Maintenance Instrumentation and Personnel
The detector’s maintenance requires ordinary tools and suitably qualified
personnel, who should be familiar with local codes and practices.

Preventive Maintenance Procedures
The detector must be kept as clean as possible. The viewing window and the
reflector flame detector must be cleaned on a periodic basis. The frequency
of cleaning operations depends upon the environmental conditions and
specific applications. The fire detection system designer will give his
recommendations.
➣
To clean the detector:
1
Disconnect power to the detector before beginning any maintenance
including lens cleaning.
2
To clean the detector viewing window and reflector use water and
detergent, and rinse with clean water.
Where dust, dirt, or moisture accumulate on the window, first clean with
a soft optical cloth and detergent, and then rinse with clean water.
