Alarm Test Terminal
TB1, Term 4 = TEST
By connecting one contact of a normally open, momentary switch, to TB1
Terminal 4 and the other contact to TB1 Terminals 9 and 10 (DC COM), the user
can test the alarm outputs of the Flame Detector by activating this switch for one
to eight seconds depending on the alarm time delay setting. The Alarm Test will
activate the WARN and ALARM relay outputs as well as the appropriate analog
output. The Flame Detector will remain in this state until the switch is released.
NOTE - The latching WARN and/or ALARM will have to be RESET manually.
The Alarm Test feature cannot be daisy chained between two or more
FL3100/FL3101 Flame Detectors.
Analog Output
TB1, Term 5 = 0 - 20mA (Analog Output)
The 0 to 20mA output is a current signal that corresponds to the following
signals:
FAULT
0 to 0.2mA
COPM Fault
2.0 ± 0.2mA
Ready
4.0 ± 0.2mA
IR (FL3100 only):
8.0 ± 0.2mA
UV (FL3100 only):
12.0 ± 0.2mA
WARN
16.0 ± 0.2mA
ALARM
20.0 ± 0.2mA
The maximum analog output load is 600 ohms, including wiring.
