Openpath Access Control System Installation Guide

GETTING STARTED

This Installation Guide explains how to install and configure Openpath Smart Hubs (ACUs) and
Openpath Smart Readers as part of an Openpath Access Control system.

For more information, refer to the Smart Reader Data Sheet and Smart Hub (ACU) Data Sheet.

PRIOR TO INSTALLATION

Prior to installing Openpath hardware, it is assumed that you have performed a customer site
survey and have determined the following:

●How many entries need to be configured (e.g. doors, gates, and/or elevator floors)
●Whether you’re using legacy wiring or new wiring
●What kind of electronic entry mechanisms, Request to Exit (REX) mechanisms, and door
contact sensors will be used and their power requirements. If your locking hardware requires
24V DC, either use the Smart Hub ACU with included 24V power supply (SMART
HUB-ACU-4WDP) or use a separate 24V supply.
○NOTE: The Smart Hub ACU with 12V power supply (SMART HUB-ACU-4W) supports up
to 2A for locking hardware.
●Whether you’re providing backup batteries for the ACUs. See SELECTING A BACKUP BATTERY.
●Whether you’re supporting a legacy access control panel. See WIRING TO LEGACY PANELS.

Installation

NETWORK REQUIREMENTS

An Ethernet connection with DHCP must be used to connect the ACU to the Local Area Network
(LAN). You also need to configure firewall settings to communicate with the Openpath system.
Openpath uses the following outbound ports:

●TCP port 443

Version 1.2
© Openpath 2018
CONFIDENTIAL





●TCP port 80
●TCP port 8883
●UDP port 123

NOTE: If using an external DNS server, outbound UDP port 53 must also be open.
To support Wi-Fi unlocking from the mobile app, inbound TCP port 443 must be available from
within the LAN. Inbound port forwarding on the router, firewall, or NAT device is not required.

SELECTING A BACKUP BATTERY

While not required, Openpath recommends having a backup battery in the case of power outages.
The size of battery depends on your setup and how long you want to power the system.


Assuming a 12V power supply, a Smart Hub ACU configured with four Openpath readers and
locking hardware uses 4 Amps per hour. To keep the system running for 3 hours with all entries
engaged, you’d need a 12V 12A sealed lead acid (SLA) battery.

RECOMMENDED CONFIGURATION

Openpath readers and ACUs communicate via RS-485. The following wire types are compatible,
listed in the order of preference which impacts distance.

●Shielded CAT6A (recommended, additional two pairs can be used for sensors)
●Shielded CAT6
●Shielded RS485 w/22-24AWG (lower gauge, thicker wire is better)
●Shielded CAT5
●Unshielded CAT6
●Unshielded CAT5
●Shielded 22/6
●Unshielded 22/6





Ideally, use one twisted pair for GND and VIN (power) and one twisted pair for +B and -A (data).

For shielded wiring, we recommend that you connect only one side of the drain wire (the shield
around the wires) to the GND terminal on the ACU. Both the shield and the GND wire can share the
same GND terminal. Do not connect the other side of the shield to anything.

For reader installation, we recommend that you install a 1-Gang 20 CU box in order to flush-mount
the reader. Alternatively, the reader may also be surface mounted with the included back plate.

NOTE: For elevators, all relays must be on the same ACU. If you need more than four access
controlled floors, use our elevator expansion board.

WIRING TO LEGACY PANELS

To support a legacy access control system, install the ACU between the Openpath readers and the
legacy panel, with the ACU Wiegand port configured as output to the legacy panel. Replace low
frequency (LF) Wiegand readers with LF Openpath readers and high frequency (HF) Wiegand
readers with HF Openpath readers. In this setup, the legacy panel controls all locking hardware and
entry mechanisms while the Openpath system allows you to use the Openpath mobile app, Smart
reader, and Touch functionality.

LEGACY WIRING

Sometimes legacy wiring (unshielded and straight through, rather than shielded twisted pair, often
22-6) used with reader results in slower connections and dropped packets between the Openpath
Reader and Smart Hub. To remedy this, you can switch GND and VIN with +B and -A connections on
the ACU and readers to ensure the data pair (+B and -A) are using the alternate pair of legacy wires.

The Openpath ACU has several LEDs that indicate the following:

●POWER LEDs indicate that the ACU is connected to power
●The four RELAY LEDs indicate when the relays are activated
●The STATUS LED in the center of the ACU indicates that the ACU has been configured with
firmware
●The four READER POWER LEDs indicate that the ACU has output power enabled per reader

READER LEDS

The Openpath Smart Reader’s LEDs indicate the following:

●If the center dot quickly switches between multiple colors and outer ring quickly spins once,
the reader has just received power
●If all lights are off, the reader is not connected to power (check to see if the power wires are
swapped)
●If the center dot is flashing red, the reader is connected to power but cannot communicate with
the ACU (check to see if the +B and -A lines are swapped)
●If the center dot is solid blue, the reader is connected to power and can communicate with the
ACU, but has not been configured as an entry in the online portal
●If the center dot is solid green, and the outer ring lights up and spins, that means the reader has
been identified via the Control Center.
●If the center dot is solid white, then the door is locked
●If the outer ring is solid white, then the door is unlocked

RESETTING THE ACU

Soft Reset: To soft reset the ACU, disconnect power from the ACU, wait 10 seconds, then reconnect
the power.

WARNING: Only hard reset the ACU if absolutely necessary and if instructed by Openpath. This
will clear all of the data off of the ACU and will require reprovisioning, which requires having a
computer or mobile phone on the same network as the ACU.

Hard Reset: To hard reset the ACU, disconnect power from the ACU, hold down the ADMIN
BUTTON, reconnect power to the ACU, wait 20 seconds while still holding the button down, then

release the button. Wait 10 minutes before re-provisioning the ACU following the PROVISIONING
THE ACU steps below.

PROVISIONING THE ACU

Provisioning the ACU means registering it in the online portal and getting it up and running with
the latest firmware. ACUs are shipped already provisioned, but below are instructions for this
process in the case of RESETTING THE ACU.

To provision the ACU:
1. Connect the ACU to the Internet via Ethernet
2. Press the ADMIN BUTTON
3. On a computer or mobile phone on the same network as the ACU, go to
https://control.openpath.com
4. Log in with your administrative login
5. Go to Hardware > ACU Management
6. Locate the ACU on the list and click Register
7. A new window will open with instructions on registering the ACU. Click Yes to proceed.
