1.3 FS2000
System
Operation
For FS2000 System operation, the Detector’s Fire and Fault signals are
sent digitally to the FS2000 System Controller using the four wire FS2000
FireBus. The FireBus provides the 24 Volts 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 SS2 Detector is connected to the FS2000
System using FireBus communication, the Controller
automatically
de-energizes the Detector’s Fault relay.
1.4 Overview
1.4.1
Model SS2 Detector Status Indications
The Model SS2 Multi-Spectrum Optical Fire/Flame Detectors are
microprocessor-based devices, which see ultraviolet (UV), visible (VIS),
and infrared (IR) spectral regions. The Detector's logic processor is
capable of quick response to fires while virtually eliminating false alarms.
The Model SS2 Detector has a 120° field-of-view.
There are two (2) LEDs on the Model SS2 Detector for indication of the
Detector status. During Normal Operation both LEDs will blink every 10
seconds.
If a Model SS2 Detector has a Fault, it
de-energizes
the Fault relay and
turns one (1) LED on. (The LED will not light if the Fault is a “No Power
Fault”). If the Fault condition, such as a “Low Voltage Fault”, is eliminated,
the Detector will automatically return to Normal Operation.
Faults caused by Excessive Input Voltage or temperatures outside the
operating temperature range require factory re-certification. Both LEDs
rapidly blinking (with frequency about 2 Hz) indicate faults requiring re-
certification.
If a Model SS2 Detector alarms to a fire, it
energizes
the Fire relay and
turns on both LEDs in the following sequence. One LED is turned on
immediately and the second LED will rapidly blink for several seconds
indicating that the Detector's FirePic is being permanently stored in the
Detector's solid-state memory. (FirePic is the several seconds of Detector
data, which precede an alarm event.)
1.4.2 Detection
Range
The detection range of the detector is 60 feet to an industrial standard of
one square foot gasoline pan fire within 5 seconds.
1.4.3 Field-of-View
The Detector incorporates a minimum 120-degree conical Field of View.
The fire emissions received by the Detector diminish at extreme edges of
