1 Introduction
The VR20M-MFand VR50M-MF are mullion mount card readers with modern security over OSDP and
support for the traditional Wiegand protocol. When installed as part of a secure system, the
communication from the reader or the controller they are connected to cannot be compromised. The
readers are made of hard wearing materials and will endure most weather conditions. The readers are easy
to mount and can be mounted on a flat surface. The readers can be cleaned with most kinds of domestic
detergents. All readers have a multicolour light frame. The VR50M-MF has a keypad for pin code.
