Peer To Peer Networking

The basic control unit can be networked to other control units
and annunciators to provide additional relays, notification
appliances (bells) and LEDs. Up to 254 control units and
annunciators can be placed on the network. The network
is a DCLR loop layout. One control unit is designated the
‘master control unit’ for the network. Diagnostics can be done
at any control unit. Programming of an individual control unit
is done at that unit. Each control unit operates independently
