Function: Two or more two-unit-dependent alarm points in the same
zone have to be in "fire alarm state" (i.e. over the fire alarm level)
the same time to activate fire alarm in EBL128. If only one such
alarm point is in "fire alarm state" it is indicated in EBL128 as a co-
incidence alarm:

The buzzer sounds 0.8 sec. each 5

In the display is the following text shown:
Co-incidence alarm detector ZZ/AA
Programmable outputs can be activated by the trigger condition "Two
Address 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).

Two-zone dependence (co-incidence alarm)

This function is valid only for the 4580 board zone line inputs. Two
specified zones must be in fire alarm state at the same time to activate
fire alarm in EBL128.
In some premises two-zone-dependent fire alarm (co-incidence alarm)
can be used to avoid unwanted false alarms (nuisance alarms).
NOTE! It is not recommended to use heat detectors and/or manual
call points in a zone with this function.
If only one two-zone-dependent zone is in "fire alarm state" it is
indicated in EBL128 as a co-incidence alarm:

The buzzer sounds 0.8 sec. each 5

In the display is the following text shown:
Co-incidence alarm zone ZZ
Programmable outputs can be activated by the 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".

Delayed alarm

In some premises delayed fire alarm activation can be used to avoid
unwanted false alarms (nuisance alarms). Note, this function is a
violation to the EN54-2 standard.
This function is valid only for the 4580 board zone line inputs.

A not two-unit dependent alarm point would in this state have activated a
fire alarm in EBL128.
