The X5200 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 yellow 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 disabling of all extinguishing
devices to avoid release resulting from a
successful test.
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 oi
lead (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 UV and IR emitters.
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 0-20 mA current output goes to 20 mA.
This condition remains until the magnet is removed or the
switch is released, regardless of whether the relays are set
for latching or non-latching operation.
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.

COMMUNICATION
The X5200 is furnished with an RS-485 interface for
communicating status and other information with external
devices. The RS-485 uses MODBUS protocol, with the
detector configured as a slave device.
NOTE
The EQP model uses LON/SLC communication.
RS-485 communication is not available on the
EQP model.
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
oifaults, 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 or the EQP
controller.
INTEGRAL WIRING COMPARTMENT
All external wiring to the device is connected within
the integral junction box. The screw terminals accept
wiring from 14 to 24 AWG. The detector is furnished with
four conduit entries, with either 3/4 inch NPT or 25 mm
threads.
SIgNal PROCESSINg OPTIONS
The X5200 features signal processing options for both the
UV and IR sensor. These options determine the type of
logic that the detector will use for processing fire signals
to customize the X5200 to the application.
IR DETECTOR OPTIONS
The IR detector in the X5200 can be programmed for:
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 X5200 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.
