PRA-EOB
PRAESENSA End-of-Branch Device
Compact end-of-branch supervision device for branched PRAESENSA loudspeaker lines on 70 V or 100 V, detecting open-circuit faults in the amplifier without extra wiring.
Description
The PRA-EOB extends PRAESENSA line supervision to loudspeaker lines that split into branches. Fitted at the end of each branch, it lets the amplifier detect open-circuit faults on every branch without additional wiring.
It works with 70 V or 100 V loudspeaker lines and can be mounted in several ways.
Trinity Solutions supplies, programmes and commissions Bosch PRAESENSA public address and voice alarm systems across the UAE, including integration with fire alarm, IP telephony and BMS.
