INSTALLATION INSTRUCTIONS
Model FS-RU Serial Relay Unit
Model FS-RE8 Serial Relay Extender
The FS-SAU Serial Relay Unit is an optional accessory for the FS-100 Fire Alarm System Control Unit. The
FS-SAU includes a processor board and a relay board. The processor board receives commands from the
control unit for activating the relays and transmits supervision and control functions to the control unit. The
processor board can control up to 3 relay boards. Each relay board provides 8 relays with form C contacts.
The control unit can address up to 8 Serial Relay Units and/or Serial Annunciator Units. Auxiliary power
supplies will be required to power units beyond the control unit capability.
