Just delivered a fully assembled turnkey Bosch Plena Voice Alarm System to our client for their overseas project. We proposed the Bosch Plean VAS (Voice Alarm System) for its rugged reliability, simple operation and rich feature set. The system is comprised of LBB1990 (PA Controller), LBB1992 (PA Routers) and LBB1938 (Power Amplifiers). The system also include background music capabilities using multifunction and dual output CD/MP3/USB/AM/FM Radio player. We also included a weekly programme digital programmable timer for break chime activation. The standard suite of evacuation messages were preloaded into the memory and can be activated by link to fire alarm or by using the included message activation buttons.
