If you're reading this, you probably already run Mercury hardware. A board failed and you need a replacement fast. Or you're adding doors to an existing system and you already have the licensing.
The Mercury MP1502 is a 2-door cyber-secure intelligent controller used in commercial access control systems. It manages door locks, card readers, and credentials for platforms like Genetec Security Center, Avigilon Alta, and Lenel OnGuard, and can expand to control up to 64 doors via RS-485 downstream panels. It is the current-generation replacement for the EP1502 and LP1502.
Board down? Doors not working? If this is an emergency replacement, you can skip the reading and order now. Orders before 2 PM ET ship same day. Overnight delivery is $30 flat. Every board comes with a 1-year guarantee.
Scenario 1: Failed Board — Doors Are Down. Your EP1502, LP1502, or older Mercury controller died. Two doors aren't working. Order an MP1502 with overnight shipping ($30). It arrives tomorrow. Add Standard Pre-Programming ($49) and give us your platform and network details in the order notes.
Scenario 2: Adding Doors to an Existing System. You're expanding — new wing, new floor, new building — and your access control system needs to grow with it. Order an MP1502 and skip the integrator hardware markup.
Scenario 3: Upgrading Older Mercury Boards. The MP1502 is a drop-in replacement for both the EP1502 and LP1502. Same wiring, same door count, same expansion capability — with significantly better security.
Standard Pre-Programming ($49): Tell us your access control platform and network details in the order notes. Board arrives ready to rack and connect.
Premium Remote Programming ($249): Everything in Standard, plus a scheduled one-on-one Zoom session after the board arrives.
