New LSNi voice sounder

September 2013 Fire & Safety, Products

With the introduction of the new LSNi Voice Sounder, Bosch now offers a standalone and uninterruptible voice sounder. The LSNi Voice Sounders combine sounder signals with a clear, synchronised voice message to improve the communication to people who need to be warned of hazardous situations. Clear and understandable messaging reduces the time taken for those at risk to recognise that an emergency exists.

The major advantage of the new LSNi Voice Sounder is its adaptability to customer´s requirements. With 32 pre-programmed signals and voice messages in seven different languages the device is easy to individualise and to adapt to the customer’s needs.

With the help of an installed database, the sounder can be flexibly equipped with individual recorded information. Even unique customer requests relating to the language or the text of the message are possible. In this case and to meet the highest quality demands, the customised messages get professionally recorded and supplied to the customer.

For locations with demanding safety requirements, uninterruptible voice sounding is an essential feature. Uninterruptible means that whether a T-tap interruption, one cable interruption, or even two cable interruptions occur in the loop, the sounder remains active. To activate this feature, an industrial high-performance battery with a life time of 10 years is needed and can be ordered separately. Besides the fact that sounders of the same LSN loop and with the same message always provide immediate synchronisation, the battery allows the sounder volume to remain constant, even in the case of voltage drop.
