APPROVALS
The Model SS4-AUV/-AUV2 Ultraviolet Fire Detectors have been manufactured in compliance with the
requirements of the ISO-9002 standard and have been approved by:
• F ac tory Mutual (FM) for the United States

SECTION 1
TECHNICAL DESCRIPTION
1.1 Features and Specifications
1.1.1 General Descriptio n
The Model SS4-AUV/-AUV2 Ultraviolet Fire/Flame Detectors are fast-r eacting (within 5 seconds), digi tal,
configurable, computerized, “sm ar t” units. They are capable of solar-blind flame detecti on in the ultra-violet
spectral range (185 to 260 nanometers) utilizing long-life twin ruggederized UV sensors. They are
equipped with SRL-BIT (Built In Test) for optical “through the lens” of both the sensors and lens. The
Model SS4-AUV/-AUV2 Ultraviolet Fire Detect or has sensitivity to Type A, B, and C flaming fires, false
alarm immunity, and an alarm range between 15 and 60 ft. to a one square foot gasoline pan fi re, with a
120-degree (± 60 degrees from the axis) conical field of view. Their microprocessor-based algorithms
(FirePic, SnapS hot, and Tri-Mode Plot) assure tim e programmable alarm verification, Fi re Signature
Analysis, and compatibility with standard approved fire alarm panels.
The Detector also has the flexibilit y to be re-configured i n the f iel d. It s i nstall ation i s sim ple, and operati on
straightforward due to the built-in self-testing feature. Therefore, the maintenance consists mainly in
keeping the Detec tor window lens clean, and performing periodi c testing requi red by the manufacturer of
the Fire Control and Suppression System . The SS4-AUV/ SS4-AUV2 are UV only det ectors and are f or
indoor applications where UV noise sources, such as weldi ng, are not present.

1.1.4 Detector Location s
For unobstructed perf ormance, considering Det ector locations in application ar eas, avoid sources, other
than fire, which may cause fal se alarm s, such as oper ati ons uti li zing weldi ng or gas torch eq ui pm ent, hi gh
power sources of EMI or RFI , or artifici al lighting poi nted directly at the Detector . Locations experi encing
strong mechani cal or acoustical vibrations should al so be avoided. For optimum performance, l ocate the
Detector(s) as close as possi ble to the potenti al fire source, preferabl y, 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, an d other adv erse elem ents. If necessary, uti lize t he Steel Swivel Mount (Model
SM2) or 316 Stai nless Steel Swivel Mount (Model SM4) for gr eater flexibility in m ounting locations (See
Figures 4 and 5).
1.2 Stand-Alone Operation
For Stand-Alone operation, the Model SS4-A/-A2 Detector may be connected to a suitably approved
transmitt er or control system/panel . T he Detector operat ed in the Stand-Alone mode, uses the Fire, Fault ,
and Verify ( optional) relays or opti onal 4 to 20 mA c urrent source (FSC Model M A420-4 Module, ref er to
Section 4. 3) to interface to F M A ppr ov ed or UL listed Fire /S ec uri ty Panels. For Stand-A lone operation, the
Detector's Fault relay is automatically configured by its on-board microprocessor. The input c ur r ent of the
Model SS4-AUV/-AUV2 Detector is about 15 m A higher in the Stand-Alone mode c om pared to FS2000
System operati on.
NOTE: The Fault relay is not available when the Detector is wired to the FS2000 System.
1.3 FS2000 System Operation
For FS2000 System operat ion, the Model SS4-AUV/-AUV2 Fire and Fault signal s are sent digitally to the
FS2000 System Contr oller using the four wire FS2000 FireBus. The Fi reBus pr ovides 24 Volt DC power
for the Detector and RS-485 digital communication (Refer to Fire Sentry document MN0003: "FS2000
FIRE EARLY WARNING SYSTEM - INSTALLATION and OPERATIONS G UIDE"). For special rem ot e
alarm applic ations, users may also connect directly to the Detec tor’s Fire alarm relay.
NOTE: When the Model SS4-AUV/-AUV2 Detector is connected t o the FS2000 System using FireBus
communicati on, t he Controller automatically disables the Detector’s Fault relay.

1.4 Overview
1.4.1 Model SS4-AUV/-AUV2 Detector
Version SS 4-AUV: There are two (2) LED s o n the Mo del SS4-A UV Detec tor t hat i ndicat e the stat e of the
Detector. During normal operati on both LEDs will blink every 10 seconds.
If the Detector alarms to a fire, it energizes the Fire relay and turns on both LEDs in the following
sequence. One LED i s turned on immediately and the second LED wil l rapidly blink f or several seconds
indicating that the Detector's FirePic spectra is being permanently stored in the Detector's solid-state
memory (FirePi c is the several seconds of Det ector spectral data which precedes an alarm event). Once
the FirePi c data is stored, the second LED will remain on. For this version, the fire alarm LEDs turn on and
remain on until power to t he unit is cycled (turned off and on again).
If the Detector has a Fault, it de-energizes the Fault r elay and tur ns one (1) LE D on ( the LED will not light if
the Fault is a “No Power Faul t”). If the Fault condition, such as a “Low Volt age Fault”, is eliminated the
Detector will autom atically return to Normal Operation.
NOTE: Faults caused by excessive i nput voltage or due to temperatur es outsi de the operating temper ature
range require factory re-certifi c ation. Re-certification is required if a Fault is indic ated by both LEDs rapidl y
blinking (with frequency about 2 Hz.).
Version SS4-AUV2: The operation of this unit is identical to the S S 4-A UV, ex c ept the fire alarm LEDs tur n
off once the fire threat is eliminated, without power cycling of t he device.
1.4.2 Detection Rang e and Field-of View
The SS4-AUV/-AUV2 det ection range is f ield adjustabl e between 15 and 60 f t. in 15 f t. increment s to an
industry standard one square foot gasoline pan fire within 5 seconds.
The Detector incorporates a 120-degree conical F ield of View. The fire emissions received by the Det ec tor
diminish at ex treme range and edge s of the fi eld-of-view. It is recommended t hat the Det ector be point ed
at the fire thr eat area for the f astest response tim es to the sm allest size fi re. When multipl e Detectors are
used to cover large areas, the F i eld-of-Views should ov erlap to insure com pl et e coverage of the fire t hreat
area. The Fi eld-of-View is not, howev er, lim ited t o 120 degree s. Larger f i res outsi de the 120 degre e Fi el dof-View may c ause the SS4-AUV/-AUV2 to al arm. T his is based on t he Inv ersed Square L a w for r adiat ed
energy, a larger size fi re outside t he Detecti on Range and fi eld-of-view may cause the Detec tor to al arm.

1.5 Configuration Settings
The SS4-AUV/-AUV2 Detector may be reconfigured in the fiel d and thus optimized for speci al applications.
The configuration of the Detector is set using DIP switches located on the middle circuit board of the
Detector Module. The DI P switch sett ings for each configuration are listed in Table 2.
