The Cypress Suprex® Reader-Extender SPX-1300 is a communication link which connects a reader to an access controller using existing RS-485 wire, allowing readers to be installed at sites farther from the controller, without buying a second control panel.
A Suprex is a pair of units: The Remote unit connects to the reader, and the Central unit connects to the controller. The typical range for the SPX-1300 is 10000 ft. / 3048 m.
Suprex RS-485 models (SPX-1300, SPX-7500) also provide high immunity to electrical noise under adverse conditions, such as elevator installations.
Other Suprex models connect the reader to the controller wirelessly, or connect using available fiber optic or Ethernet cable.
