Below or above the ceiling installations 

The detector is supplied with a docking station (as shown in Figure 4 on page 
10). This allows the detector to sample from areas which may be at different air 
pressure from the detector location. Typical uses are for air duct sampling and 
allowing the installation of the detector in under-floor or ceiling voids or when 
sampling from pieces of computer related equipment. See Figure 6 and Figure 7.
