Nortech CRC200S Quick Installation Manual

Scope
This guide provides the basic instructions for installing, configuring and adding sequentially
numbered cards to the CRC200S Controller. Refer to the User Guide for detailed information on
using the CRC200S.
Fitting the CRC200S
Release the front cover from the main unit by pressing the securing buttons at the base of the unit
while you lift off the cover from the bottom (hinging the cover at the top).
Carefully unplug the ribbon cable linking the cover to the main unit (avoid pulling or bending the
ribbon cable). Completely remove the front cover.
Fit the unit to the mounting surface using the 2 keyhole slots and 2 mounting holes in the back
plate. Use 4 appropriate screws or nuts/bolt (M4) according to the type of mounting surface.
After wiring the unit, support the cover with one hand and carefully re-insert the end of the ribbon
cable into its socket. Refit the cover by engaging the top of the cover with the top of the housing
and hinging in the bottom of the cover until the securing buttons are fully engaged in the housing.

Reader Voltage Settings
Each of the two reader interfaces includes a power supply output that can be individually set to
either 5V or "supply voltage" to match the requirements of the connected reader. The voltage for
each reader is set on a jumper to the left of the corresponding terminal block. To avoid damage to
the readers, you must set the correct voltage for each reader before applying power to the
CRC200S. For use with 12V readers, the power supply to the CRC200S must be 12VDC.
If you are in any doubt about the output voltage to the reader, apply power to the CRC200S without
connecting the readers and measure the voltage across the reader +ve and -ve connector pins.
