3309
Analogue heat detector. Enclosed (IP67)
detector has generated fire alarm. Terminals for remote indicator (RIL). Recess
for label holder (3391). The COM loop address is set with the Address setting tool
3314 / 4414. The Address setting tool 3314 is also used for mode setting:
NORMAL mode: 3309 is set in this mode in EBLWin to one of three algorithms
(static response temp. range) for class:
4300
Analogue multi detector. Discontinued and replaced by 4400 in normal mode, see
below. 4300 is a smoke detector and a heat detector within the same housing.
Scattered light (i.e. reflection of infrared light) is used to detect smoke and the heat
sensing element is a thermistor. The detector unit (actually the heat detector) can
detect a methylated spirits (alcohol) fire (EN54-9, test fire TF6; liquid fire), which
normally is impossible for a photo electric smoke detector to detect.
The detector has unleaded soldering.
To be plugged in an Analogue base (3312 / 4313 / 3379).
Built-in LEDs are lit to indicate that the detector
Prepared for mechanical lock (screw attached) – if required.
Via EBLWin, the mode of operation can be selected as follow:
a)
Zone-Addr.
001-01 (smoke)
001-02 (heat)
COM loop address
e.g. 123
b)
Zone-Addr.
001-01(smoke or
heat)
COM loop address
e.g. 123

This detector holds the ATEX classification: Ex II 3GD EEx nA II T5 (T 70°C), -20°C < Ta < 65°C.
50
i.e. the heat detector and/or the smoke detector.
51
The zone number has to be the same for both detectors. NOTE! When counting alarm points these "two detectors" are
regarded as two alarm points.
52
Adjusted smoke value = obscuration (%/m) x 10. Default heat alarm levels (50°C / 58°C) and smoke alarm offsets (50 / 58)
can be changed via EBLWin. The temperature cannot be lower than 0°C in the algorithm / graph.
A1 (54-65°C), min./typical/max. ambient temp. -20/+25/+50°C
A2 S (54-70°C), min./typical/max. ambient temp. -20/+25/+50°C
B S (69-85°C), min./typical/max. ambient temp. -20/+40/+65°C
A1 (54-65°C), min./typical/max. ambient temp. -20/+25/+50°C
A2 S (54-70°C), min./typical/max. ambient temp. -20/+25/+50°C
B S (69-85°C), min./typical/max. ambient temp. -20/+40/+65°C
Two presentation numbers (addresses): The detector unit works as two
separate detectors. The smoke detector is programmed for one zone-address
and the heat detector for another zone-address
e.g. the smoke detector during working hours and/or in control expressions for
programmable outputs).
One presentation number (address): The detector unit works as one
detector and is programmed for one zone-address.
If alternative b) is to work with "OR-functionality" or with a "Decision algorithm",
program this via EBLWin using either of these functionality options:
b1) OR-functionality: Either the heat detector or the smoke detector will
activate fire alarm. This alternative is recommended in most cases.
b2) Decision algorithm:
Fire alarm will be activated if:
Temperature (°C) + adjusted smoke value
Pre-warning will be activated if:
