Diagram times and functions
Time 4 Start of release time (FZ)
If the emergency stop zone has not been activated before the end of the evacuation time, this
time is identical with 3; otherwise the release time starts at the end of the emergency stop
activation. The relay and the tank valves are activated at the start of the release time. As the
release time is started only when the emergency stop zone is not active, the emergency stop
valve is also activated.
In systems with a main and spare battery the detector zone input No. 7 (which must be
programmed for special functionality) decides whether the pilot valve (spare zone inactive) or
the spare valve (spare zone activated) is to be activated.
Time 4a End of the switch-off delay time for a pressure relief flap (DE)
When the switch-off delay time has expired, the corresponding output for the pressure relief
flap (DE) is inactive again.
Time 5 End of the release time (FZ), start of the residual releasing time (RFZ)
When the release time ends, the residual releasing time is started. All outputs/valves for the
release (tank valve, pilot or spare valve, emergency stop valve) are closed again.
Time 6 End of residual releasing time (RFZ)
The pre-control valves (VV) are closed.
Time 7 Activation of the extra releasing zone/extra releasing time (NFZ) is started
The relay and the tank valves are opened at the start of the extra releasing time. The
emergency stop valve (NSV) is also activated.
In systems with a main and spare battery the detector zone input No. 7 (which must be
programmed for special functionality) decides whether the pilot valve (spare zone inactive) or
the spare valve (spare zone activated) is to be activated.
End of the delay time of a pressure relief flap.
The delay time of a pressure relief flap has expired, the corresponding output is activated and
the associated switch-off delay time is started.
Time 8 End of the extra releasing time (NFZ), start of the residual releasing time (RFZ)
When the extra releasing time ends, the residual releasing time is started. All valve
activations required for the release, e.g. for the tank, pilot, spare and emergency stop valves,
are reversed.
Time 8a End of the switch-off delay time of a pressure relief flap.
The activation of the pressure relief valve (DE) is reversed when the switch-off delay time
expires. The pressure relief valve is closed.
Time 9 End of residual release time (RFZ)
Activation of the pre-control valves is reversed at the end of the residual releasing time. The
pre-control valves are closed.
Time 10 Reset the fire alarms (1st/2nd alarm)
All detector zones with the alarm criterion Fire are reset.
The pre-alarm and evacuation alarm are stopped, the associated outputs are no longer
activated.
The area valve and the switchover valves (inverse activation) are no longer activated.
