Maintenance - Honeywell FS20X Series User Manual

● Electronic self-test failure.
● Dirty window (flashing yellow LED)

Maintenance

After the detector is installed and commissioned, little maintenance is required.
However, a test of the entire fire detection system should be performed periodically,
depending on the application. Additionally, semi-annual or quarterly testing should be
performed with the appropriate Honeywell Analytics test lamp (TL-1055 or TL-2055)
to ensure the integrity of the system.
Establish a periodic cleaning schedule. Some industrial environments may require
more frequent cleaning of the detector's window than others.
Clean the detector's window any time it is dirty or contaminated, every time the
enclosure lid is handled, if the detector fails the built-in test, or if the detector fails an
end-to-end test with the test lamp. If necessary, clean the detector module sensors
whenever the detector has been disassembled.
Use a blast of clean air or an oil-free cloth to clean the enclosure window (oil
degrades the performance of UV detectors). Do not use commercial or silicone-
based window cleaning products; they also will degrade the detector's performance.
Occassional use of a solvent such as 6% isopropyl alcohol is acceptable. No
disassembly of the detector is required for this.
WARNING
!
To avoid electrostatic discharge, wipe the enclosure only with a damp cloth.
