Mercury M5-2SRP

M5-2SRP is a multi-device interface panel for the replacement of the Casi 2SRP reader control device. As with the entire Mercury M5 Bridge family of controllers, the M5-2SRP is built with a matching form factor to the Casi Micro5 line of access control hardware allowing a fast “screwdriverless” change over and easy migration of a Casi client infrastructure to any Authentic Mercury software partner. Built to provide the ability to control access for two openings, this panel offers support for 2 readers capable of being individually configured for Wiegand, Magstripe, F2F or Supervised F2F card reader protocols. Additionally, the M5-2SRP has the capability to monitor the door position, manage the door locking hardware and request to exit devices, with an auxiliary output available for each reader. Each legacy enclosure will support up to (6) M5-2SRP’s.

Application Notes

The M5-2SRP is an integral component in the Mercury M5 Bridge family approach to migrate any Micro5 hardware legacy to the flexible, feature rich Mercury access hardware. This ensures the customer an Open future based on Authentic Mercury controllers.
