General
The analog heat detector 3309 measures the 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.
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.
3314 is also used to set the detector mode.
•NORMAL mode (analog): Used in the 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.
•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).
•2312 mode: Not used for 3309.
Algorithms
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 3309 in NORMAL mode.
ATEX classification
3309 complies with the ATEX classification Ex II 3GD EEx nA II T5.
Waterproof
The thermistor, the LED, all electronics, etc. is mounted in a waterproof detector housing, mounted on a connection box.
Label holder
A label holder, intended for a label showing
Miscellaneous
The COM loop is connected to the detector, which is provided with three pairs of flying leads with female
Product applications
Used in the systems EBL512 / 128 / 1000 / 2000.
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.
