24.2 Automation station for emergency controls for
HVAC, light, and blinds
The DXR2 for emergency control, receives emergency signals (e.g. fire or
evacuation) via digital inputs and takes over control of the electrical and
mechanical installations for light, facade, and HVAC in a the building as long as
the various supply and room automation components remain undamaged.
It is the Danger management system, and not Desigo room automation, that is
responsible for fire detection and evaluation of the correct HVAC emergency
operating modes for a fire section and primary plants.
WARNING
Desigo TRA is not approved by fire authorities. Fire can result in
death or
serious injury.
As a consequence, TRA fire solutions are only used on non-critical
applications with a limited risk to health and risks,
For critical application, an individual permit by the fire authorities on site must
be acquired for a specific project.
The configurable Desigo room automation can switch all available luminaires to
a specified value at the highest priority during an emergency. This is not
emergency lighting or evacuation route control, but rather is only a supporting
measure during an emergency to supply all rooms with the maximum
brightness.
NOTICE
The configurable Desigo room automation does not support emergency
lighting control with service and test functions for decentralized or
centralized batteries.
The function is part of application types for central functions and can be loaded
to a DXR2.E/M18.
