Det-Tronics X5200 UVIR Flame Detector with Pulse Output - Manual (Page 4)

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 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 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.
oi
(OpTICaL INTEgRITy)
automatic oi
The X5200 includes 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 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
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.
