Consultants, system integrators, and installers working on expansion and retrofit projects increasingly face tree and star-shaped loudspeaker line topologies, as well as existing infrastructures that cannot be looped through but still need to be supervised. Traditional loudspeaker line supervision methods such as impedance measurement are not always reliable and therefore unsuitable for high-safety sites such as power plants and hospitals, where robust supervision is essential.
To enable reliable supervision and fault detection, Bosch has expanded its PRAESENSA IP-based public address and voice alarm system with the End-of-Branch device, developed to support supervised multi-branch loudspeaker lines.
