4.1 System Maintenance
The system will automatically compensate for dust build-up by changing the Compensation Level. However, it is
recommended that the Transmitter and Receiver lenses are cleaned periodically with a soft lint-free cloth. The
system should be isolated from the Fire Control Panel before cleaning takes place. After cleaning, verify that the
system is operating normally by following the Alignment procedure and the Fire and Fault Tests described in this
User Guide.
