Sliding Valves
Final
# Check OK
1. Can the ductwork carry the weight of the slid-
ing valves? If not, make sure the duct is
properly supported.
2. Are the sliding valves mounted straight and
tension-free in the duct? Tension on the
housing results in inadequate sealing and
noise from airflow.
3. Are the sliding valves pneumatically and
electrically wired properly?
4. Are the reed contacts of the sliding valves
connected to the system control panel?
5. Are sliding valves mounted indoors? If not,
are they adequately protected against pre-
cipitation, such as rain and snow?
6. Is the compressed air pressure for the sliding
valves 4-5 bar and the compressed air dry
and oil-free?
7. Do the sliding valves close in 4-5 seconds? If
not, reduce or increase pressure.
8. Are the pneumatic and electrical wiring guid-
ed away from potential fire areas like duct
and filter?
9. Make sure that the compressed air feed of
the sliding valves is an independent line and
not via the compressed air for the cleaning of
the filter.
10. Are the sliding valves functionally tested after
a fire test alarm.?
11. Do the sliding valves close when filter sys-
tem is shut down and open at filter start up?
# Check OK
1. After all functional testing, reset all detectors
and panels. When no alarm signals are visi-
ble, connect the Flame Guardian™ fire extin-
guishing generators. Make sure that
Guardian™ Panel is on
