In Use Cleaning the System
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 90%
- perform LASER Targeting, Auto-Align, and Set.
How to change Compensation Level:
Use to move between icons
in the Detector Menu, until this icon is
shown
