Stand Alone Electronic SirenThe first truly stand-alone siren Bono combines the possibilities of sophisticated electronic sirens with compact dimensions, and a battery backup. It can be used both in the exterior and interior, industrial areas and noisy production halls, open-pit mines, and in a variety of other areas. Bono can reproduce alert tones and voice messages from its internal memory, broadcast live from an external microphone as well as transmit audio signals from other external sources.

The electronics of the siren including a battery and 100W pressure loudspeaker is embedded in a resistant box made of Aluminium and stainless steel, while maintaining the low weight and minimum dimensions of the siren. A wide range of optional accessories is offered to communicate with, control, or to power the Bono siren using a solar panel. As standard, Bono is supplied with a big horn in the 100B version; however, upon request, it can also be supplied with a small horn in the 100S version.


By adding a solar pack as an option, Bono becomes completely self-contained, with no need for external power supply. Using a suitable activation method (e.g. by means of a satellite or sensors), Bono is a fully autonomous device usable anywhere – in a jungle during road construction or in a swamp of an openpit mine. In addition, there are various options of compatible sensors that can be connected directly to the siren.


A specially-shaped horn made of aluminium alloys and stainless steel in combination with a powerful 100 W pressure loudspeaker provides high-quality acoustic coverage of the desired area. A virtually infinite number of voice messages with their predefined priorities, interruptions, or combinations can be recorded, stored in and conveyed by the Bono siren equipped with the MiniAudiomodule (mAUD11).


eight binary inputs and two binary outputs
S232/RS485 interface
aBUS interface for other modules of the aSCADA® system
FFSK analogue modem support
Ethernet line interface (the optional module required)
WiFi/X-bee interface (the optional module required)
GPRS interface (the optional SmartBridge+GPRS modules required)

Auto Diagnostics

The Bono siren has a number of in-built self-diagnostic functions providing that customers opt for two-way communication between the siren and control centre. The battery status and systems functionalities can be monitored remotely by an operator, thus there is no need for a technician to be sent to the siren, which significantly saves the operational costs.
