2-address (-unit) dependence

Each analog detector, addressable multi purpose I/O unit (3361)
monitored Input 0 (Z) and 8 zones expansion board (4580) input, can
be programmed for 2-unit dependent fire alarm activation. (Heat
detectors should not and manual call points must not be 2-unit
dependent).
Function:
Two or more units in the same zone have to be in "fire alarm state"
at the same time to activate a fire alarm in the control unit. When only
one unit 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.).

If, during these 5 minutes, at least one more unit (in the zone) or at

Co-incidence alarm ends and normal fire alarms will be activated in
