Panasonic 4301 Specification Sheet

•
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
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
respectively for more information about the
modes and functions.
•
NORMAL mode (analog):
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):
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.
