FS-100 Installation & Operation Manual
BATTERY SETS
The FS-100 control unit is designed to use only sealed lead-acid or equivalent batteries for back-up
power. The system enclosure can house 7 AH, 24VDC battery sets, Model BT-33.
AUXILIARY MODULES
Remote LCD Annunciator
The Siemens FS-RD remote LCD annunciator consists of a backlit 80 character LCD alphanumeric
display, 4 menu buttons, 4 dedicated buttons for operator interaction, 6 LED indicators, and a security
key-switch. The display and controls on the annunciator are the same as those on the front of the control
unit, including a key-switch for security. The back light operates only when the data are being accessed,
to conserve power.
Up to sixteen annunciators may be addressed by the communications circuit, but some may require
auxiliary power supplies, depending on the total accessory power loading.
Serial Relay Unit and Serial Relay Extender
The Siemens FS-RU 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 FS-RE8 relay boards. Each relay board
provides 8 relays with form C contacts. The control unit can address up to 8 FS-RU Serial Relay Units
and/or FS-SAU Serial Annunciator Units. Auxiliary power supplies will be required to power units beyond
the control unit capability.
Serial Annunciator Unit and Serial Annunciator Extender
The Siemens FS-SAU includes a processor board and an annunciator driver board. The processor board
receives commands from the control unit for activating the outputs and transmits supervision and control
functions to the control unit.
The processor board can control up to 4 FS-SAE16 annunciator driver
boards. Each driver board provides 16 supervised outputs for LEDs or incandescent lamps. The control
unit can address up to 8 FS-RU Serial Relay Units and/or FS-SAU Serial Annunciator Units. Auxiliary
power supplies will be required to power units beyond the control unit capability.
ADDRESSABLE DEVICES
Siemens Addressable Detectors
The control unit processor sends the sensitivity and pre-alarm settings to the detectors and polls the
detectors as to their status. The detector determines normal, trouble, pre-alarm or alarm conditions and
relays the status to the control unit.
Variable Thresholds
The obscuration level for alarm can be adjusted from the control unit on a permanent or time-variable
basis.
This facility also means that the control unit can display information on individual points for
maintenance or service.
