VSP-005 Filter Cartridge Replacement Instructions
The service interval of an air filter depends upon the environment. You can use the LCD Programmer or
Xtralis VSC software to change the service interval for filters. The system will generate a minor fault when the
filter has reached 80% and an urgent fault when it reaches 120% of its capacity. Xtralis recommends that the
installation and replacement dates be written on the air filter cartridge label as a physical reminder of when the
next service is expected.
Note:
The detector must have the power turned on while the air filter cartridge is being replaced.
Prior to any work or maintenance being carried out on the VESDA VLF, take the necessary steps to
advise the monitoring authority that power may be removed and that the system will be disabled.
Ensure that the area surrounding the filter is clear of dirt and debris, prior to replacement.
The filter is for single use only; it cannot be cleaned and re-used.
Ensure that the detector remains powered up during filter replacement and that a new filter cartridge is
available.
Replacing VESDA VLP and VESDA VLS Filter Cartridges
To replace the filter cartridge, follow these steps:
1. Slide down and remove the air filter cover (A).
2. Unscrew the recessed Phillips head screw (B).

filter switch.
4. Insert the replacement air filter cartridge (P/N: VSP-005).
5. Tighten the filter screw.
6. Replace the air filter cover.
7. Reset the filter counter using either the LCD Programmer or a PC running Xtralis VSC.
