Bursting disks
Bursting disks are safety devices that protect a container from excess pressure. If a critical pressure
level is exceeded the disk bursts, the excess pressure is dissipated.
Bursting disks that have burst must be replaced.
Pressure relief dampers
Pressure relief dampers are installed in the exterior walls of buildings to dissipate the pressure
increase or drop that occurs when the system is activated.
Pressure relief dampers are closed in idle position. If there is an increase or drop in pressure over or
under a specified value the pressure relief dampers open and ensure that the pressure is relieved.
Check valve
Check valves permit the flow of extinguishing agent in the flow direction and prevent it in the
opposite direction. They are located at the transitions of the hoses to the manifold.
Pilot pressure relief device
The pilot pressure relief device dissipates a slow increase in pressure via a vent bore. Slow gas leaks
can occur, for example, if there are leaks in the extinguishing agent container. The pilot pressure
relief device closes automatically if there is an abrupt pressure increase through an activation, so
that the pilot line of the respective extinguishing zone is closed at flooding.
Manifold safety valve
Manifold safety valves are attached wherever dangers exist due to unreliably high pressure, e.g. at
distributors for multi-zone systems.
In the event of impermissibly high pressure the manifold safety valve ensures pressure compensa-
tion. The blow-off lines connected to the manifold safety valve safely dissipate the medium.
