Astra-6 (Volumetric Lens)
Optic-Electronic PIR Motion Detector
Operation Manual
The present operation manual is intended for studying
operation principle, running conditions and maintenance of PIR
motion detector Astra-6
(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
1.1
Detector is intended to detect
unauthorized
access
into
closed
protected area, and to generate an alarm
notification by opening of 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.

5 Structure
Figure 3
Detector is designed as a unit consisting of a base and
removable cover. Printed circuit-board with radioelements and
screw terminal block for outside connections is mounted
inside the unit (figure 3).
Detector operability indicator for operation capability control is
installed on the printed board.
From the inner side of the detector’s cover there is a fixing
element installed, clamping and fixing the lens.
Pyroelectric detector is equipped with a cap with reflector
which forms short-range detection zone.
ATTENTION! It is forbidden to operate detector without a
cap.
