OUTPUTS
Relays
The detector is furnished with fire and fault relays. The
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.
Latching relays can be reset by removing input power
(0.1 second minimum).
An alarm condition will normally override a fault condition,
unless the nature of the fault condition impairs the ability
of the detector to generate or maintain an alarm output,
i.e., loss of operating power.
LED
A tri-color LED on the detector faceplate indicates
normal condition and notifies personnel of fire alarm
or fault conditions. Table 1 indicates the condition of the
LED for each status.
ATTENTION
The X5200 contains a source tube that is filled
with a gas mixture containing Krypton 85 (Kr
85
),
a radioactive material. Radioactive materials are
subject to regulation under U.S. and international
law. Not applicable to model X5200G, which does
not contain Kr
85
.

(OPTICAL INTEGRITY)
Automatic
oi
The X5200, X5200G, and X5200M include the Automatic
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. However, a successful Automatic
oi
test does
not produce an alarm condition.
The detector 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
CAUTION
These tests require disabling of all extinguishing
devices to avoid release resulting from a
successful test.
The detector incorporates both Magnetic
oi
(Mag
oi
)
and Manual
oi
(Man
oi
) test capabilities. These tests
provide pulses (80 to 100 CPS) to the controller (R7404
or R7494) when the detector is not in fault. If the test
is successful, the controller indicates a fire and the
appropriate zone output is active.
NOTE
If the detector is in a fault condition, a successful
Mag
oi
or Man
oi
test cannot be performed.
