Bosch Security

Efficient 4‐channel power amplifier • Transformerless, galvanically isolated, 70/100 V outputs, with a total loudspeaker output power of 600 W. • Flexible partitioning of the available output power across all amplifier channels to use it effectively, significantly reducing the amount of required amplifier power in a system.

Independent mains power supplies • Three fully independent 48 VDC power supplies for up to three amplifiers. • One 24 VDC output for a system controller or auxiliary device. • All power supply outputs have double connectors for A/B dual redundant wiring to the connected loads.

PRA-CSLD Desktop LCD call station 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.

Efficient 8‐channel power amplifier • Transformerless, galvanically isolated, 70/100 V outputs, with a total loudspeaker output power of 600 W. • Flexible partitioning of the available output power across all amplifier channels to use it effectively, significantly reducing the amount of required amplifier power in a system.

Business operation • Connection of up to four PRA-CSE extensions, each with twelve buttons. The buttons can be configured for various functions, but they are especially useful for zone selection, giving a clear overview of accessible zones and the LED indicators for each button show the status of the respective zone (like being selected, occupied or at fault).
