Detector mounting
The VESDA LaserFOCUS can be installed upright, inverted or horizontally.
Note:
Ensure the smoke detector is mounted away from obstructions and below ceiling
level.
Caution:
An exhaust deflector must be fitted for upright mounting, unless the exhaust port is
connected to a return air pipe.
Caution:
Do not install this unit on its side. There is a risk of particulate and condensation
collecting on critical elements of the detector chamber reducing the detectors
performance.
Ensure that there is sufficient clearance to mount the detector, noting the location of air sampling
pipes and cable entry points. Owing 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.

Installing the smoke detector
In all installation cases the mounting bracket must be fitted (upright) as shown in figure 4,
“Mounting bracket orientation for upright and inverted mounting,”
on page 5.
Note:
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.
Warning:
Prior to drilling the attachment holes for the mounting bracket, ensure
that all mounting surfaces (i.e. walls, cabinet sides, etc.). are clear of
electrical wiring and plumbing.
