7.7 Manual Self-Test
The flame detector can test the sensor(s) and also the signal processing with help of the optional manual self-test circuit.
During a successful manual self-test the alarm relay is energized and the red alarm LED illuminates. If the detector is latched,
the alarm continues until the detector is powered off.
For the manual self-test a switch can be mounted in the controller or connected externally to a +10 to +28 VDC supply. (See Ch.
6.5 Connecting the Manual Self-Test.)
During commissioning this option can be tested by shorting the FSL100 terminals 1 & 14 for 5 seconds maximum.
1. The manual self-test can be used during commissioning to test the detector without the necessity to use a flame detector
test lamp.
2. The manual self-test is not a replacement for the functional test using a test lamp. After the commissioning is completed,
the flame detectors must be functionally tested by means of a test lamp.
Caution
Always ensure that relay operated outputs and alarms are inhibited or isolated before carrying out any work on
Alarm systems.
Always ensure that Alarm Systems are returned to Normal Operation when work is completed.
