2.2.5. Use of deviating mirrors
The control of any dangerous area, with several but adjacent
access sides, is possible using the linear version without
integrated Muting sensors and well-positioned deviating mirrors
(see section 12 “Accessories”
).
Fig.10 shows a possible solution to control three different access
sides, using two mirrors placed at a 45° angle respect to the
beams.

The operator must respect the following precautions when using
the deviating mirrors:
The alignment of the emitter and the receiver can be a very
critical operation when deviating mirrors are used. Even a very
small angular displacement of the mirror is enough to loose
alignment. A laser pointer (available as an accessory) can be
used to avoid this problem.
The minimum safety distance (S) must be respected for each
single section of the beams.
The effective operating range decreases by about 15% by using
only one deviating mirror, the percentage further decreases by
using 2 or more mirrors (for more details refer to the technical
specifications of the mirrors used).
Do not use more than three mirrors for each device.
The presence of dust or dirt on the reflecting surface of the
mirror causes a drastic reduction in the range.
