Model F120 UV/IR Flame Detector
Alarm and Delayed Alarm Test
To simulate an alarm condition, activate the ame detector test equipment within its eld of
view for at least 3 or 6 seconds, depending on the time delay settings on the detector. When
ame radiation is detected, the following will occur:
1. Red LED will illuminate to signal an Alarm (Pre-Alarm)
2. 0-20 mA Loop output changes to 12 mA
3. Alarm relay toggles between “Open on Alarm” and “Closed on Alarm”
4. When the detector continues to detect the re after the time delay (3 or 6 seconds),
the detector will signal the Delayed Alarm
5. 0-20 mA Loop output changes to 20 mA
6. Delayed Alarm relay toggles between “Open on Alarm” and “Closed on Alarm”
7. If the ame detector is set to NON-LATCHING, when the ame detector test equip-
ment has been turned off then the detector will automatically reset to normal opera-
tion.
Reset Test
If the Delayed Alarm is set for LATCHING operation, the alarm condition will remain upon
completion of the Alarm and Delayed Alarm Test.
Activate the detector’s RESET input to return the detector to normal operation. Or you may
momentarily interrupt the power to the ame detector. The following will occur upon RESET:
• Red LED will turn OFF; only green LED remains illuminated
• 0-20 mA Loop output changes to 4 mA
• Delayed Alarm relay resets and returns to normal
