contact. In this system, both line faults and opening a contact is indicated with a common message as a
pressure/mass monitoring line fault.
A larger number of normally-open and normally-closed (in series) K monitoring contacts may be
connected to the monitoring line.

9.3.8 fK8 EXTERNAL ALARM INPUT function
The function may be executed using monitoring lines no. 1 ÷ 11. Line no. 8 is recommended for receiving
the alarm signal. See Fig. 9.9 for a typical connection diagram. When the K contact is closed, a signal is
transmitted to the control panel and a fire extinguishing procedure is actuated, provided the fire
extinguishing zone has not been switched into the (only) manual control mode. The actuation signal is
treated as a signal emitted from an automatic source. The K contact may be an alarm relay contact from
a different fire signalling control panel.
A larger number of K contacts may be connected in parallel to one monitoring line.
