A weatherproof, rugged cast aluminium siren with a very powerful low frequency output. Ideally suited for use in factories, refineries, quarries, construction and industrial sites, as well as both underground and surface nonfiery mining. Thermal cut out protected.

Very durable all weather proof siren manufactured with the highest quality cast aluminium with a very powerful low frequency output. Ideally suited for use in factories, refineries, quarries, construction and industrial sites, as well as both underground and surface non-fiery mining.

A robust, rugged cast aluminium siren with a very powerful low frequency output. Ideally suited for use in factories, refineries, quarries, construction and industrial sites, as well as both underground and surface non-fiery mining.

Precision machined aluminium body with all weather enclosed, continuously rated motor. Ideally suited for use in factories, refineries, quarries, construction civil defence and industrial sites, as well as both underground and surface non-fiery mining.

All weather enclosed motor is ideally suited for outdoor use. This siren would be used for audible warning at refineries, oil rigs, in the event of fires and open-cast mining operations. This precision machined unit produces a powerful dual low frequency sound that is ideal for long distance signalling.

Long Range Electronic Siren – Bono Stand Alone (130db)

The BONO electronic siren, available at an optimal price, provides high-quality sound distribution in the threatened area. It is mainly designed as separate, locally-controlled warning equipment. However, it can be also used for creating simple warning systems. It enables the creation of systems with output of 300 – 1,200 W.

Huge tsunami tidal waves caused by tectonic movements under the sea level have proved, especially in the last decades, to represent a high risk for many islands as well as continental shores. Early warning and announcing systems consisting of a forecasting and monitoring subsystem with sensors and from an acoustic warning subsystem represented mainly by electronic sirens are able to achieve substantial elimination of casualties.

Solution description

In several countries threatened by tsunami they have already built a forecasting and monitoring subsystem for monitoring of natural phenomena and this system is administered by specialised institutions. Proposed solution consists in addition of an acoustic warning subsystem (Pavian electronic sirens network) and interconnecting it with the forecasting and monitoring subsystem. With regard to the need to cover large and broken-relief territories, the satellite data transfer was assessed as the most suitable control and communication method. If necessary, it can be supplemented with an alternate radio signal or a GPRS signal from ground-based transmitters. If the siren is equipped with local control, it can be used not only for warning inhabitants against an impending danger, it can also be used by rescue forces directly on site to perform rescue works and communicate on the affected territory. Similarly created warning system can also be successfully used in case of danger of other natural phenomena such as tornado, fire, volcano eruption, or earthquake.
