9.3.3 fK3 EXTINGUISHING STOP function
The EXTINGUISHING STOP function is executed in connection with the monitoring line no. 3 used to
supervise and transmit the signal for manual stopping the fire extinguishing process from external
EXTINGUISHING STOP push buttons. One push button (or more push buttons in parallel) may be
connected to a monitoring line. See fig 9.4 for the monitoring line circuit with one PW-61 "fire
extinguishing stop” push button. A LED shows the operation of the line and push buttons while pressing
them.
After the push button is pressed:
-
the automatic fire extinguishing procedure is suspended;
-
this condition is indicated by the EXTINGUISHING STOP diode on the control panel front panel,
in the EXTINGUISHING ZONES field;
-
the control panel acoustic signalling is switched on provided it has been silenced;
-
the relay output performing the fP12 functions is activated if the relay is assigned to transfer
information regarding the suspension devices actuation.
One of the two following suspension algorithms may be selected in the control panel menu:
Algorithm 1:
Pressing the EXTINGUISHING STOP push button results in disablement of the fire extinguishing signal
and stopping the evacuation time countdown. Releasing the EXTINGUISHING STOP push button results
in starting the programmed evacuation time countdown from the beginning.
Algorithm 2:
Pressing the EXTINGUISHING STOP push button results in disablement of the fire extinguishing signal but
it does not stop the extinguishing agent discharge delay time countdown (evacuation time). Releasing
the EXTINGUISHING STOP push button results in immediate sending a fire extinguishing signal to the fire
extinguishing agent discharge devices (if the delay time elapsed when the push button was pressed). In
case the push button is released before the set delay (evacuation) time elapses, the fire extinguishing
signal is sent after the countdown is completed.

9.3.4 fK4 EXTINGUISHING BLOCKADE function
The EXTINGUISHING BLOCKADE function is performed in connection with the monitoring line no. 4 used
to supervise and transmit the signal for fire extinguishing blockade from an external push button. One
push button (or more push buttons in parallel) may be connected to a monitoring line. See Fig 9.5 for
the monitoring line circuit with one PB-61 push button. A LED in the monitoring line circuit indicates
actuation of the fire extinguishing blocking function and circuit operation.
Switching the system into the blockade mode by means of the push button installed in the monitoring
line or the push button in the control panel results in:
