teko Astra-9 Operating Manual

The present operation manual is intended for studying operation
principle, running conditions and maintenance of PIR motion de-
tector Astra-9 (hereinafter referred to as "the detector") (Fig.1).
1 Function
Detector is intended
unauthorized access
protected area, and to generate an alarm
notification by opening of alarm 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 (figure 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.
The detection zone size can
be changed by changing po-
sition of the detector printed
circuit board. If the intrusion
detection range is reduced to 7 m, density of the sensitive
areas will increase.

PCB
Structurally, the detector is designed as a unit consisting of a
base and a removable cover. Printed circuit-board with
radioelements and
connections are mounted inside the unit (Fig. 3).
Mounted on the detector base is an eccentric; by rotating the
eccentric one can change the position of the printed circuit
board.
Mounted on the circuit board is an indicator for detector operabil-
ity supervision.
Mounted inside the detector cover is a fixing piece pressing
down the lens and fixing its position.
The pyroelectric sensor is equipped with a reflector cap which
forms short-range detection zone.
WARNING! It is prohibited to operate the detector without
the cap.
