Ssas Alert Unit - Furuno IC-307 Operator's Manual

2.2.2 SSAS alert unit

Three SSAS alert units can be connected. For wiring, see the illustrations below and the
interconnection diagram at the back of this manual. For the terminal unit (FELCOM 15/18)
and the communication unit (FELCOM 16/19), the wiring of the SSAS is monitored and if in
error "TROUBLE: SSAS UNIT connection abnormality." is displayed. Further the ERROR
lamp (FELCOM 16) flashes.
Connect wiring to the terminal board 16P0229 inside the SSAS alert unit. To differentiate
between units in case of multiple unit installation, change jumper block settings as shown
below, in accordance with how many units are installed.
