LaserSCANNER Product Manual

23

Note: 

The detection chamber, head processor card and flow sensors are factory 
calibrated as a matched set. Separating the set and replacing it with components 
from another set may cause the detector to malfunction, requiring re-calibration at 
the factory.

Recess mounting kit

These kits are used to house a detector inside a wall cavity.
