8. Maintenance Instructions
8.1 Scope
This chapter deals with preventive maintenance, describes possible faults in
detector operation and indicates corrective measures. Ignoring these instructions
may cause problems with the detector and may invalidate the warranty. Whenever
a unit requires service, please contact the manufacturer or its authorized
distributor for assistance.
8.2 Maintenance Instrumentation and Personnel
The detectors’ maintenance requires ordinary tools and qualified personnel, who
should be familiar with local codes and practices.
8.3 Preventive Maintenance Procedures
The detector must be kept as clean as possible. The viewing window and the
reflector of the 20/20CTIP and 20/20CTIN Flame Detector Models 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. Use of the optional AIR SHIELD Model
20/20-920 is highly recommended and will help to keep the window clean and
prevent dirt from accumulating on the window.

including lens cleaning.

rinse with clean water.

optical cloth and detergent, then rinse with clean water.

functionally tested every six months. This test should also be carried out for any
reason the detector has been opened.
