Mounting
The VLI detector can be mounted in an upright or inverted position. Do not mount the detector with a
sideways orientation as shown in Figure 3-2 below.
Figure 3-2: Sideways orientation
Ensure the mounting surface is flat. This will permit an air tight seal to be achieved between the
sampling pipe and the tapered air ports on the detector.
Ensure that there is sufficient clearance to mount the detector, noting the location of air sampling
pipes and cable entry points. Due to the rigid nature of the plastic pipe, installation must provide for
sufficient movement in all pipework (air inlet, air exhaust and cable pipes) to allow pipe ends to be
easily fitted and removed.

Mount the Detector
1. Horizontally align the mounting bracket (A) and place the flat side flush against the surface.
