The new Plena Voice Alarm system, manufacturers Bosch Security Systems say, meets requirements of IEC60849, the European standard for voice alarm systems.
Applications, it is claimed, include factories, offices, hotels, shopping malls, supermarkets, schools, and sports facilities.
Voice alarm systems can play a vital role, the firm says, in guiding people to safety during emergencies. The new product covers system supervision, spare amplifier switching, loudspeaker line supervision, digital message management, and an interface for a fireman’s panel. The system is based on the six-zone Plena voice alarm system controller. The system controller contains a 240-watt booster amplifier and a supervised digital message manager for up to 255 pre-recorded announcements or chimes that create a set of evacuation messages. Configurations can be extended to cover up to 60 zones using additional six-zone routers. Other dedicated elements include call stations and extension keypads. The voice alarm system is compatible with existing Plena equipment such as booster amplifiers and background music (BGM) sources, the makers add.
It is designed for plug-and-play installation, Bosch say. Elements are interconnected using standard RJ45 connectors and CAT5 cables. The new system, the makers add, is configured for specific applications using DIP-switches to set basic functions and a PC for more advanced features. A range of EVAC-compliant Bosch loudspeakers and accessories is also available.
