Q Jeramy Gratton • 11/02/2026, 3:55:43 PM Can the bosh ds160 trigger an door opeing event connected to an infinias s-eid32 controller?

A 11/02/2026, 4:12:32 PM The main relay on the Bosch DS160 is typically wired in-series (COM, NC) with a Fail-Safe lock to cut power directly at the lock allowing for an exit. The secondary relay (COM, NO) could be used to trigger a Request-to-Exit input on a 3rd party access controller which would also allow for a door release.
