S321-IP HARDWARE INSTALLATION
The S321-IP controller communicates with the host via Ethernet. It supports up
to two doors per unit and allows you to configure supervised 4-state inputs and
unsupervised 2-state inputs. The S321-IP controller provides power for the card
reader hardware; it does not provide power for the door locking hardware.
ABOUT THIS DOCUMENT
This document describes S321-IP hardware installation, basic operation, and
maintenance procedures. It is divided into the following sections:
•Unpacking the Equipment on page 1
•Tools Needed on page 1
•Mounting on page 2
•Description of Signals on page 5
•Cable Requirements on page 7
•Basic Commissioning on page 10
•The S321-IP User Interface on page 16
•Technical Specifications on page 19
•Maintenance on page 20
UNPACKING THE EQUIPMENT
Inspect the S321-IP shipping containers as soon as you receive them, with the
delivery agent present. 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, 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.
Your package should contain the S321-IP controller, connectors set, a CD
containing a set of user documentation, and this manual.
TOOLS NEEDED
Use a small, straight-blade screwdriver to secure wires in the terminal blocks.

MOUNTING
You can mount the S321-IP controller on a flat surface, DIN rail, or in a
Johnson Controls’ approved enclosure (for example: S300-DIN).
For information on mounting the S321-IP in an enclosure, refer to the manual
provided with the enclosure.
To mount an S321-IP controller on a flat surface:
1. Fully extend the white clips located on the top and bottom of the
controller. You may need to remove the connectors.
2. Mount the controller to the surface with mounting screws.
3. Replace the connectors, if previously removed.
To mount an S321-IP controller on a DIN rail:
1. Fully extend the white clips located on the bottom of the controller.
You may need to remove the connectors.
2. Hook the controller on top of the rail and push in the clips.

3. If you need to remove a controller from the DIN rail, reverse the
mounting sequence (pull down the bottom clips, then pull the bottom
of the controller out and lift it up.)
Power Source Requirements
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.
Lithium Battery
The S321-IP contains a lithium battery that is used for realtime clock
backup. The lithium battery is shipped from the factory charged and
operational.
If there are no power outages, change the battery every five years. If a
power outage occurs, the battery life is approximately 30 days. Replace
with Panasonic part number CR2025 or equivalent.
Parameter Value
Power 24 W
Input voltage +12 to +28 VDC; 16 to 28 VAC
Nominal voltage +12 to +24 VDC; 16 to 24 VAC
Current 1 A at 24 V; 2 A at 12 V
Class 2 transformer (optional) See step 8 on the Underwriters Laboratories Compliance
Verification Sheet at the beginning of this manual.

IMPORTANT: After you replace the lithium battery (recommended every five
years or after extended use), verify that the realtime clock is correct; otherwise,
you may need to adjust the time.
To replace the lithium battery:
1. Disconnect the 24 VDC power from the S321-IP.
2. Unscrew and open the plastic enclosure.
3. With a narrow (1/8 in.) blade, carefully pry up the battery until a
portion of the battery is out of the plastic holder.
4. With your free hand gently move the battery out of the holder while
keeping the battery pried up.
5. Dispose of the old battery according to local requirements.
6. Insert the new battery into holder.
IMPORTANT: The lithium battery is polarized. Ensure the side marked ‘+’ faces
out (that is, towards you).
7. Close the plastic enclosure and secure it with the screw.
8. Re-connect the power to the S321-IP.
CAUTION: Risk of Explosion.
Replace the battery with a lithium battery of the same type and
voltage rating. Dispose of the used battery in accordance with local,
national, and regional regulations. Failure to replace the battery with
one of the same type and voltage rating may result in an explosion
causing personal injury and property damage.

Wiegand Input
Description of Signals – DATA0 and DATA1 from each reader,
complying with the Wiegand interface specification.
Reference – These signals are referenced to logic ground (COM).
Protection – Each signal has a 6 V transient voltage suppressor between
it and COM.
Input Points
Description of Signals – The following are internally pulled up inputs:
The allowable voltage range for these signals is 0-12 VDC.
Reference – These signals are referenced to their associated COM input.
Protection – Each signal is protected with series resistors and dual
clamping diodes.
External Circuits – 4-state operation requires two external resistors and
switch circuit connected between an input point and COM. 2-state
operation requires an external switch connected between an input point
and COM. For wiring details see Wiring Input Devices on page 8.
Output Points
Description of Signals – The following are open collector outputs, with
voltage range for these signals of 0-24 VDC, limited to 50mA:
IMPORTANT: These open collector outputs can be damaged by alternating
current (AC) potentials as low as 1 VAC. Connect the LED outputs only to direct
current (DC) loads up to 24VDC.
