is plugged in a conventional
base 2324 connected to a conventional zone
line input.
The base has an LED that will light when
the detector goes into alarm. In the base
there are terminals to connect an external
LED, e.g. 2218.
Environment friendly
The detector has unleaded soldering. The
latest IC technology reduces the number of
semiconductors and other electronic
components to a minimum.
Product applications
This conventional heat detector can be used
in the systems EBL500 / 512 / 128 / 1000 /
2000.
The detector is intended for indoor use and
in dry premises.
Heat detectors are normally used in small
rooms where the temperature can be
expected to rise rapidly in case of a fire or
places where smoke detectors can not be
used.
