Fire alarm systems
Analog
multi detector
4300
•
Constant sensitivity / Service signal at a fixed level of contamination
•
New advanced algorithms and functions and yet compatible with older EBL systems
General
The multi detector contains one photo-
electric (optical) smoke detector and one
heat detector within the low profile housing.
The latest IC technology will secure the
highest reliability possible. It has
unleaded
soldering
. 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
smoke enters the detection chamber through
an insect filter and an optical labyrinth. This
construction not only improves the smoke
inflow, it also causes steam, fog, etc. to
condense into moisture on its surfaces, to
prevent false (nuisance) alarms.
The
heat
sensing element is a thermistor.
The detector is supplied with two LEDs that
will light when the detector goes into alarm.
The detector is plugged in the analog base
3312x / 4313. The COM loop is connected
to the base, which also has terminals for an
external LED, e.g. 2218. The detector is
intended for indoor use in dry premises and
in the systems
EBL512
/
128
/ 1000 / 2000
depending on the detector mode.
Constant sensitivity
The detector maintains a constant sensitivity
regardless of its contamination. A service
signal will be given when the detector has
reached a service level.
Address / Detector mode
The address setting tool 3314 is used to set
the detector's COM loop address and the
detector mode NORMAL, 2330 or 2312.
See Planning Instructions for the system
respectively for more information about the
modes and functions.
•
NORMAL
mode (analog): Detector
4300 is used in the systems EBL512
(SW version > 2.0) and EBL128, also as
a spare part for the detector 3316 in
NORMAL mode.
•
2330
mode (conventional): Detector
4300 is used in the systems EBL512 /
1000 / 2000 as the best substitute for the
detectors 2316 & 2317 + base 2330.
•
2312
mode (analog): Not used for 4300.
The different modes have different functions
and features, e.g. in the 2330 mode, the
detector does the fire judgement but in the
NORMAL mode this is done in the c.i.e.
The detector is prepared for an "Advanced
mode" to be used in conjunction with future
EBLxxx SW versions.
AI function
In the 2330 mode is the AI function used,
i.e.:
•
Combined heat and smoke sensing
will
guarantee reliable and accurate fire alarm
detection.
•
Variable delay function
, i.e. the delay
time before an alarm is influenced by
temporary temperature and/or smoke
obscuration changes.
