As well as having a modern, small and discreet design the KEY-K01, KEY-KP01 and KEY-KPZ01 have a choice of non-prox (K), prox (KP) or prox with zones (KPZ). The prox keypads have connections for an external prox reader to be connected in addition to the internal prox. To add greater flexibility to the KEY-KPZ01 you can select the option of having two zones on board for an even faster connection of zones.
