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 biareal 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.

“+” - jumper is installed on both plug pins
“-” – jumper is removed (or installed on one plug pin)
The “Alarm memory” mode allows registering the fact
and number of zone violations in prortected area, and is
reflected in corresponding notification .
The mode is activated in 1 minute after installation of
Mem plug or in 1 min. after starting of detector stand-by mode
with jumper installed previously on Mem plug. “Alarm”
notification is indicated in 1 min. after violation of protected
area. To switch the mode off and reset indication, remove
jumper from Mem plug or switch power off.
TEST-pass allows revealing precise location of sensitive
zones formed by the lens. On expiry of 8 min the detector
automatically starts its stand-by mode.
8 Installation and Pre-starting Procedure
8.1 Works on installation, mounting, maintenance and
operation of detector should be performed only by quaified
persons.
8.2 After transportation in conditions differing from those of
operation keep detector unpacked under supposed operation
conditions for at least 4 hours.
8.3 Selection of Installation Place
8.3.1 Recommended height of installation
8.3.2 In capital buildings it is recommended to install
detector on bearing wall.
8.3.3 In light metalwork buildings one should avoid to install
detector directly on the wall, it is recommended to install
detector on bearing carriers.
8.3.4 Wires of signaling zones and power supply circuits should
be located far from power cables.
8.3.5 It is recommended to close all doors, air-vents, switch
off fans, air-conditioners and other sources of intense air flows
in the room during protection period.
8.3.6 It is not recommended to install detector in the
following places.
