Technical characteristics

  • PR 4512 runs Bluetooth 4.2, and requires a smart device with 4.0 or newer.
  • PPS is compatible with iOS and Android devices.
  • The PR 4512 automatically detects the device setting on the connected PR 4000 and 9000 device.
  • An internal battery energizes the 4512 real-time clock for at least 2 years, should the 4512 remain de-energized.
  • Typical data logging capacity is more than 30 days at 1 second intervals.
  • Easy to read dot matrix LCD display.
  • Fast pairing or safe pairing via two-factor authentication.

Mounting / installation / programming

  • Mounting in Zone 2 / Div. 2.
  • The 4512 can be moved from one device to another. The individual system 4000/9000 device configuration of a transmitter can be saved and downloaded to subsequent transmitters.
  • Programmed parameters can be protected by a user-defined password.
  • When mounted on devices that are installed upside down, a menu selection rotates the 4512 display 180 degrees and reverses the up/down button functions.
  • All data, including configuration, data log and event log from a PR 4000 / 9000 device can be transferred to a PC using the PR 4590.
