The number of EOL supervision boards are
limited to 16 per channel as the boards are
polled more frequently than the loudspeaker
supervision boards to comply to the standards
for emergency sound systems.
•
The multi channel interface can have up to 16
supervision boards connected to each basic amplifier
channel of the multi channel interface. The
maximum number of boards in total across all
