What is SERIE A03 PRO?

SERIE A03 PRO is a modern indoor intrusion detection system that uses passive seismic sensors to protect doors, windows, glazed surfaces, burglar bars and walls from intrusion attempts. The system features a multi-zone digital analysis board that manages up to 8 sensors on 4 channels, with configuration via mobile app.

What are the main advantages of A03 PRO compared to the classic SERIE A03?

A03 PRO offers significant innovations: configuration and calibration via free mobile app (iOS and Android), native support for star wiring, two-wire balanced sensors, and centralized management of up to 8 sensors with a single analysis board. All while maintaining the proven and high-performance detection technology of the historic SERIE A03.

How many sensors can I connect to a single analysis board?

The BR-A03P-Z4 analysis board has 4 communication channels. To each channel you can connect two sensors of the same type, for a total of 8 sensors. The only exception is the non-balanced detector SN-A03P-WLT, which allows creating detection lines up to 10 sensors per channel.

Do I need special equipment to configure the system?

To configure and calibrate the system you need the DG-DEA-WF2 Wi-Fi dongle and a mobile device (smartphone or tablet) with the free service app installed, available for iOS and Android. The app allows you to configure and calibrate detectors via a secure Wi-Fi connection, even from different rooms or floors than where the analysis board is located.

What types of detectors are available?

SERIE A03 PRO offers four specialized detector models: DRM for doors and windows (with and without magnetic contact), GL for glazed surfaces, WL for walls and ceilings, and GR for metal burglar bars. Each model is optimized to detect specific types of attack on different structures.

What types of alarm can the system generate?

The system can generate differentiated alarms by attack type: pre-alarm, break-in (low intensity shocks), breaking through (high intensity shocks), and drilling/cutting (continuous vibrations). It also signals sensor tampering (removal, cable cut) and power supply anomalies. The BR-A03P-Z4 board has 10 NC solid-state outputs for connecting to an alarm panel.

What is star wiring and why is it advantageous?

Star wiring allows connecting each sensor directly to the analysis board, rather than in series. This architecture offers maximum installation flexibility, simplifies troubleshooting, and allows creating point alarm zones with one or two sensors. SERIE A03 PRO natively supports this connection mode thanks to multi-balanced two-wire lines.

Q: How does the system work?

The system uses passive seismic sensors that detect shocks and vibrations generated by intrusion attempts. The digital analysis board, equipped with a powerful ARM CPU, processes signals through advanced filters to discriminate different types of attack: break-in, breaking, breaking through and continuous vibrations from drilling and cutting.

Q: Is the system certified?

Yes, the BR-A03P-Z4 analysis board is IMQ certified with security grade 3. All detectors and analysis boards are designed, manufactured and assembled in Italy, at the DEA Security facility, with high-quality components and materials.

The analysis board

BR-A03P-Z4 analysis board

IMQ Certified
Security grade 3

Multi-zone digital analysis board

All SERIE A03 PRO detector models are managed by a single electronic processing board, the BR-A03P-Z4. This is a multi-zone digital analysis board that uses high-efficiency filters to process signals from detectors and generate alarm states.

Differentiated alarms by attack type

Pre-alarm
Break-in (low intensity shocks)
Breaking through (high intensity shocks)
Drilling/cutting (continuous vibrations)

Essential notifications

Sensor tampering (removal, cable cut)
Power fail (power supply anomaly)

4 communication channels

BR-A03P-Z4 has 4 communication channels, to each of which two sensors of the same type can be connected, for a total of 8 sensors. This architecture simplifies the creation of point alarm zones, consisting of one or two sensors installed on a single door/window or structure. This way you benefit from point identification while preserving the advantages provided by non-powered sensors.

Detection line mode

The only exception to the previous rule is given by the non-balanced detector SN-A03P-WLT, which can be used to create detection lines up to 10 sensors: each line occupies one of the 4 channels provided by the analysis board and can be managed as an independent alarm zone.

10 NC solid-state outputs

The BR-A03P-Z4 has 10 NC solid-state outputs (4 Break-in/Breaking through Alarm outputs, 4 Opening Alarm outputs, General Tampering, Insufficient Power) for connecting the system to an alarm panel.

To access the board's configuration and calibration functions, you need the DG-DEA-WF2 Wi-Fi dongle (see image above) and the related service app for mobile devices (see below).

The service app

Professional configuration from smartphone

The A03 PRO system comes with a service app, available for free download for iOS and Android mobile devices, which allows you to configure and calibrate detectors centrally, using a secure Wi-Fi connection. Unlike Bluetooth wireless technology, Wi-Fi covers much greater distances: this makes it possible to perform calibrations even from different rooms or floors than the one where the analysis board is located.

For each of the 4 channels you can:

Independently adjust sensitivity for weak shocks, strong shocks and continuous vibrations
Set the number of events that trigger the alarm (weak shocks and continuous vibrations)
Set the memory time for event counting (weak shocks)
Enable/disable anti-dilation mode (strong shocks)
View the intensity of signals perceived by sensors thanks to a real-time updated graphic bar

Regardless of the screen you are on, the app allows you to monitor in real time the status of all channels and know the specific alarm event thanks to the use of explanatory graphic icons.
