HARDWARE INSTALLATION
INTRODUCTION
The S300-DIN-RDR2SA module provides interface control for access and security devices
associated with one or two doors.
NOTE
Throughout this manual the S300-DIN-RDR2SA module is also referred to
as the RDR2S-A.
The key features of the RDR2S-A include:
Wide range nominal voltage for power source (+12 to 24VDC, 16 to 24VAC)
Support for RS-485 bus communications at 9600 or 19200 (Auto baud rate
detection 9600/19200 baud)
Two-door access control input/output interface, each door’s interface consisting of:
- Supervised door monitor switch input, normally open or normally closed,
based on wired configuration

- Supervised auxiliary access or exit request switch input, normally open
- Supervised tamper and spare inputs
- Wiegand Data0 and Data1 interface
- Door strike relay, SPDT (Single Pole Double Throw)
- Alarm shunt relay, SPDT
- Red lamp driver and green lamp driver (open collectors)
- +12VDC 250mA reader power supply
Also, the following inputs are shared by both interfaces (one per unit):
- Calibration resistor input
- Supervised tamper and power fail inputs
APPLICATION
The S300-DIN-RDR2SA module is an interface for the CK722, CK721, and CK720/CK705
controllers using standard RS-485 communications. It supports up to two doors per unit.
The RDR2S-A provides the ability to configure supervised 4-state inputs and unsupervised
2-state inputs. When used with CK722 and interfacing to a single door, the unused points can
be configured as general purpose input/output (I/O) points, possibly eliminating the need to
purchase additional I/O modules for certain installations.
The RDR2S-A provides power for the card reader hardware. It does not provide power for
door locking hardware.
INSTALLATION
Unpacking the Equipment
Carefully inspect the S300-DIN-RDR2SA shipping containers as soon as you
receive them (with the delivery agent present). Some shipping companies want to
have an agent present when a damaged container is opened. If a container is
damaged, open it immediately, inspect the contents, and have the agent make note
on the shipping document. Check the purchase order against the packing slips to
ensure the order is complete. If the contents of a container are damaged in any way,
notify the carrier and your Johnson Controls representative immediately. Report any
discrepancies to your Johnson Controls representative. Save the packing materials
for possible return shipments.

Tools Needed
Small, straight-blade screwdriver for securing wires in the terminal blocks.
Acceptable Switch/Relay Contact Inputs
Use only fine gold, gold flash, or reed switch/relay contacts. Do NOT use silver,
coin silver, or nickel contacts, as these may oxidize and degrade over time, thereby
causing the circuit to fail.
MOUNTING
The S300-DIN-RDR2SA can be mounted on a flat surface, DIN rail, or in a Johnson
Controls’ approved enclosure (for example: S300-DIN).
For information on mounting the S300-DIN-RDR2SA in an enclosure, refer to the manual
provided with the enclosure.
DIN Rail Mounting
³To mount an RDR2S-A module on a DIN rail:
1. Fully extend the white clips located on the bottom of the module.
2. Hook the module on top of the rail.
3. Push in the clips.

³To remove a module from the DIN rail:
1. Pull down the clips at the bottom of the module.
2. Pull the bottom of the module out and lift it up.
Flat Surface Mounting
³To mount an RDR2S-A module on a flat surface:
1. Make sure no connectors obstruct access to the clips on the bottom of the
module. If necessary, remove the connectors.
2. Fully extend the bottom clips.
3. Mount the module to the surface with mounting screws.
4. Replace the connectors, if previously removed.

Line Voltage Information
If the facility is located in an area where power lines are subject to frequent lightning
strikes, verify with the electric company that the building transformer is equipped
with surge protectors. These, as well as a “crowbar” type of protection, can be
installed at the main service entrance if the building transformer is not equipped
with lightning protection.
While lightning is one cause of power line transients, others can be internal or
external to the building environment. The general application of transient surge
suppression is low-cost insurance to ensure long life of the equipment being
installed.
DESCRIPTION OF SIGNALS
All interface signals are connected via plug-in connectors. For a description of the
RDR2S-A I/O interface signals, see “Input Point Signals” on page 18.
