X Maintenance
(1) If the detector gives fault signal after working for a long time, first
check whether the detector is damaged or not, and make sure
that it is fixed to the wall or other fixity. Then check whether it is
the accumulating dust and positional excursion, causing
compensation fault, then consider other types of fault.
(2) If emitting window, receiving window and reflector surface are
found contaminated, clean them with soft cloth and alcohol
(avoid scraping). Never use water or other chemicals.
Commission the detector again after cleaning.
(3) The detector is fire protection product, whose operation must be
well recorded by the personnel on duty and shift.
(4) Personnel on duty should be familiar with the functions and
operation process of the device in order to avoid mis-operation.
(5) Test alarm function once half a year.
