9 Maintenance
The VESDA VLC-400 detector requires little regular maintenance as the majority of potential failures are
monitored.
There are only two serviceable items, the filter cartridge and the aspirator.
Note: The rear cover of the detector MUST NOT be removed, as this will void the warranty.
9.1 Schedule
Table 9-1 lists the maintenance schedule necessary to maintain the VESDA VLC-400 in peak working order.
Action Frequency Details
Check power supplies Every month Test in accordance with suppliers
instructions.
Note: Where the condition of the battery
is regularly checked automatically,
less frequent manual checks may
be applicable.
Check pipe work Every 6 months Check that all pipe runs are intact, that pipe
supports and joints are firm and that the
sampling holes are free of dirt.
Check air flows Every year Check logs to verify that no airflow faults
have occurred.
Where possible use Xtralis VSC to read the
airflow readings (including the raw airflow
readings).
Any sign of drift should be investigated.
Check filter Every year Check that there are no filter faults (where
possible use Xtralis VSC to read the current
filter counts).
Change Filter Every 2 years Fit a new filter cartridge regularly depending
on the relative cleanliness of the protected
environment. For example, every 2 years in a
normal environment, up to 5 years in a clean,
air conditioned computer room or every year
or less in an area exposed to a dusty or
smoky atmosphere
Smoke test Every year Isolate the detector from the FACP. Set the
detector in Test mode and introduce smoke
into the end cap. Refer to Chapter 8 for further
information.
Compare response times with those
previously recorded and investigate any
discrepancies.
Flush sampling points Every 2 years Isolate the detector from the FACP, remove
pipe from the inlet port and connect a vacuum
cleaner. Run the cleaner for several minutes.
Clean sampling points As necessary If flushing does not clear the sampling points
then they must be physically cleared.
