Det-Tronics X3300 Protect-IR Multispectrum IR Flame Detector with Pulse Output - Manual (Page 14)

OPTICAL INTEGRITY ( oi)
The X3300 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. A successful
automatic
oi test does not produce an alarm condition.
The Protect•ir signals a fault condition when less than
50% of the detection range remains, as determined by
three consecutive
oi checks. This is indicated by the
amber color of the LED on the face of the detector. See
the “Troubleshooting” section for further information.
STARTUP PROCEDURE
When installation of the equipment is complete, perform
the “Manual
oi Test” and/or “Count Test Mode” below.
Allow 20 to 30 minutes for the detector optics to reach
equilibrium. Housing will be warm to the touch.
MANUAL Oi TEST
1. Place the keylock switch in the TEST position.
2. Press the SELECT button to display the desired
zone on the ZONE indicator on the front panel of the
controller.
3. Press and hold the TEST button to energize the test
lamps for the selected detector. The ZONE
OUTPUT LED for the tested zone flashes and the
SYSTEM STATUS display indicates a “6” (fire
condition) if the test is successful.
4. Release the TEST button. The ZONE OUTPUT LED
for the tested zone should remain on steadily.
5. Return to step 2 to test next detector.
If the system responds differently than indicated
above, proceed with the count test for the problem
zone to verify detector and wiring operation.
COUNT TEST MODE
The detector can be tested using the Count Test mode.
When in the Count Test mode, the frequency of the
digital pulses from the detector is displayed in the
ZONE and DETECTOR indicators on the controller
faceplate. The Count Test mode may be used to check
the
oi signal strength, the signal (cps) from a test fire, or
false alarm source. This can be useful during system
set-up for sensitivity and time delay settings. This test is
performed in the following manner:
1. Place the keylock switch in the TEST position.
2. Simultaneously press and release the SELECT and
TEST buttons. The Status display will change from
a “1” to an “8” indicating that the controller is in the
Count Test mode of operation.
3. Press the SELECT button until the desired zone is
displayed in the ZONE indicator on the controller
front panel.
4. Press and hold the TEST button to energize the oi
source lamps for the selected detector. The
DETECTOR/ZONE display indicates the counts per
second (cps) received from the detector. If the
counts per second exceeds 99, the FIRE LOGIC
LEDs are illuminated to indicate that the number
shown on the display must be multiplied by 10.
The normal reading for an oi test is 100 cps. For
a live fire test, 300 cps will be generated.
A zero reading may indicate a dirty window, oi problem,
faulty detector or defective wiring.
Release the Test button, the ZONE and DETECTOR
display should drop to a reading of 0 to 1 counts per
second.
TROUBLESHOOTING
WARNING
The detector contains no user serviceable
components and should never be opened.
NOTE
Since the entire unit must be returned to the
factory for repair, it is highly recommended that a
complete spare be kept on hand for field
replacement to ensure continuous protection.
