The Mercury Security Corporation panel for which the Mercury driver was created is the EP1501. This controller provides door control and networking capability (Ethernet) as a component in a complete access control system.

A third-party access program called Open Options manages the Mercury panels in the access control system. This program communicates with NiagaraAX through a Mercury panel. The two software programs do not communicate directly.

On the Mercury side, a portal is a door that is controlled by a Mercury EP1501 panel. With the Niagara Mercury driver, the access information monitored by each Mercury panel can be configured to manage building devices, such as turn lights on and off, turn the HVAC on and off, etc.
