Stand-Alone Operation

For Stand-Alone operation, the Detector may be connected to a FM Approved or
UL listed Fire/Security Panel. The Detector operated in the Stand-Alone mode,
uses the Fire, Fault, and Verify (optional) relays or optional 4 to 20 mA current
source (FSC Model MA420-4 Module, refer to Section 4.3) to interface with the
Fire/Security Panels. For Stand-Alone operation, the Detector's Fault relay is
automatically configured by the on-board microprocessor. The input current of
the Detector is about 15 mA higher in the Stand-Alone mode compared to

FS2000 System operation.

NOTE: The Fault relay is not available when the Detector is wired to
the FS2000 System.
FS2000 System Operation
For FS2000 System operation, the Model SS4-AS/-AS2 Fire and Fault signals
are sent digitally to the FS2000 System Controller using the four wire FS2000
FireBus. The FireBus provides 24 Volt DC power for the Detector and RS-485
digital communication (Refer to Honeywell Analytics document MN0003:
"FS2000 FIRE EARLY WARNING SYSTEM - INSTALLATION and
OPERATIONS GUIDE"). For special remote alarm applications, users may also
connect directly to the Detector's Fire alarm relay.
NOTE: When the Model SS4-AS/-AS2 Detector is connected to
the FS2000 System using FireBus communication, the Controller
automatically disables the Detector's Fault relay.
