The Loop Drive Booster (LDB) is the heart of the Loopdrive system. This device drives up to 200 FIM’s over a dual-core cable. A single LDB can pass 800 W of audio signal from an amplifier and injects at the same time DC to the loop for powering and managing FIM modules. One amplifier channel can be split into multiple LDB in parallel, creating multi-loop with individual surveillance for multi-zone paging applications.
The LDB clicks on a DIN-rail that provides DC-power and accommodate for the RS485 data connection and GeneralFault contact to a maximum of 32-LDB’s on a single DIN-rail. Front buttons and indicators allow for quick access to the various functions and indications of the Loopdrive system.
SNIFFER is not only visualizing the various commissioning procedures but also provide streamlined methods for faultfinding and device allocating without the direct need for a digital communication protocol over the 2-wire audio line’s. It fulfills the user’s needs and expectations by far.
