Mercury EP1501/LP1501 Intelligent Controllers

The EP1501 and LP1501 are edge-capable intelligent controllers that are expandable for up to 8 downstream SIO controllers and up to 16 MR51e or MR62e network ready door controllers (for a total of 16 doors/ openings).

Built on the Authentic Mercury platform, the feature-rich EP1501 and LP1501 provide a small footprint, cost-effective dual card reader panel for controlling a single opening. Easy installation with Power over Ethernet (PoE) makes the high performance, Ethernet-ready EP1501 or LP1501 a top choice for a single-door controller.

Once configured, the intelligent controller functions independently of the host and can control access and manage sophisticated device processes (such as anti-passback and point linking) both onboard and downstream of the EP1501 or LP1501 without host intervention.

Offering powerful flexibility, the Mercury EP1501 and LP1501 can interface with an array of reader technologies for a single opening. The controllers support separate in/out readers and technologies: Wiegand, clock and data, RS-485, OSDP, magnetic stripe, F/2F, Supervised F/2F Readers, keypads, LCD, and biometrics.

The EP1501 and LP1501 provide the versatility and reliability needed to deliver powerful innovation for system success and at the system’s edge when needed.

Application Notes

The EP1501 and LP1501 seamlessly interfaces a single opening to a larger system (up to 16 openings) for easy expansion. Providing all of the intelligence and functionality of the Mercury family of controllers, the EP1501 and LP1501 are PoE capable and set the standard for powerful, reliable performance; all at economical price points.
