The DHI-VTM416 is an elevator control module that can manage permission controls for up to 16 floors. The DHI-VTM416 can scale to control up to 128 total floors by cascading 7 additional DHI-VTM416 programs as sub-mode. The module supports the RS-485 interface, two alarm outputs, and 6 alarm inputs. There is also an emergency release via the alarm input to have all floor access unlock in the case of a triggered alarm. The module can summon elevators to the VTO floor when used with a Dahua VTO.
