Minimum / Maximum sensor values

To find out how the environment is, where an analog detector 33xx /
430x / 440x in NORMAL mode is mounted, the minimum and
maximum sensor values can be studied. The sensor values are
continuously picked up and evaluated by EBL128 for each detector
individually. Every value is checked if it is a new minimum or
maximum value for that detector and if so, the value will be stored.
At midnight every day a memory will be updated and the new
minimum and maximum sensor values
or via EBLWin.
For analog smoke detectors the minimum and maximum sensor values
are shown as XX.X % (obscuration) per meter.
For analog heat detectors the values are shown as XX°C.
2-zone / 2-address dependence (Co-
incidence alarm)
In some premises 2-zone or 2-address dependent fire alarm ("Two unit
dependent" in EBLWin) can be used to avoid unwanted / false alarms
(nuisance alarms). A time channel can turn on/off this function.

2-zone dependence

Each zone in the system can be programmed to be "Two zone
dependent" for fire alarm activation. The zone has to belong to one of
ten "Two zone dependent" groups (1-10).
Function:
Two or more zones in the same group have to be in "fire alarm
101
state"
at the same time to activate fire alarm in the control unit.
When only one of the zones is in "fire alarm state" it is indicated in the
control unit (c.i.e.) as follows:
The buzzer sounds like for pre-warning (0.8 / 5 sec.).
In the c.i.e. LCD the following information is shown:
Co-incidence alarm zone ZZ
Programmable outputs can be activated by trigger condition "Two
Zone Dependent Fire Alarm" but no other outputs will be activated.
A co-incidence alarm can be manually reset ("Reset" button on the
front) and will be automatically reset 5 min. after it is no longer in
"fire alarm state" (i.e. below the fire alarm level).

I.e. the min. / max. sensor values are from the previous day.
