MRRE-4

GENERAL INFORMATION

The MRRE-4 receiver was designed to be connected to access control central units as a radio reader. The code received
from a transmitter is re-sent to outputs corresponding to the channel number and according to the format and
protocol selected by means of the programming dipswitches.
Formats available at the outputs are those most commonly used in access control systems and allow to interface the MRRE-
4 receiver not only with all PRASTEL control units, but also with the majority of the control units of the market.
