Fire alarm systems
Multi detector
4350
•
Low profile design / Unleaded soldering / Latest IC technology
•
One detector housing, two detector types and AI function
General
This low profile multi detector contains one
photoelectric (optical) smoke detector and
one heat detector within one housing. The
latest IC technology is used to secure the
highest reliability possible.
In the
smoke
detection chamber is a high-
efficient optical system consisting of an
LED and a photodiode with two lenses.
Scattered light (i.e. reflection of infrared
light) is used to detect smoke.
The
heat
sensing element is a thermistor.
Reduces false fire alarms
The smoke enters the detection chamber
through an insect filter and an optical
labyrinth. This construction not only
improves the smoke inflow but it also causes
steam, fog, etc. to condense into moisture on
its surfaces, to prevent false (nuisance)
alarms.
The detector maintains a constant sensitivity
regardless of the contamination. It has also
a self diagnosis of the internal devices.
AI function
•
Combined heat and smoke sensing
will
guarantee reliable and accurate fire alarm
detection.
•
Variable delay function
, i.e. the delay
time before fire alarm is activated, is
influenced by temporary changes of the
temperature and the smoke obscuration.
•
Learning function / condition
means
that the detector will adapt an alarm
algorithm according to the smoke and/or
temperature conditions where the
detector is located, i.e. temperature
changes and occurrence of smoke. There
is a normal algorithm (default) and there
are less and more sensitive learning
conditions (algorithms) that will be
adapted after a learning period. If the
conditions changes, the normal will be
adapted again.
Environment friendly
The detector has unleaded soldering
. The
latest IC technology reduces the number of
semiconductors and other electronic
components to a minimum.
Compatibility
The conventional multi detector 4350 is the
best substitute for the ionization smoke
detectors 2316 and 2317.
Miscellaneous
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 2216 / 2217.
Product applications
The detector is intended for indoor use and
in dry premises. It is excellent to detect all
types of fires, also a methylated spirits fire.
Used in the systems
EBL500
/ 512 / 128 /
1000 / 2000.
