Introduction
The Protege Half DIN Rail 2 Door Reader Expander extends the number of card reader inputs on the system by 2
or 4 when using multiple reader mode, the number of inputs by 8 (four inputs used for door monitoring and
control) and the number of outputs by 8.
Flexible module network architecture allows large numbers of modules to be connected to the RS-485 module
network. Up to 250 modules can be connected to the Protege system in any combination to the network, over a
distance of up to 900M (3000ft). Further span can be achieved with the use of a network repeater module.
