TECHNICAL DESCRIPTION
1.1 Features and Specifications
1.1.1 General Description
The Model SS4-AS/-AS2 Multi-Spectrum Electro-Optical Fire/Flame Detectors are
fast-reacting (within 5 seconds), digital, configurable, microprocessor-based,
“smart” units. This Detector has sensitivity to Type A, B, and C flaming fires. They
are optimized for detection of hydrogen, ethanol, methanol, and methane (natural
gas) fires. Detectors of this design process Ultraviolet (UV), Wide Band Infrared
(IR), and Visible (VIS) spectral ranges from ruggedized Solar-blind UV, “Quantum-
Effect” IR, and Visible (VIS) sensors correspondingly. They are equipped with
SRL-BIT (Built In Test) for optical “through the lens” of both the sensors and lens.
These UV, IR, and VIS Fire Detectors have false alarm immunity, and alarm range
between 15 and 60 feet for a one square foot heptane, gasoline, kerosene, or
isopropyl alcohol pan flame with a 120-degree (±60 degrees from the axis)
conical field of view. Additional optimization for hydrogen assures a less than 5
second response to a 10-inch hydrogen flame at 15 ft.. Their microprocessor-
based algorithms (FirePic, SnapShot, and Tri-Mode Plot) assure time
programmable alarm verification, Fire Signature Analysis, and compatibility with
standard FM Approved or UL Listed fire alarm panels.
The Detector has the flexibility to be re-configured in the field. Its installation is
simple, and operation straightforward due to the built-in self-testing feature.
Therefore, the maintenance consists mainly in keeping the Detector window lens
clean, and performing periodic testing required by the manufacturer of the Fire
Control and Suppression System.

1.1.2 Applications
Applications of the Model SS4-AS/-AS2 Detectors include storage warehouses of
Ethanol, Methanol, and Methane (Natural Gas) and Hydrogen gas, among others.
1.1.3 Detector Locations
For unobstructed performance, considering Detector locations in application
areas, avoid sources, other than fire, which may cause false alarms, such as
operations utilizing welding or gas torch equipment, high power sources of EMI
or RFI, or artificial lighting pointed directly at the Detector. Locations experiencing
strong mechanical or acoustical vibrations should also be avoided. For optimum
performance, locate the Detector(s) as close as possible to the potential fire
source, preferably, along the axis of the vision cone. Install enough Detectors to
completely eclipse the fire hazardous area. Assure accessibility for the Detector
lens cleaning, as well as best possible protection and/or cleaning from fog, rain,
ice, dust, hazardous atmospheres, and other adverse elements. If necessary,
utilize the Steel Swivel Mount (Model SM2) or 316 Stainless Steel Swivel Mount
(Model SM4) for greater flexibility in mounting locations (See Figures 4 and 5).

1.2 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.
1.3 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.
