VESDA Filter VSP-962
To maintain the operational integrity of the detector, it is recommended that the Filter be replaced every two
years, or when a filter fault occurs. It may be necessary to replace the filter more often where the detector is
installed in environments that experience high levels of contamination.
Remove the Filter
Note that it is not necessary to turn off the 24V DC power to the detector when removing and replacing the
filter. The detector will turn off the aspirator when it detects that the filter has been removed and a fault will be
signaled.
1. Open the front door. Ensure that the area around the filter is free of lint and dust before removing the
filter.
2. Press on release mechanism in the direction arrowed (Figure1-1).
