2-zone / 2-address dependence (Co-
incidence alarm)
In some premises 2-zone or 2-address dependent fire alarm ("Two unit
dependent" in WinG3) 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 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:
