Astra-642

Ultrasonic Volumetric Detector

Operating Manual

Rev. 642-v2_6_en 1

The operating manual describes the operating principle, opera­tional and maintenance conditions pertaining to ultrasonic volu­metric detector Astra-642 (hereinafter “detector”) (Fig.1).
The manufacturer reserves the right to introduce changes
which update and retrofit the detector without prior notice. All
such changes will be described in an updated revision of the
operating manual.

1 Function

The detector detects intrusion into a pro­tected volume of a closed room and gene­rates an alarm notification by opening out­put contacts of the signaling relay.

The detector is powered by any DC
source with rated voltage of 12V and pul­sation amplitude not exceeding 0.1V.

2 Operating Principle

2.1 The operating principle of

the ultrasonic channel (herei­nafter referred to as the US­channel) is based on the
Doppler Effect – changes in
frequency of ultrasonic
waves emitted by the detec­tor, when they are reflected
from a moving object.
An electric signal from the ul­trasonic sensor is sent to a
microcontroller, which – if sig­nals are present in both chan­nels and in accordance with a
present operation algorithm –
generates the “Alarm” notifica­tion by opening the output cir­cuit of the optic-electronic relay.

2.2 Schematics of the detec­tion zone are shown in Fig. 2.

Note – The US-channel de-
tection zone depends on a
specific room: some objects
absorb or reflect ultrasound,
thus distorting the detection
zone.

5 Structure

Fig. 3

Structurally, the detector is a unit comprised of a base and a
removable cover.

The unit houses a printed circuit board with radio elements,
screw terminal blocks for external connections, ultrasonic
transmitter and receiver (Fig. 3).

A switch installed on the printed circuit board generates a

“Tampering” notification when the cover is detached by open-
ing the ТМР circuit (irrespective of whether or not the detector

power supply is switched on).
The following indicators are mounted on the printed circuit

board: red – for detector status monitoring, blue – for interfe­rence indication.

The US-channel detection range can be adjusted using the
US-channel range controller.

 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 ПАМ
plug or in 1 min. after starting of detector stand-by mode with
jumper installed previously on ПАМ plug. “Alarm” notification
is indicated in 1 min. after violation of protected area. To
switch the mode off and reset indication, remove jumper from
ПАМ plug or switch power off.

8 Installation and Pre-starting Procedure

8.1 Works on installation, mounting, maintenance and

operation of detector should be performed by only qualified
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 Selecting a Location

8.3.1 Recommended mounting height

8.3.2 The detector shall be mounted on load-bearing, vibra-

tion-free structural elements.

8.3.3 Alarm loop and power circuit wires shall not be located near
power cables.

8.3.4 This detector type allows mounting several detectors in
the same room. Detectors shall be placed not closer than 5

m from each other.

8.3.5 It is not permitted to operate the detector in a room with

noise levels exceeding 75 dB.

8.3.6 Do not mount the detector near curtains (blinds) and
other object which may move when air currents move through
the room.

8.3.7 When a room is being protected, it is recommended to
close doors and ventilation windows, switch off fans, air condi­tioners and other possible sources of strong air currents, and
make sure there are no animals and insects in the room.

Step-14

Switch on the detector power supply, red and blue indicators
shall alternatively blink for not more than 60 s – it means the
detector is being switched to the standby mode.

If within 30 s after switching to the standby mode the detec-

tor gives the “Interference” notification:
1 Make sure there is no extra emission on the operating fre-

quency of the detector and exclude such emission if
present.
2 Remove any object, vibrating/moving rhythmically by the

detector.

Step-15

Make a TEST-pass through a
protected area with speed of 0.3 m/s
and 2 m/s.

Make sure the “Alarm” notification is

given for every movement (the indi­cator lights up red for 4 s).
Repeat the TEST-pass in different
directions

Step-16

Push out cover lock from
base slot.

Remove detector cover

Step-17

If required, adjust the US-channel
detection range in accordance with
protected room dimensions using
the US-channel range controller

min – 5 m range;
max – 10 m range

Step-18

Depending on a selected operating
mode, install jumpers on ИНД and
ПАМ plugs

Step-19

Place the detector cover back
into its position (until it clicks
shut)

Step-20

If during alarm system testing in the initial operating period
(1-2 weeks) you receive false “Alarm” notifications due to
specific characteristics of a protected room, remove jumper
from РЕЖ plug

8.5 To provide for reliable operation of the alarm system it is
recommended to test and maintain the detector at least

once a month.

The detector shall be tested in the following way:

- walk through the detection zone;

- make sure that the “Alarm” notification is present on the

control panel and, if indication is permitted, on the detector
indicator (lights up once for 4 s for each movement).
The detector shall be maintained in the following way:

- inspect integrity of the detector body, reliability of contacts
and mounting, clean the detector from any dirt accumulated.
