Fire alarm systems
Analog photoelectric
smoke detector
4301
•
Constant sensitivity / Service signal at a fixed level of contamination
•
New advanced algorithms and functions and yet compatible with older EBL systems
General
The photoelectric (optical) smoke detector
has a low profile design,
unleaded
soldering
and the latest IC technology,
which will secure the highest reliability
possible. In the 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 but it also causes steam, fog, etc. to
condense into moisture on its surfaces, to
prevent false (nuisance) alarms.
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
4301 is used in the systems EBL512
(SW version > 2.0) and EBL128, also as
a spare part for the detector 3304 in
NORMAL mode.
•
2330
mode (conventional): Detector
4301 is used in the systems EBL512/
1000/2000 as a spare part for the
detector 3304 in 2330 mode.
•
2312
mode (analog): Detector 4301 is
used in the systems EBL512/1000/2000
as a spare part for the detector 3304 in
2312 mode.
The different modes have different functions
and features, e.g. in the 2330 mode, the
detector does the fire judgement but in the
NORMAL and 2312 modes 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.:
•
Variable delay function
, i.e. the delay
time before an alarm is influenced by
temporary smoke obscuration changes.
