Battery Safety Terminal

Battery Safety Terminal (BST)

The Battery Safety Terminal (BST) is technically identical to the one used in MRS systems.

If the ISIS system detects a crash of sufficient severity, the ignition stage of the BST is triggered by the B-pillar satellite, right (SBSR).

A small quantity of solid fuel electrically and mechanically cuts the starter and alternator line from the positive terminal of the battery. This prevents possible short circuits in the engine compartment.

A separate vehicle electrical system connection through the Power Module ensures that the remaining vehicle circuit retains its function when the BST is triggered.




This ensures the operation of all the important functions such as lights, hazard warning lights, telephone emergency call, etc..
