Detectomat M1BT DC 510/520 Control Panel Loop Interface Module

The M1BT is a microprocessor-controlled loop interface card installed in DC 510 and DC 520 control panels. It manages 256 devices from the D-Loop series on a single card and maintains communication without interruption even in the event of a short circuit. In expansion projects where the number of loops needs to be increased, the card is added while preserving the existing enclosure. This way, a cable fault in one section of the line does not disable all detectors.
