Руководство по эксплуатации извещателя ТЕКО Астра-9

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.
