11.3.5 NETPG5 OPTIONS
1. Ack broadcasts to specific SID
If this parameter is set to a non-zero SID number XYZ then this panel will send an
acknowledge to a broadcast sent by SID XYZ. If this parameter is set to zero then this
feature is disabled.
Only one device on a network (say SID XYZ), should be programmed to acknowledge all
broadcasts but it can have its own broadcasts acknowledged if another panel on the network
has "ACK broadcasts to specific SID" set to XYZ.
