Description
The Bosch PRA-CSBK basic call station kit is an open frame call station to create dedicated full custom operator panels for PRAESENSA Public Address and Voice Alarm systems. It has the same functionality as the PRA-CSLW, but without LCD user interface to facilitate easier mounting in operator desks or in wall‑mounted fireman’s panel enclosures. The Bosch PRA-CSBK comes with a hand‑held supervised omni‑directional microphone for close talking with press‑to‑talk button and a small monitor loudspeaker.
The kit has a CAN‑bus interface on RJ12 to a PRACSEK Call station extension kit for connection of selection switches and status indicator LEDs, or to connect to a full custom control board with switches and indicators. The interface is compatible with the PRA-CSE and one to four of these devices can be connected. The kit only requires a connection to an OMNEO IP‑network with Power over Ethernet (PoE) for communication and power supply combined. It can be configured as business and emergency call station. The PRA-CSBK is considered a component that must be installed in a final product. The final product must be reconfirmed to meet applicable EMC directives.
IP-Network Connection
- Direct connection to the IP‑network. One shielded CAT5e cable is sufficient for Power over Ethernet, audio and control.
- For dual redundancy of network and power connection, a second shielded CAT5e cable can be connected.
- Integrated network switch with two OMNEO ports allows for loop-through connections to adjacent devices (at least one must provide PoE). Rapid Spanning Tree Protocol (RSTP) is supported to enable recovery from failing network links.
