It is the life safety and security management, 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.
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.
The configurable Desigo room automation does not support emergency lighting control with service and test
functions for decentralized or centralized batteries.
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.
