Smoke detection and triggering devices for fire dampers or smoke dampers

Smoke detection and triggering devices are used for controlling and triggering fire and smoke dampers in air ducts of HVAC systems. Following smoke detection and the corresponding signalling, the fire or smoke dampers are triggered to shut through the interruption of the supply voltage. The spread of smoke in buildings via the air ducts is contained or prevented.

Regulatory framework

In this work area, DIBt grants national technical approvals (abZ)/general construction technique permits (aBG). The smoke detection and triggering devices are verified for use in ducts with air velocities of between 1 m/s and 20 m/s.

Please also refer to the relevant provisions of the federal states following MVV TB 2020/1, Sections B and and the Model Guideline on fire protection requirements for ventilation systems (M-LüAR).
