To ensure that the building is sealed off internally in case of fire, it is often necessary to close other fire dampers when
one fire damper is released. Release groups are defined for this purpose.
Fire dampers can additionally be activated by smoke detectors in order to comply with the building code requirements
for the cold smoke safety of ventilation and air conditioning systems. Depending on the requirement, this is performed
either in a decentralised manner on the fire dampers and/or centrally using a fire detection system. Within Wildebo-
er-Net volume flow and pressure controllers can additionally contribute to cold smoke safety (VDI 6010) by carrying
out a passive alarm function as passive devices in release groups. These controllers cannot release the group. The
release of a group must always be acknowledged with the Wildeboer-Net software.
Release groups are parametrised by the Wildeboer-Net software and transferred to the field modules in the form of
release group matrices. In the process, the field devices connected to the field modules can always be included as
devices in one or multiple release groups.
The field modules monitor each other mutually within a release group. For this purpose each field module must receive
what is referred to as a "heart beat signal" (sign of life) from every other field module within a certain time interval. If
this "heart beat signal" is not received for a longer period, the devices in the affected group automatically assume their
safe status. In the case of fire dampers this is the CLOSED position. The safe status of other field modules depends
on the respective parametrisation. Possible causes for the missing signal include, for example, power failure on a
field module or a bus interruption.
Release group controls in Wildeboer-Net are restricted to the field level of a subnet controller. Release groups can
be connected universally for all subnet controllers using additional on-site fire detection system couplers or by inte-
grating fire detection panel modules or I/O modules. The use of FACP modules is recommended due to the existing
line monitoring.

This way, it is possible to comply with the cold smoke safety requirements of MBO.
