5.1
Maintenance
This section describes the basic maintenance steps that should be taken to keep
the detector in good working condition.
5.1.1
General Procedures
Maintenance should be performed by suitably qualified personnel, who are
familiar with local codes and practice. Maintenance requires ordinary tools.
5.1.1.1
Cleaning
The detector must be kept as clean as possible. Clean the viewing window and
the reflector of the flame detector periodically.
The frequency of cleaning operations depends upon the local environmental
conditions and specific applications. The fire detection system designer will give
his recommendations.
To clean the detector viewing window and reflector:
Disconnect power to the detector before proceeding with any maintenance
including window/lens cleaning.
Use water and detergent, and then rinse the viewing window with clean
water.
Where dust, dirt, or moisture accumulates on the window, first clean with a
soft optical cloth and detergent only, and then rinse with clean water.
5.1.2
Periodic Procedures
In addition to preventive cleaning and maintenance, the detector should be
functionally tested every 6 months or as dictated by local codes and regulations.
These tests should also be conducted if the detector has been opened for any
reason.
5.1.2.1
Power-Up Procedure
Perform the power-up procedure every time power is restored to the system.
Follow the instructions described in
on page 47.
