VESDA VSP-962 Product Manual

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).
