SECTION 1: FAMILIARIZATION
1.1 Introduction
The Model SS4-AI Infrared Flame Detectors can be used in the FS2000
Fire Early Warning System or in the Stand-Alone mode. This model is
housed in an Explosion-Proof enclosure and incorporates built in optical
testing of both the Detectors and lens.
The Detector maximum alarm range is 45 feet for a one square foot
gasoline with a 120 degree circular field of view. This Detector design
features dynamic signal processing that utilizes infrared band and visible
band sensor elements. For Special Applications Only – Consult
Factory.
The only difference between a FS2000 System Model SS4-AI
Detector and a Stand-Alone SS4-AI Detector is how each is wired
and the use of the fault relay. However, there are operational
advantages when the Model SS4-AI Detector is connected to a
FS2000 Controller and FireBus.
The Model SS4-AI Detector also has the flexibility to be re-configured in
the field. It is simple to install and operate because its built in self-testing
does most of the work. The only real maintenance is to wipe the Detector
window lens clean and perform any periodic testing required by the
manufacturer of the Fire Control and Suppression System.
1.2 Stand-Alone Operation
For Stand-Alone operation, the Model SS4-AI Detector may be connected
to a FM/UL Approved Fire/Security Panel. The Model SS4-AI Detector
operates on 24 volts DC. The Model SS4-AI Detector, when operated in
the Stand-Alone mode, uses its Fire, Fault, and Verify (optional) relays to
interface to FM/UL Approved Fire /Security Panels. For Stand-Alone
operation, the Model SS4-AI's Fault relay is automatically configured by
its on-board microcomputer. The input current of the Model SS4-AI
Detector increases about 15 milliamps in the Stand-Alone mode compared
to with connected to theFS2000 System. The Fault relay is not available
for use when the Model SS4-AI Detector is wired to the FS2000 System.
1.3 FS2000 System Operation
For FS2000 System operation, the Model SS4-AI 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 Model SS4-
AI Detector and RS-485 digital communication (Refer to Honeywell
Analytics document MN0003 entitled "FS2000 FIRE EARLY WARNING
SYSTEM - INSTALLATION and OPERATIONS GUIDE"). For special
remote alarm applications, users may connect directly to the Model SS4-
AI's Fire four pin relay connector. (Note: When the Model SS4-AI Detector
is connected to the FS2000 System using FireBus communication, the
Controller automatically disables the Model SS4-AI's Fault relay.)

1.4 Overview
1.4.1 Model SS4-AI Infrared Flame Detector
The Model SS4-AI Infrared (IR) Flame Detectors are micro-computerized
devices that see the visible and infrared spectral bands. The SS4-AI
Detector Module is contained in an Explosion-Proof and Weather-Proof
housing which is approximately 4 3/4 inches in diameter and 4 3/4 inches
long. The housing has two integral 3/4 inch NPT conduit openings for
wiring and an optional Swivel Mount (Model SM4) for greater flexibility in
mounting locations.
There are two (2) LED's on the Model SS4-AI Detector that indicate the
state of the Detector. During normal operation both of the LED's blink will
every 10 seconds.
If a Model SS4-AI Detector has a Fault, it de-energizes its Fault relay and
turns on one (1) of its LED’s. (The LED will not light if the Fault is a “No
Power Fault”.) If the Fault condition is cured, such as a “Low Voltage
Fault”, 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. Re-certification required
Faults are indicated by both LED’s rapidly blinking. (about 2 Hz.)
If a Model SS4-AI Detector alarms to a fire, it energizes its Fire relay and
turns on its two LED's 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 that preceded an alarm event.) Once the FirePic data is stored the
second LED will remain on.
1.4.2 Detection Range
The detection range of the detector is field adjustable between 15 (fifteen)
and 45 (fourtyfive) feet to an industry-standard one square foot gasoline
pan fire within 5 seconds. Each detection range is calibrated to a one
square foot fire. The Detector’s ranges are optimized but not limited to a
specific distance. A larger size fire outside the set range may cause the
Detector to alarm based on the “Inverse Square Law” for radiated energy.
1.4.3 Field-of-View
120 degrees circular - minimum. The fire emissions received by the
detector diminish at extreme range and edges of the field-of-view. It is
recommended that the detector be pointed at the fire threat area for the
fastest response times to the smallest size fire. When multiple detectors
are used to cover large areas the Field-of-Views should overlap to insure
complete coverage of the fire threat area. The Field-of-View is not limited
to 120 degrees, larger fires outside the 120 degree Field-of-View may
cause the detector to alarm.
1.4.4 Configuration Settings
The SS4-AI Detector may be reconfigured in the field for special
applications. The configuration of the Detector is set from a dip switch
located on the middle circuit board of the SS4-AI Module. These settings

OPERATOR MANUAL //
SECTION 1: FAMILIARIZATION
HONEYWELL 6
allow the detectors to be optimized for the specific application. The DIP
switch settings for each configuration are listed in Table 2: Configuration
Dip Switch Settings on page 12. The reconfigurable options include:
1. Fire Verify Relay - The Verify Relay may be disabled or enabled
with several Verify Time settings. It also may be set to act as another Fire
Relay. The Verify Time may be set from 5 to 30 seconds in 5 second
increments. The Factory setting is the Verify Relay is Disabled.
With the Verify Relay enabled and a Verify Time is set the Verify Relay will
energize and the Fire Relay will de-energize if the fire conditions are still
present at the end of the Verify Time. If the fire conditions are not present
the Detector will wait 5 seconds plus another Verify Time period to test for
the fire conditions. This wait and verify time will repeat 10 times or until
the fire is verified. This ends the verify process. If the fire is not verified
the Fire Relay will remain energized unless Non-Latching mode is set. If a
subsequent fire is detected the entire verify process will repeat. The state
of the Fire and Verify Relay after the verify process will depend upon
whether Latching or Non-Latching mode is set.
NOTE: When the Verify Relay is enabled and Verify Time is
set the Fire Relay will de-energize when the Verify Relay is energized.
2. Latching / Non-Latching - The Fire Relay and Verify Relay may be
set in a Latching or Non-Latching mode. If Latching mode is set the Fire or
Verify Relay will remain energized until the Detector is reset (Powered
down and up). When Non-latching mode is set the Fire Relay will reset
after 10 seconds. Unless the Verify Relay is enabled with a Verify Time,
then the Fire Relay will remain energized until the Verify Relay is energized
or until the end of the verify process. (see Fire Verify Relay above.) If the
Verify Relay is energized the Verify Relay will de-energize after 10
seconds. The Factory setting is Latching. Non-Latching mode may not
meet some Fire Codes. Consult with authority having jurisdiction before
using the non-Latching setting.
3. Test Period - This setting if for the Through-the-Lens test. The
Through-the-Lens test is run periodically. The test period may be set to 6
or 30 minute periods. The Factory setting is 30 minutes. If 6 minute
periods are set this may affect the life expectancy of the source tube. The
6 minute period may be required in applications where the lens is obscured
with great frequency.
4. Fire Detection Range Setting - 15, 30, or 45 feet. The SS4-AI
Detector has been calibrated to alarm on an industry standard 1 sq. ft.
gasoline fire for each of the range settings. If the Range is set to 15 feet,
the detector will require a much larger gasoline fire at 45 feet to declare an
alarm. These settings are not simply sensitivity settings. They are
calibrated to the characteristics of fire emissions at the set ranges. The
Factory setting is 45 feet. This setting should only be changed if the
detector is located close to the fire threat area and there is abnormally high
IR activity.

1.4.5 Testing
The SS4-AI Detector has both active and passive built-in self-test systems.
The detector uses passive testing for virtually all internal electronic
systems.
The Model SS4-AI Detectors and the system they are connected to should
be periodically manually tested to insure proper function of the entire Fire
Protection System. To test the Model SS4-AI Detectors manually (where
open fires are might be a safety hazard) for both optical path and window
cleanliness, use a Honeywell Analytics Model FT-2145 Test Lamp.

HONEYWELL 8
SECTION 2: INSTALLATION
2.1 Installation Procedure
This section describes the installation of the Model SS4-AI Detector for the
Stand-Alone mode. It is recommended that junction boxes be used to wire
the Model SS4-AI Detectors. Determine a mounting location for the
detector which is within the detectors range (see Detection Range and
Field-of-View) and has a clear view of the fire threat area. Where multiple
detectors are used to cover a large area, the detectors should be located to
allow overlapping Field-of-Views. Determine the configuration settings for
the device and the number of connections to be used. (Fire, Fire Verify,
Fault, and Power) The configuration settings and number of connections
will depend on the Detection Range desired and the type of Fire Control
Panel used. For Configuration information see the Dip Switching Setting
chart and the manual for your Fire Control Panel.
2.1.1 Installation Precautions
The following precautions should be observed during installation of Model
SS4-AI Detectors.
1. Double-check to make sure that the external electrical power is
turned OFF before connecting to the Model SS4-AI Detector.
2. Do not handle the Model SS4-AI Detector's module (with its
printed circuit boards) without being adequately grounded.
Printed circuit board components are susceptible to damage from
electrostatic discharge. Grounding may be accomplished by
wearing an anti-static wrist strap connected to an earth ground.
2.1.2 Conduit Installation
Model SS4-AI Detectors should be located to cover the specific "fire threat"
areas.
When planning the conduit, observe the following recommendations.
1. If only one of the two ½ inch NPT conduit openings on the Model
SS4-AI Detector enclosure is used, seal the unused opening with a
threaded plug.
2. In areas where moisture may accumulate, install an approved
conduit trap or drain.
3. A seal shall be installed within 6 inches of the enclosure for
applications requiring a Class I, Div. 1 Explosion-Proof rating.

OPERATOR MANUAL // SECTION 2: INSTALLATION
HONEYWELL 9
2.1.3 Wiring Recommendations
The Honeywell Analytics recommends using junction boxes to help prevent
problems with intermittent connections. Install a junction box near each
Model SS4-AI Detector location. Next, wire each Model SS4-AI Detector to
its junction box. Use screw-down terminal strips inside the junction box to
make the connections to the Detector's terminals and a UL/FM Approved
Fire Alarm Panel. Use UL/FM Approved junction boxes and terminal strips.
Avoid wire splices. However, if wire splices are necessary, solder all
splices. The use of good wiring practices will greatly improve the ease of
installation, improve reliability, and allow easier servicing.
2.1.4 Power Supply Considerations
The Model SS4-AI Detector uses 24 volts DC at a maximum current of
75 milliamps. Make sure that the Panel's power supply can handle the
current load of the total number of Model SS4-AI Detectors connected to
it. For example, if 10 Model SS4-AI Detectors are used on one Panel's
power supply, (multiply 10 times 75 milliamps), the Panel's power supply
must be able to handle at least 750 milliamps (3/4 amps). This current
load must also be considered when calculating the Panel's power backup
requirements for 24 hour backup.
