teko Astra-621 Operation Manual

The present operation manual is intended for studying
operation principle, running conditions, storage and technical
maintenance of dual channel detector Astra-621 (hereinafter
"detector").
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
The detector is intended for:
- detection of unauthorized access into an
enclosed area, and generation of an alarm
notification by opening contacts of
dedicated alarm relay;
- detection of glass breaking of glazed
constructions of an enclosed area, and
generation of an alarm notification by
opening contacts of dedicated alarm relay.
Types of protected glass:
- conventional and protected by a polymer
film, thickness from 2.5 mm to 8 mm;
- armored glass, thickness 5.5 mm and 6
mm;
- figure glass, thickness from 4 mm to 7 mm;
- tempered glass, thickness from 4 mm to 6 mm.
Size of glass: area of at least 0.1 m
0.3 m length).
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
2.1
Both IR and Acoustic (AC) detection channels are
activated independently and processed by two separate relay
outputs.

Operation Manual
2.2
Operation principle of IR channel is based on registration
of thermal background change of the room occurring on
crossing sensitive zones by a man (Figure 2). Detector
sensitive zones are formed by Fresnel lens and bi-areal
pyroelectric radiation receiver. Pyroelectric receiver sends
electric signal to microcontroller, which in its turn generates an
"Alarm-IR" notification by opening of output circuit of
optoelectronic relay in accordance with pre-set algorithm.
2.3
Sensitive element of AC channel is an electret
microphone with integrated amplifier. Trasmitter modifies
acoustic vibrations into electric signals which are amplified and
sent to microcontroller. Microcontroller processes received
signal and in accordance with preset algorithm takes decision
about presence of glass breakage or low-frequency and high-
frequency interference
notification.
2.4
To connect the detector to an alarm loop (hardwired
zone) optic-electronic signaling relays are used.
