Communication channel
ƒ
A maximum of 2 communication modules, called COMn, can be connected in addi-
tion to the RS-485 on board the control unit. The communications setup menu then
includes three sections (n=1 ... 3) of parameters for setting the communication
ports.
ƒ
The RS485 port mounted as standard on the control unit is mapped as COM1, so any
additional channels will be named COM2 and COM3.
ƒ
The communication channels are completely independent, both from the hardware
point of view (physical interface type) and from the communication protocol point
of view.
ƒ
The communication channels can work simultaneously.
ƒ
Through appropriate programming (see parameter P17.n.09) FFL can act as Modbus
main pump, collecting the information of the other devices of the fire-fighting sys-
tem equipped with RS485 to coordinate them and send them to the alarm remote
control system.
10.1.8
Compliance with EN 12845
With the control unit set by default the operation complies with the EN12845 standard.
For this condition to be maintained, the following conditions must be met:
1. the automatic test must be disabled (P13.01 = OFF);
2. the motor detection started must come from the pick-up signal (P07.01 ≠ OFF and
P12.02 ≠ OFF);
3. the delayed automatic stop parameter must be disabled (P02.10 = OFF);
4. the input with the Enable automatic stop function must be disabled or the function
must not be combined with any input (as default);
5. the motor stop must be made exclusively through the Stop Magnet function com-
bined with a programmable output.
If any of the prescriptions are not respected, the writing EN12845 disappears from the
main page of the display.

Parameter programming
To access the parameter programming menu (setup):
1. set the switchgear in MAN mode (using the key selector SA1 - The red 'padlock' led
on the front lights up);
