Figure 24 Decision Algorithm Graph.
When the calculated value in the decision algorithm exceeds the lower graph, pre-
warning will be activated. When it exceeds the upper graph, fire alarm will be
activated.
Temperature = °C. Smoke value = obscuration (%/m) x 10.
The technical address is set with an Address setting tool 3314 / 4414. The detector
has an address label on which the programmed technical address is to be written.
Note: The multi detector 4300 in system FT128 takes two COM loop (technical)
addresses of the available 255 addresses. One address that is set with the 3314 / 4414
tool but also the following address will be "occupied" for the heat part of the detector and
cannot be used by any other unit on the COM loop.
The Address setting tool 3314 / 4414 is also used for mode setting:
NORMAL mode: 4300 is set to this mode in EBLWin. For the smoke detector, set
to one of six algorithms H-15, H-35, L-15, L-35, N-15 or N-35 and for the heat
detector set to one of three algorithms for class A1 (static response temp. 54-
65°C), A2 S (54-70°C) or B S (69-85°C).
4301 Analogue photo electric smoke detector. Discontinued and replaced with 4401
in Normal mode, see below. Scattered light (i.e. reflection of infrared light)
is used to detect smoke. To be plugged in an Analogue base (3312 / 4313 /
3379). Built-in LEDs are lit to indicate that the detector has activated fire alarm.
Prepared for mechanical lock (screw attached) – if required.

4400 Analogue multi detector. Replaces 4300 in Normal mode, see above. 4400 is a
smoke detector and a heat detector in one housing. Scattered light (i.e. reflection
of infrared light) is used to detect smoke and the heat sensing element is a
thermistor. To be plugged in an Analogue base (3312 / 4313 / 3379). Built-in LEDs
are blinking to indicate that the detector
has activated fire alarm. Prepared for
I.e. the heat detector and/or the smoke detector.
