Product Description

1 Function
1.1 Detector is intended to
detect unauthorized access into
closed protected area, and to
generate an alarm notification by
opening an alarm relay contacts.
1.2 Power supply of detector is
performed from any direct current
source with nominal voltage 12V and
pulsation amplitude not exceeding
0,1V.

2 Principle of Operation

Operation principle is based on registration of changes in
thermal emission flux occurring on crossing by a man of
detection zone consisting of sensitive zones. Each sensitive
zone consists of two elementary sensitive zones (figure 2).
Detector sensitive zones are formed by Fresnel lens and bi-
areal pyroelectric radiation reciever.
Pyroelectric reciever sends electric signal to microcontroller,
which in its turn generates an “Alarm” notification in
accordance with pre-set algorithm by opening optoelectronic
relay circuit.
