the automatic fire extinguishing procedure is initiated;
the actuation state is signalled by the EXTINGUISHING START diode switching on;
acoustic signalling of the control panel and proper relay outputs performing the fP4, fP5, fP7, fP13
functions is activated;
after the programmed delay time elapses, the fire extinguishing agent outflow signal (actuation of relays
performing the fP1, fP2, fP6, fP14 functions) is emitted.
Fig. 9.2 Monitoring line circuit to perform EXTINGUISHING START function
9.3.2 fK2 RESERVE START function
The RESERVE START function is executed in connection with the monitoring line no. 2 used to supervise
and transmit the signal for actuation of additional supply of the fire extinguishing agent from external
PD-61 FIRE "RESERVE START" push buttons. One push button (or more push buttons in parallel) may be
connected to a monitoring line. See Fig. 9.3 for a monitoring line circuit with one push button. A LED
shows the operation of the line and push buttons while pressing them.
After the push button is pressed:
-
additional supply of a fire extinguishing agent is actuated provided the control panel is in the
discharge condition, i.e. the main supply of the fire extinguishing agent has been depleted and
the alarm is not cancelled;
-
the relay performing the fP3 functions is activated;
-
the red RESERVE START diode is lit in the control panel area field.
