LaserSense Nano Aspirating Smoke Detector Installers Handbook 11
Below or above the ceiling installations
The Nano detector is supplied with an exhaust port (see Figure 2 on page 5).
This allows the Nano 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 4 below and
Figure 5 on page 12.
