6.3 Detector test
1. Switch the FAD-420-HS-EN to test mode on the fire panel.
2. If you have activated the jumper for the tamper switch,
secure a magnet at the reed switch (E) on the side of the
detector housing.
You could use IMI-ESMAG (F.01U.142.997) magnets, for
example.
3. This bridges the tamper switch (F) and allows the cover
(B) to be removed without having to switch off the FAD-
O420 Smoke Detector (D).
4. Loosen the fastening screws (A) on the cover and remove
the cover (B).
5. Check both air filters (C) for contamination and replace
them if necessary.
If necessary, check and clean the sample tube and
ventilation tube.
6. Test the FAD-O420 Smoke Detector (D) with a suitable
test aerosol.
7. Once the detector is checked, reattach the cover, remove
the magnets, and set the detector to operating mode on
the fire panel.
