By connecting one contact of a DPST, normally open, momentary switch to each of the P1
terminal 4 and P2 terminal 4 simultaneously and the other contact to (GND), the user can
perform an Alarm Test (Figure 22). Activating this switch for 0 to 14 seconds, depending on the
alarm time delay settings, can test the alarm outputs of the Flame Detector. 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 or until 3 minutes has
elapsed.
NOTE
: The latching WARN and / or ALARM will have to be reset manually.
