19.3.3.3 Parameters for Combined Decision Algorithm
Valid for the detectors 4300 / 4400. All in NORMAL mode.
Offset, see "Parameters for Smoke Algorithms" above. Level, see "Parameters for Heat
Algorithms" above. See also “4300” page 53.
The following example is for the Dec algorithm for the 4300 detector.
 Offset, pre-warning: Offset value, default 50 (5.0%/m).
 Offset, alarm: Offset value, default 58 (5.8%/m).
 Level, pre-warning: Level, default 50 (°C)
 Level, alarm: Level, default 58 (°C).
Note: Changing these parameters will affect the sensitivity and detection time and should
be done by authorised personnel only! In addition, a special password is required to
change the fire alarm parameters.

In the list shown in Figure 53 above, Steady (continuously) and Intermittent 0.8 / 0.8 s are
already defined since these alternatives are often used. It is however, possible to define
them to something else.
User defined 1-8 have to be defined individually:
Name: Normally changed to something that describes the output signal (e.g. "Steady") or
what it is meant for (e.g. "Alarm devices").
Type: Steady / continuous (default)
Intermittent
