Astra-516 (Volumetric Lens)
Optic-Electronic PIR Motion Detector
Operating Manual
Rev. 516-v1_6_en
The present operation manual is intended for studying operation
principle, running conditions and maintenance of PIR motion
detector Astra-516
(hereinafter “detector”) (Figure 1).
The manufacturer reserves the right to make alteration
regarding refinement of the product without prior notification. All
changes will be imported into new edition of the operation
manual.
1 Function
Detector
is
intended
to
detect
unauthorized access into closed
protected area, and to generate an
alarm notification by opening of
sygnaling relay contacts.
Power supply of detector is performed
from any direct current source with
nominal voltage 12V and pulsation
amplitude not exceeding 0,1V.
2 Operating Principle
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 (Fig. 2).
The sensitive zones are
formed by a Fresnel lens
and a bi-areal pyroelectric
sensor.
An electric signal from the
pyroelectric sensor is sent
to a microcontroller which
–
in accordance with a preset
operation algorithm
– gene-
rates an
“Alarm” notification
by opening optoelectronic
relay circuit.

5 Structure
Fig. 3
Structurally, the detector is designed as a unit consisting of a
base and a removable cover. The unit houses a printed circuit
board with radio elements and screw terminal blocks for exter-
nal connections (Fig. 3).
Mounted on PCB is an indicator used for detector operability su-
pervision.
The pyroelectric sensor is equipped with a cap.
WARNING! It is prohibited to operate the detector without
the cap.
The spherical lens provides for the distortion-free detection
zone and forms the short-range detection zone.
