Safety and comfort with proven products
Ship loudspeaker and alarm systems are part of the safety concept on cruise ships and other ships.
Guarantee safety with Bosch Praesensa
We have been using Bosch products for many years to create a pleasant atmosphere for cruise ship passengers while simultaneously guaranteeing their safety in the event of an evacuation. Bosch Praesensa is an IP-based system and uses an intelligent power supply concept with integrated redundancies, making it ideally suited for centralised and decentralised topologies. It is an extremely flexible system as it provides a practically unlimited number of zones and a large number of audio channels with local sources and volume controls.
The system can be easily connected to fire alarm, weather alarm, security alarm and other third-party systems. Praesensa complies with every convention for international trade ships, and is recognised by every important seafaring nation. It is certified in accordance with SOLAS (“Safety of Life at Sea”), the most important safety standard in maritime transport, and offers standard ship alarm sounds. The system currently has “type approval” from DNV-GL, one of the most common classification companies on the market.
Praesensa – IP-based with OMNEO
Praesensa meets the following requirements:
- Addressable EVAC zones corresponding to the ship’s fire compartments
- Fire alarm system interface
- A redundant A-B system configuration ensures that emergency messages will not be missed, even in the event of a partial system failure
- As it can be used to make announcements in non-emergency situations, an expensive separate communication system is unnecessary
- Flexible volume control for background music with an appropriate interface for the ship’s entertainment system
Praesensa is a fully-digital, IP-based solution that meets the requirements for ships when it comes to PA systems, vocal alarms and background music. The flexible network topology means the system can be accessed all over the ship. The zones can be freely divided into deck, cabins, engine room and other functional areas.
Ships require different system structures.
Freely scalable power amplifiers efficiently meet specific performance requirements in the individual zones. Various music sources can be connected to the system inputs and routed into the various public areas and event spaces. Audio signals can be routed from the entertainment system to the Praesensa using the OMNEO interfaces. Having local touch screens in certain areas of the ship (e.g. theatre, spa, gym, etc.) is possible, and will increase the comfort of the guests and crew.
The digital signal processing (DSP) system integrated into the Praesensa amplifiers ensures a comfortable PA system volume regardless of ambient noise, and guarantees extraordinary clarity for announcements and evacuation messages. The amplifiers are extremely efficient.
