Changing Detector Settings
1. Verify that the external 24 VDC power is turned off before connecting the
detector.
2. After applying 24 VDC power, after tests (i.e., butane lighter, FSC test lamp, or
test fires), or after resetting the detector, wait at least thirty seconds to allow its
sensors to normalize to the spectral background conditions.
3. To activate SW1/SW2/SW3 setting changes, reset the detector by cycling the
power.
4. For applications requiring analog/digital communications, refer to “Configuring
the Detector” on page 31.
