Conventional Field of View
Every finger in every layer
is susceptible to false
alarms from . .

from drafts or sun, as they
tend to occupy a very LARGE
percentage of a conventional
PIR’s field of view.

Curtain Detail At Mirror
“Gliding Focus Curtains - created by the smooth transition of the different focal
lengths, between the pyro and the mirror, required for maximum mirror efficiency,
i.e.. one focal length for close in detection and another for full range.”
PRESENTATION BY ARITECH / SLC TECHNOLOGIES
REV D
Detail of how parallel curtains are achieved
In order to achieve a solid curtain, with a constant beam width at
all distances, involves over 500 focal equations, this is then
polished on the mirror to give effectively infinite focal points :-

The Claustrophobic Rule
A fresnel lens detector should not be
installed in a room less than 50% of its
maximum stated range
Otherwise . . .
It may become oversensitive to small thermal
changes of static objects close in !
