7.3 Replacing the Intelligent Filter
The detector constantly monitors the difference between the flow of filtered and un-filtered air into the
manifold. The flow of filtered air decreases when compared to that of un-filtered air as dirt and other particles
accumulate in the Intelligent Filter. Although it is recommended to replace the Intelligent Filter every two
years, environmental conditions dictate the actual frequency of Intelligent Filter replacement.
The detector reports a fault condition that requires replacement of the Intelligent Filter when the flow of filtered
air falls below the minimum threshold when compared to the flow of un-filtered air.
Remove the Intelligent Filter
1. Set the detector to Standby mode. Refer to Section 7.1 for further information.
2. Remove the front cover. Refer to Section 7.2 for further information.
3. Unclip the Intelligent Filter (A) by pulling the locking lever outward (B).
4. Remove the Intelligent Filter.
