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.
ADDITIONAL RESOURCES
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

●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 FAIL SAFE AND FAIL SECURE LOCKING HARDWARE
Fail safe and fail secure are ways of configuring locking hardware:
●Fail safe hardware unlocks when power is interrupted
●Fail secure hardware locks when power is interrupted

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.
