FS-100 Installation & Operation Manual
MINIMUM CONTROL UNIT CONFIGURATION
Power Supply
A 3A, 24V nominal power supply provides all operating power to the control unit for both standby and
alarm conditions. Sufficient battery charging capability is available to charge sealed lead-acid batteries
within code requirements for 60 hour quiescent plus 5 minutes alarm. The cabinet will hold batteries only
up to 7 AH. The back-up battery is 24V, maintained by floating on the power supply. The power supply is
physically contiguous with the main board.
Addressable Device Circuit
The FS-100 control unit has one addressable device circuit that is programmed for connection to
Siemens addressable devices. The addressable device circuit drives up to 60 addressable initiating
devices, detectors and/or modules. Each detector and module can support one output device.
Notification Appliance Circuits
The FS-100 control unit has four independent notification appliance circuits (NACs). Each circuit can be
selected to give continuous output or one of eight sounding patterns available in the control unit. There is
also a system coder capable of zone coded operation. All of the NACs are power limited and can be
wired for Class A (Style Z) or Class B (Style Y) operation.
RS485 Communications Circuit
The FS-100 control unit has an RS-485 Communications Circuit that will drive up to 16 remote LCD
annunciators and 8 Serial Relay Units and Serial Annunciator Units on the RS485 communication line.
Status Relays
Three dry relay contacts are provided. These contacts are dedicated to alarm, trouble and supervisory
indications. The relay contacts are form C and are rated 1A @ 28VDC resistive.
OPTIONAL CONTROL UNIT CONFIGURATION
A maximum control unit configuration can include all of the minimum configuration items plus additions as
noted below. Details of these accessories are given in Appendix D.
Municipal Tie Board
The Siemens Model FS-MT municipal tie board provides local energy and polarity reversal connections.
The polarity reversal connections provide a trouble circuit and an alarm circuit with optional trouble
output.
RS232 Communication Board
The Siemens Model FS-232 RS-232 communication board will allow event data to a serial printer or
terminal.
DACT Board
The Siemens Model FS-DACT Digital Alarm Communication Transmitter board will send control unit
status data to a remote receiving station.
