Panasonic Smoke Alarm 4301 User Manual

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  
Address / Detector mode  
The photoelectric (optical) smoke detector  
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.  
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.  
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.  
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.  
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.
