Sensor value

An analog smoke detector is like a "sensor". It detects its environment
at all times. Each detected analog value is, in the detector, converted
to a digital "sensor value", which for each individual detector, is
continuously picked up and evaluated by EBL512 G3 United version
2.7.x. In Figure 17 the (digital) sensor values (during a certain time)
are represented by the graph "Working level".

Week average sensor value

Each hour, one sensor value is stored in a special memory (in EBL512
G3 United version 2.7.x) and each week, these stored sensor values
are used for a "week average sensor value" calculation.
done for each analog smoke detector individually. In Figure 17 the
(digital) week average sensor values (during a certain time) are
represented by the graph "
Each analog smoke detector has a default sensor value = 1 and a week
average sensor value = 1 (i.e. at Time = 0).
A "fire alarm offset" (value) is added to the week average sensor
value to get each detector's "Fire alarm level", i.e. the fire alarm level
will be adjusted in relation to each new week average sensor value in
order to keep the detector's fire alarm sensitivity constant. The fire
alarm level is in Figure 17 represented by the graph "
(C) - parallel with the graph "
In Figure 17 (at Time = 0):
The week average sensor value (B) is 1 (=0.1 %/m) and the fire alarm
offset is 3 %/m, i.e. the fire alarm level (C) is 0.1+3=3.1 %/m.
Service signal will be given when the week average sensor value for a
detector has reached the service signal level (1.8 %/m), i.e. the
detector is "dirty" and has to be replaced. See "
Figure 17. The week average sensor value will now stay on 1.8 %/m,

The week average sensor value will be calculated within 2 minutes after
any restart, i.e. also after SSD download. During these "2 min." all analog
smoke detector fire alarms are suppressed.
