Make sure that the maximum number of EOL and Loudspeaker Supervision boards is not exceeded.

•PRS-1P500 can have a maximum of 80 boards, of which 16 can be LBB4443/00 EOL boards or LBB4441/00 with line supervision enabled.

•PRS-2P250 can have a maximum of 40 boards per channel, of which 16 can be LBB4443/00 EOL boards or LBB4441/00 with line supervision enabled.

•PRS-4P125 can have a maximum of 20 boards per channel, of which 16 can be LBB4443/00 EOL boards or LBB4441/00 with line supervision enabled.

Note

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 channels is 80, of which 64 can be LBB4443/00 EOL boards or LBB4441/00 with line supervision enabled. Do not to exceed the maximum number of supervision boards related to the maximum output power of the amplifier channel; see section 12.6.5.
