Siemens FS-RU2 Installation Instructions & User Manual

INSTALLATION INSTRUCTIONS
Model FS-RU2 Serial Relay Unit
Model FS-RE8 Serial Relay Extender
The FS-RU2 Serial Relay Unit is an optional accessory for the FS-250 and FS-250C Fire Alarm System
Control Panels. The FS-RU2 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.
