than for fire alarm, i.e. pre-warning will be activated before the
fire alarm from the same alarm point.
3. heavy smoke alarm will be activated at a higher level (bigger
offset) than for fire alarm, i.e. heavy smoke alarm will be
activated later than the fire alarm from the same alarm point.
The pre-warning offset and the heavy smoke alarm level can, for the
whole system, be set in Win512 version 2.7.x, see chapter "Alarm
algorithms", page 137.
The fire alarm offset can, for the whole system, be set in Win512
version 2.7.x, see chapter "Alarm algorithms", page 137.
NOTE! This is not a normal action and a special password is required.
"Pre-warning", "Fire Alarm" and "Heavy Smoke Alarm" can activate
programmable outputs respectively, see chapter "Control expression",
page 71.

Alarm algorithm / Alternative alarm algorithm
In order to reduce the nuisance alarms
alarms will be activated, six different alarm algorithms are available.
See Figure 18., page 87. They are based on:
Normal (N), High (H) or Low (L) sensitivity
Normal (15 sec.) or slow (35 sec.) detection time
Normal sensitivity (Default) Fire alarm offset is 3.0 % smoke
obscuration per meter.
High sensitivity Fire alarm offset is 2.4 % smoke obscuration per
meter, i.e. less than for normal sensitivity. Can be used when an
"early" fire alarm is wanted.
Low sensitivity Fire alarm offset is 3.6 % smoke obscuration per
meter, i.e. more than for normal sensitivity. Can be used to reduce
