General
Algorithms
The analog heat detector 3309 measures the
EBL512 / EBL128 use algorithms for class
A1, A2 S and B S, according to EN54-
5:2000, for fire alarm detection. Via Win512
/ Win128 is an algorithm selected for each

temperature through a thermistor.
The
temperature range is 0°C to 100°C in steps
of 0.5°C. The detector has an LED that will
light up when the detector goes into alarm.
The detector also has an output for an
external LED, e.g. 2218.
ATEX classification
3309 complies with the ATEX classification
Ex II 3GD EEx nA II T5.
Programming/Compatibility
The address setting tool 3314 is used to set
the detector's COM loop address. The
detector has an address label inside, where
the address is to be written.
Waterproof
The thermistor, the LED, all electronics, etc.
is mounted in a waterproof detector housing,
mounted on a connection box.
3314 is also used to set the detector mode.
• NORMAL mode (analog): Used in the
Label holder
A label holder, intended for a label showing
"zone-address" or "technical number", can
be mounted in the connection box.
system EBL512 (SW version >2.0) and
EBL128.
The detector works as a
temperature sensor where the analog
readings (0°C to 100°C) are converted to
digital "sensor values" that are read and
evaluated by the c.i.e. Algorithms for
class A1, A2 S or B S (set in Win512).
When the class A1 or A2 S algorithm is
used, 3309 is a spare part for detector
2340 and when the class B S algorithm is
used, 3309 is a spare part for 2341.
Miscellaneous
The COM loop is connected to the detector,
which is provided with three pairs of flying
leads with female push-on connectors.
Product applications
Used in the systems EBL512 / 128 / 1000 /
2000.
• 2330 mode (conventional): Used in the
systems EBL512 / 1000 / 2000 as an
equivalent to the enclosed addressable
fixed temperature heat detector 2340
(60°C), i.e. as a class A2 S heat detector
(static response temperature 57°C).
Heat detectors are normally used where
smoke detectors can not be used or in rooms
where the temperature can be expected to
rise rapidly in case of a fire.
The detector is intended for outdoor use
(must not be exposed to heavy sunlight) or
in high humidity indoor premises.
• 2312 mode: Not used for 3309.
