Bosch Small System Controller
The PRAESENSA public address and voice alarm system gets a new controller option, the PRA-SCS Small System Controller. This cost-effective alternative allows for optimization of the PRAESENSA system components to meet specific project needs, improving operational efficiency and reducing overall system cost. Particularly suited for mid-sized applications, the PRA-SCS Small System Controller offers more options to designing a tailored, value-oriented PRAESENSA solution across a wide range of installation sectors such as hospitality, education, retail stores and commercial buildings.
The Small System Controller oversees all system-related functions within an IP-based PRAESENSA system, including the routing of all audio connections between network-connected PRAESENSA audio sources and destinations. It handles calls, emergency alerts, collects device status information, and generates fault reports. Furthermore, it also plays back messages and tones stored on its flash memory and manages background music streams, business calls, and emergency calls based on priority level and zone occupancy. Equipped with an internal real-time clock, the controller can schedule events and features event time stamping, with support for Network Time Protocol (NTP) and automatic adjustment for Daylight Saving Time (DST).
Ideal for medium-sized installations
Identical to its larger counterpart, PRA-SCL, the PRA-SCS Small system controller delivers multi-channel audio and provides an easy-to-use browser-based control interface. DC‑powered from a multifunction power supply with an integrated battery backup, the controller fits both centralized and decentralized system topologies. System communication is based on OMNEO IP architecture over an encrypted IP network, ensuring robust security and data protection.
Connections to other system devices are established via the built‑in 5‑port switch, which supports the Rapid Spanning Tree Protocol (RSTP) and has an open interface for third-party applications. PRA-SCS can function as single system controller, as part of a redundant system controller concept for uninterrupted system availability, or even as subsystem controller in a multi-subnet system.
The PRA-SCS boasts the same powerful feature set as its larger counterpart but at a lower price point, making it particularly suitable for small to medium-sized installations due to two restrictions. It can assign a maximum of six amplifiers for up to 48 zones when used with the PRA-AD608 amplifiers. Although it supports the same eight external Dante/AES67 input/output channels, including encryption and decryption, it does not offer the additional 112 static Dante input channels that are available for the larger controller. The PRA-SCS Small System Controller becomes a compelling choice in scenarios where these constraints don't play into the project requirements.
