Maintenance
The maintenance outlined below should be performed at least once annually.
Verify that the fixture is functional in all operating modes with no indication of an
alarm condition on alarm indicator lights, alarm dry contacts, or digital monitoring
interfaces.
Verify that the photoelectric control operates the system in the correction operating
mode (day/night), light color (white/red) and intensity (day/night intensity) when
exposed to light and dark ambient lighting conditions.
Inspect the fixture for any type of obstruction that could block light output at any
point along the 360 degree horizontal output of the fixture. Note that multiple
fixtures may be used to achieve 360 degree coverage.
Inspect lenses and transparent covers for damage.
Clean the fixture lens or transparent cover using a mild detergent and soft
nonabrasive cloth.
Inspect all electrical wiring connections for corrosion, arcing, damage, insulation
degradation or loosening of the connection. Correct, replace or secure as needed.
Inspect all interconnecting cables and power supply cables and conduits for
damage.
Verify the all cables are fastened securely at appropriate intervals to prevent
damage.
Inspect all electrical components for evidence of damage caused by lightning or
power line induced electrical surges. Replace any components showing evidence
of damage.
Inspect fixtures and enclosures for water infiltration and insect infiltration. Replace
any damaged gaskets or seals. Install plugs to close any unused conduit ports
that may allow insect infiltration.
Verify that all breathers and drain holes are clear of blockages.
