2 Mounting The Reader Expander is designed to mount on standard DIN Rail either in dedicated DIN cabinets or generic DIN Rail mounting strip. A section of this DIN Rail strip bas been provided as a mounting option. When installing the Reader Expander ensure that there is adequate clearance around all sides of the enclosure and air flow to the vents of the unit is not restricted. It is recommended to install the Reader Expander in a location that will facilitate easy access for wiring. It is also recommended that the Reader Expander is installed in electrical rooms, communication equipment rooms, closets or in an accessible area of the ceiling. Step 1 Hook the lower tabs under the bottom edge of the DIN Rail. Step 2 Push the enclosure against the DIN Rail mount until the upper tab clips over the upper rail. 2.1 Enclosure Removal The Enclosure can be removed from the DIN Rail mount using the following steps: Step 1 Insert a flat blade screwdriver into the hole in the tab at the top of the enclosure.

3 DC Power and Encrypted Module Network The Reader Expander incorporates encrypted RS-485 communications technology, and both module and network power are supplied by the N+ and N- terminals. N+ N- NA NB Network communications input from the Protege Integrated System Controller or previous Protege module Standard Communications Connection Connection of the communications and DC supply should be performed according to the diagram shown above. It is important that the N+ Network Communications Power be 12VDC supplied from an independent battery backed power supply unit such as the PRT-PSU-DIN capable of supplying the required voltage to all devices on the RS-485 network. Warning: • The 12V N+ and N- Communication input must be supplied from only ONE point. Connections from more than one 12V supply may cause failure or damage to the Reader Expander or device supplying network power. • The 330 Ohm EOL (End of Line) resistor provided in the accessory bag MUST be inserted between the NA and NB terminals of the FIRST and LAST modules on the RS-485 network. These are the modules physically located at the ends of the RS-485 network cabling.
