1 Function

1.1 The detector detects the breaking of

glass in closed glassed rooms, generates the
alarm notification and sends the notification to
the Control Panel of the Astra-Zitadel System
via radio channel.

Types of glass:

- conventional and protected with a polymer
film, thickness from 2,5 mm to 8 mm;

- armored glass, thickness from 5,5 mm and
6 mm;

- figure glass, thickness from 4 mm to 7 mm;

- laminated construction glass, thickness from 6 mm to 8 mm;

- tempered glass, thickness from 4 mm to 6 mm space is at
least 0,1 m2 (length of one of the sides is at least 0,3 m).

1.2 The detector supports connection of external hard-wired

detectors with NO/NC outputs of «dry contact»-type.

Note: Zone-GND Input does not have current control.

1.3 The detector is powered by lithium-thionyl- chloride bat-

tery of AA size with voltage of 3.6 V (included in the delivery
set).

2 Operating Principle

2.1 The principle of operating is based on the registration of

breaking glass by means of analysis of an acoustic signal in
the sound frequency range. The microphone is a sensor. An
electric signal proceeds from the microphone comes to micro­controller, which forms an alarm notification in accordance with
specified operation algorithm.

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

5 Structure

Fig. 3

5.1 Structurally, the detector is designed as a unit consisting of a

base and a removable cover. The unit houses a printed circuit
board with radio elements (Fig. 3).

5.2 Mounted on PCB is a Zone-GND terminal block for con-

necting external emergency detectors (gas leak, water leak,
etc.). Wire length is 3 m max.

5.3 Mounted on PCB is a Tamper Switch (S1button), which

results in the «Tampering» notification when the cover is re­moved.

5.4 Mounted on PCB are LEDs: red (for monitoring the detec-

tor’s operability) and white (for wireless network status supervi­sion).

Notes
1 If «Power failure» notification appears, change the battery

within three weeks.
2 Indication of notification on HF and LF interference, “Viola-
tion”, “Network search” is initiated for 10 to 250 minutes by a
command from the control panel or MSS interface and then
automatically ceases to save energy.

7 Operating Modes

The detector operating modes are set via radio upon a com­mand from the control panel in accordance with appropriate
Astra-Zitadel System Control Panel`s Operating Manual *.

Upon a command from Control Panel it is possible to:

1) set detector sensitivity to normal or high;

2) switch on indication for 10 to 250 min;

3) switch Zone-GND terminals channel on/off;

4) set RF supervision time;

5) set operating channel.

The normal sensitivity mode is used when the distance to
protected glass with thickness of more than 3 mm is less than

3 meters.

8 Pre-Starting Procedure

8.1 After transportation in conditions differing from those of

operation, the detector must be kept unpacked for at least 4
hours in the operating conditions.

8.2 Running Detector. Battery Replacement

WARNING! Lithium-thionyl-chloride batteries have an effect of

«passivation» to provide the possibility of long-term storage. To
provide battery normal operation after long-term storage, hold
an «activation» procedure.

Step-1

Push cover lock from base slot.
Remove cover

Step-2

Insert the battery (To replace battery remove the old one and
after no less than 10 sec install the new one).

The LED will light up one time for 1 to 20 seconds - battery
activation and check period.

If after 20 seconds the red LED flashes with a triple blink
every 25 seconds, re-activate the battery by removing, and
after at least 10 seconds reinserting it.

As a last resort, use a piece of wire to close the battery’s

positive and negative poles for 2-3 seconds.
WARNING! Closing the poles for more than 3 seconds leads
to battery discharge

8.3 Registering the Detector in the Wireless Network

Detector registration is required for detector identification in the
wireless network in which it shall operate.

Step-1

According to Astra-Zitadel System Control Panel`s Operating
Manual * perform the following procedure:

1) Install Software ** (MSS Astra-Z, Pconf-Z or MSS Astra

Pro) intended for configuring Control Panel.

2) Create wireless network

Step-2

Perform p. 8.2

Step-3

Switch the control panel to Wireless device registration
mode by the method described in the appropriate Control
Panel Operating manual *

Step-4

Initiate detector registration procedure by one of 2 methods:

а) using the LT (step-5);
b) using the Reg plug and the Tamper switch (step-6)

WARNING!
Avoid to initiate registration procedure on several detec­tors simultaneously

Step-5

Initiating Detector Registration Procedure Using LT:

- press the lower LT button and wait until the beam appears;

- shine the laser beam on the detector indicator;

- illuminate the indicator for 1 s.
The detector`s red LED lights up for 2 seconds, then the
detector switches to wireless network search mode and the

white LED blinks at a frequency of 5 Hz
