UA-Hub Wiring

Connecting the UA-Hub to LAN

Ensure the switch port that is connected to the UA-Hub is on the same LAN segment or VLAN as the UniFi Access agent. It must also support PoE+ or PoE++.

Connecting the UA-Pro to the UA-Hub

Use an Ethernet cable to connect the UA-Pro access reader to the UA-Pro PoE port on the UA-Hub.

Connecting the UA-Lite to the UA-Hub

Use an Ethernet cable to connect the UA-Lite access reader to the UA-Lite PoE port on the UA-Hub.

Connecting the G3-Flex to the UA-Hub

Use an Ethernet cable to connect the G3-Flex camera to the G3-Flex PoE port on the UA-Hub.

Connecting a Fail-Safe Lock with No External Power Supply

1. Connect the Lock Powered (NC) port on the UA-Hub to the (+) on the lock.
2. Connect the Lock Powered (COM) port on the UA-Hub to the (-) on the lock.

Fail-safe lock in this diagram refers to magnetic lock or electric bolt.

Connecting a Fail-Safe Lock with an External Power Supply

1. Connect the Lock DRY (NC) port on the UA-Hub to the (+) on the lock.
2. Connect the (-) on the lock to the (-) on the external power supply.
3. Connect the Lock DRY (COM) port on the UA-Hub to the (+) on the external power supply.

Connecting a Push Button

1. Connect NO on the push button to REL (+) on the UA-Hub.
2. Connect COM on the push button to REL (-) on the UA-Hub.

	Note: REL, REX, and REN all work the same way with push buttons.

Connecting a Motion Sensor

1. Connect NO on the motion sensor to REX (+) on the UA-Hub.
2. Connect COM on the motion sensor to REX (-) on the UA-Hub.
3. Connect V+ on the motion sensor to Line 12V (+) on the UA-Hub.
4. Connect V- on the motion sensor to Line 12V (-) on the UA-Hub.

	Note: REL, REX, and REN all work the same way with motion sensors.

Connecting a Siren

1. Connect AUX Powered (NO) on the UA-Hub to the (+) on the siren.
2. Connect AUX Powered (COM) on the UA-Hub to the (-) on the siren.

	Note: AUX powered output is 12VDC up to 0.33A.

The diagram below is an example; please consult the manual for your specific siren.

Connecting a Door Position Switch (Door Sensor)

1. Connect NC on the door position switch to the DPS (+) on the UA-Hub.
2. Connect COM on the door position switch to the DPS (-) on the UA-Hub.

Connecting an Automatic Door Opener with an External Power Supply

Please consult the manual for your specific automatic door opener. Use the AUX relays for the automatic door opener connection.

Connecting a Fail-Secure Lock with No External Power Supply

Connect the Lock Powered NO and COM ports on the UA-Hub to the NO and COM ports on the fail-secure lock, respectively.

Fail-secure lock in this diagram refers to electric strike.

Sample UniFi Access Diagram

	Note: The UA-Hub also features an additional PoE port for the UVC-G3-FLEX camera (optional).

Third-Party Accessories

Locks

Install each lock in its respective location. Each lock can be installed and connected to the UA-Hub in one of two ways:

• Dry connections
• Powered connections, 12VDC

Dry locks do not require power from the UA-Hub and are generally accompanied by their own external power or power adapter.

Powered locks receive 12VDC power from the UA-Hub.
