19. Cleaning the System

The system will automatically compensate for dust build-up by changing the Compensation

Level.

However, it is recommended that the Detector lenses and the Reflector are cleaned

periodically with a soft lint-free cloth.

If the Compensation Level for a particular Detector remains above 130 for several days, this

indicates that cleaning should take place on that Detector.

The system should be isolated from the Fire Control Panel before cleaning takes place.

After cleaning, verify that the system is operating normally:

If the Signal Strength is between 92% and 108%

- leave the system to compensate back to 100% (this should take no more than 12 hours)

If the Signal Strength is above 108%

- reduce Compensation Level until Signal Strength is 92—108%, and wait for system to

compensate back to 100%

If the Signal Strength is below 92%

- perform LASER Targeting, Auto-Align, and Set.
