If the detector fails this test several steps should be taken to determine if the
detector is faulty or simply needs to be re-adjusted before returning the unit.
These steps include:
1. Verify all wiring connections and appropriate power is applied to
the detector.
2. Verify that the optical line of sight is free from obstructions and re-
flective objects.
3. Apply the maintenance procedure in this manual. Repeat the test pro-
cedure. If the detector still fails the test procedure proceed with step 4.
4. Repeat the alignment procedure in this manual. If the alignment pro-
cedure is successful repeat the test procedure. If the detector still fails
the test it should be returned for repair.
NOTE: For the BEAM200S, the external power supply must be con-
nected for the test switch to work.
