Bosch FAS‑420‑TP Series - Scope of Delivery: Smoke Aspiration System

Bosch Sicherheitssysteme GmbH Operation guide 2020.04 | 6.1 | F.01U.029.275
In normal operation, the steam and gas mixtures flow in any direction through the safety
barrier. An ignition of the mixture in the upstream aspirating smoke detector will cause the
developing detonation to be arrested. Ignition is prevented by the flame filter. Combustion of
the mixture in the flame filters may cause a rebound of the detonation front. To prevent this, a
minimum pipe length of 1.0m between the installation point of the detonation safety barrier
and a possible ignition source (aspirating smoke detector) must be maintained. Permanent
fire prevention is thus achieved indirectly.
!
Caution!
The connecting pipe between the aspirating smoke detector and the detonation safety barrier
must be made of metal. During installation, care must be taken to ensure that the threaded
connections are bolted together gas-tight using synthesol or sealing tape.
