See Fig. 9.13 for exemplary connection of the PK1 relay output (performing the fP1 function) used to
control an electro-valve or other device triggering the fire extinguishing agent discharge during the
automatic fire extinguishing procedure. The connection diagram for PK2 and PK3 outputs is analogous.
In order to separate the measurement voltage - 5 V from the supply voltage + 24 V, electro-valves
should be installed in the line through a serially connected rectifying diode of applicable power in
relation to the load.

See Fig. 9.14 and 9.15 for exemplary connections of the PK4 and PK5 relay outputs used to control fire
alarming devices, e.g. acoustic signalling devices or warning diodes. The connection diagram for PK6 and
PK7 outputs is analogous.
