IMPORTANT
Be sure to read and understand the entire
instruction manual before installing or operating the
flame detection system.
ATTENTION
The X9800 includes the Automatic Optical Integrity
(oi) feature — a calibrated performance test that is
automatically performed once per minute to verify
complete detector operation capabilities. No
testing with an external test lamp is required.
DESCRIPTION
The evolution continues with the new X9800 IR Flame
Detector. The X9800 meets the most stringent
requirements worldwide with advanced detection
capabilities and immunity to extraneous sources,
combined with a superior mechanical design. The
detector is equipped with both automatic and manual oi
test capability.
The detector has Division and Zone
explosion-proof ratings and is suitable for use in indoor
and outdoor applications.
The standard output configuration includes fire, fault
and auxiliary relays. An optional 4 to 20 mA output can
be provided in addition to the three relays. A multi-color
LED on the detector faceplate indicates detector status
condition.
The X9800 housing is available in copper-free
aluminum or stainless steel, both with NEMA 4X and
IP66 rating.
OUTPUTS
Relays
The standard detector is furnished with fire, fault and
auxiliary relays. All three relays are rated 5 amperes
at 30 VDC.
The Fire Alarm relay has redundant terminals and
normally open / normally closed contacts, normally
de-energized operation, and latching or non-latching
operation.
The Fault relay has redundant terminals and normally
open contacts, normally energized operation, and
latching or non-latching operation.
The Auxiliary relay has normally open / normally
closed contacts, normally energized operation, and
latching or non-latching operation.

4 to 20 mA Output
A 4 to 20 mA output is available as an option (in
addition to the three relays).
This option provides a 4
to 20 mA dc current output for transmitting detector
status information to other devices. The circuit can be
wired in either an isolated or non-isolated configuration
and can drive a maximum loop resistance of 500 ohms
from 18 to 19.9 volts dc and 600 ohms from 20 to 30
volts dc. Table 1 indicates the detector status
conditions represented by the various current levels.
The output is calibrated at the factory, with no need for
field calibration.
NOTE
The output of the 4 to 20 mA current loop is not
monitored by the fault detection circuitry of the
X9800. Therefore, an open circuit on the loop will
not cause the fault relay to change state or the
detector status LED to indicate a fault. The status
of the LED always follows the status of the relays.
LED
A tricolor LED on the detector faceplate indicates
normal, fire alarm and fault conditions. Table 2
indicates the condition of the LED for each status.
OPTICAL INTEGRITY (Oi)
Automatic oi
The X9800 includes the Automatic Optical Integrity (oi)
feature — a calibrated performance test that is
automatically performed once per minute to verify
complete detector operation capabilities. No testing
with an external test lamp is required. The detector
automatically performs the same test that a
maintenance person with a test lamp would perform —
once every minute, 60 times per hour. However, a
successful automatic oitest does not produce an alarm
condition.
The X9800 signals a fault condition when less than half
of the detection range remains. This is indicated by the
Fault relay and is evident by the amber color of the LED
on the face of the detector. See the "Troubleshooting"
section for further information.
Magnetic oi / Manual oi
The detector also incorporates both magnetic oiand
manual oifeatures that provide the same calibrated test
as the automatic oi, and in addition actuates the Alarm
relay to verify output operation for preventive
maintenance requirements. These features can be
performed at any time and eliminate the need for testing
with a non-calibrated external test lamp.
CAUTION
These tests require bypass of all extinguishing
devices to avoid release resulting from a
successful test.

Table 2—Detector Status Indicator

The magnetic oitest is performed by placing a magnet
by the marked location (mag oi) on the outside of the
detector. The manual oitest is accomplished by
connecting the oilead (terminal 22) to power supply
minus via an external switch. The magnet or switch must
be held in place for a minimum of 6 seconds to
complete the test. Either of these test methods activates
the calibrated IR emitter. If the resulting signal meets
the test criteria, indicating that greater than half of the
detection range remains, the Alarm relay changes state,
the indicating LED changes to red, and the 4-20 mA
current output goes to 20 mA. This condition remains
until the magnet is removed or the switch is released. If
the alarm relay is configured for non-latching operation,
it will change states and the red LED will turn to green.
If the unit has latching relays, they can be reset by
removing input power (0.1 second minimum) or by
momentarily applying the magnet or manual oiswitch.
If less than half of the detection range remains, no alarm
is produced and a fault is generated. The fault
indication can be reset by momentarily applying the
magnet or manual oiswitch.
NOTE
Refer to the Appendix for FM verification of Det-
Tronics’ patented Optical Integrity oi™ function.
COMMUNICATION
The X9800 is furnished with an RS-485 interface for
communicating detector status and other information
with external devices. The RS-485 uses MODBUS
protocol, with devices configured as slaves.
DATA LOGGING / EVENT MONITORING
Data logging for event monitoring capability is also
provided. The detector can log up to 1500 events (up
to 1000 general and 500 alarm events). Status
conditions such as normal, power down, general and oi
faults, pre-alarm, fire alarm, time and temperature are
recorded. Each event is time and date stamped, along
with the temperature and input voltage. Event data is
stored in non-volatile memory when the event becomes
active, and again when the status changes. Data is
accessible using the RS-485 port.
INTEGRAL WIRING COMPARTMENT
All external wiring to the device is connected within the
integral junction box. The screw terminals accept wiring
from 12 to 22 AWG. The detector is furnished with four
conduit entries, with either 3/4 inch NPT or 25 mm
threads.
SIGNAL PROCESSING OPTIONS
The X9800 features signal processing options. These
options determine the type of logic that the detector will
use for processing fire signals to customize the X9800 to
the application. Two signal processing options are
available for the X9800:
–TDSA enabled
–Both TDSA and Quick Fire enabled (either initiates
fire alarm).
Time Domain Signal Analysis (TDSA)
The TDSA signal processing technique analyzes the
input signal in real time, requiring the IR signal to flicker
randomly in order to recognize it as a fire condition.
Using TDSA signal processing, the X9800 ignores
regularly chopped blackbody sources (occurring in
areas where moving conveyors and hot objects in
proximity to one another result in a regularly chopped IR
signal), because it looks for a less uniform signal.
However, in the presence of a regularly chopped signal,
the unit is more susceptible to false alarms due to
sporadic IR that functions as a trigger when occurring in
conjunction with the regularly chopped signal.
Quick Fire (High Speed)
The Quick Fire (High Speed) feature can be used in
conjunction with the TDSA signal processing method.
This method overrides TDSA requirements in the event
of an intense signal. When Quick Fire is activated, the
detector is capable of responding to an intense fire
signal in less than 30 milliseconds (0.030 seconds).
Using the Quick Fire feature in conjunction with TDSA
signal processing allows the detector to provide a high
speed response to a large, non-flickering fire (such as
in high pressure gas applications) while maintaining an
ability to respond to smaller fires.
