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 over-ride 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 tricolor 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 detector status.
OpTICAL INTEGRITY (
Automatic o i
The X9800 includes the Automatic Optical Integrity
(o i ) feature — a calibrated performance test that is
automatically performed once per minute to verify
complete detector operation capabilities.
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 o i test 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 yellow color of the LED
on the face of the detector. See the "Troubleshooting"
section for further information.

No testing
Magnetic o i / Manual o i
These tests require disabling of all extinguishing
devices to avoid release resulting from a
successful test.
The detector incorporates both magnetic o i and
manual o i 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.
If the detector is in a fault condition, a successful
magnetic o i or manual o i test cannot be
performed.
The magnetic o i test is initiated by placing a magnet
at the marked location (mag o i ) on the outside of the
detector. This action causes the detector to immediately
send pulses to the controller. Controller response is as
follows:
•
The Zone LED blinks.
•
The digital display indicates which Zone is in alarm.
•
The status indicator shows "6" (fire).
