The BSM product family from EES is one of the most comprehensive fault annunciator series available on the market and is characterized by a large number of options that can be ordered to adapt the annunciator with up to 192 alarms to the respective tasks on site.

Further options and corresponding extensions have been added since last year:

Firstly, the number of function inputs will be doubled, from the previous 2 to 4 inputs, more functions can be triggered or parameterized. In addition, 2 horn priorities can now be assigned to the collective alarms, which can trigger a horn or a bell for important alarms, for example. These settings are either permanently assigned in the basic BSM-C version or can be freely parameterized in the BSM-P version.

The latest version 3.4 adds another highlight to the BSM fault annunciator, the self-generated signal voltage. In the field of energy technology, different voltage ranges are often used, which are supplied from different sources and therefore have different potentials. Redundant power supply units can already be used in the BSM fault annunciator for the actual operating voltage, covering AC or DC from 24-60V or 110-250V, for example, but the signal voltage may therefore lie outside the redundant voltage range.

The new “S” option for the self-generated signal voltage can now be ordered for this purpose, which provides a 24V DC supply for up to 48 signal inputs and the 4 named function inputs. In the event of redundancy, e.g. switching from primary 230V AC to secondary 60V DC, the BSM will be able to reliably display and process all alarms.

Finally, the parameterization program has also been adapted from version 3.4. In addition to a visual refresh, the labeling can now also be customized by allowing the font size and font per channel to be freely edited. This is particularly useful for longer labels. The new version automatically recognizes new and previous types and adjusts the parameterization options accordingly.

This further rounds off the BSM fault annunciator package and many of the extensions are available free of charge.
