Installation manual
View or download the installation manual for Access Controller Pro 2.You will need the following tools to complete installation:
- Flathead screwdriver
Step 1: Confirming kit contents
Before beginning, confirm the contents of your installation kit.
A. 1 x 8 pin, 3.5mm pitch KF2EDGK
B. 1 x USB 5V DC wall supply
C. 1 x 5 foot (1.5 meters) micro USB cable
D. 2 x 3M Stretch Release Adhesive
E. 4 x Cable labels
F. 1 x Puck Antenna
G. 1 x Ring Access Controller Pro 2 Device

Step 2: Installing plug-in terminal wire
- Turn off power at the source.
- Strip insulation to expose about 0.25 in (0.64 cm) of wire.
- Important note: Wire requirements are 18 - 22 AWG (American Wire Gauge).
- Use a flathead screwdriver to release the screws on the eight-pin terminal connector so the wire can be inserted.
- Place each wire in desired opening.
- Tighten the screws to hold the wires in place. Then, tug on the wires to make sure they are secure.
- Connect to desired access control terminals.
- Plug in the eight-pin connectors to their mating connector on the device.
- Use cable labels to identify wires appropriately.


Ethernet cable (if applicable)
Once wires are connected to the plug-in terminal, if an Ethernet connector is available, insert the Ethernet wire into the connector array. Then connect the puck antenna to the antenna port as a backup.
Power wire
- Device outside call box:Connect to power by inserting the micro USB plug on the DC power supply brick, and fold the "Do Not Unplug" sticker on power cable 1 to 2 inches (2.5 to 5 centimeters) from the wall supply.
- Device inside call box:Connect to power through seven and eight on the connector array. Positive and negative terminals are interchangeable (polarity agnostic). Place the "Do Not Unplug" sticker on the device without covering LED status lights or labels.
Step 3: Connecting the antenna
- Identify a knockout where the antenna wire will reach your Ring Access Controller Pro 2 installation location that is at least 0.5 in (1.27 cm) away from the wall.
- Unscrew the nut and remove the washer from the puck antenna.

3. Remove the knockout on the call box or junction box.

4. Insert the cable through the hole you made, ensuring the puck antenna is outside the call box or junction box.
5. Place the washer on the antenna mounting post inside the call box, and screw the nut to fix the antenna in place so it’s tightly mounted. Do not overtighten.
6. Attach the antenna connector to the device’s antenna port until it locks in place.

Step 4: Understanding LED and connection terminal indicators
POWER: A solid light next to “PWR” indicates the device is powered.
CELLULAR: The light next to “CELL” changes color to indicate cellular signal strength. It remains unlit when connected to Ethernet.
- A solid red light indicates no cellular coverage.
- A solid yellow light indicates low cellular coverage.
- A solid green light indicates good cellular coverage.
- A solid white light indicates the device is using Ethernet.
- A solid blue light indicates attempting to get cellular strength.
CONNECTED: A flashing light next to “CON” indicates the device has Internet connectivity.
RUNNING: A flashing light next to “RUN” indicates the device is running as programmed.
RECORDING: A solid light next to “REC” indicates device is in record mode and scanning for access credential only occurs while provisioning a fob credential.
DOORS: A solid light next to “DR1“ or ”DR2“ for two seconds indicates the respective door is opening at that time.

Step 5: Mounting Access Controller Pro 2
Device outside call box or existing junction box:
- Remove the liner on the 3M Stretch Release adhesive provided, and place it in the two recesses provided on the back of the device.

2. Drill holes or remove knockouts from the PVC junction box for wire and puck antenna mounting.
3. Clean the surface where the device will be installed with a surface cleaning solvent, such as isopropyl alcohol or heptane.
4. Mount the puck antenna on the outside of the PVC junction box.
5. Attach the PVC junction box to the wall.
6. Feed the terminal block through hole in the PVC junction box, and connect to Ring Access Controller Pro 2.
7. Peel off the liner on two 3M adhesive strips, and mount the Ring Access Controller Pro inside the PVC junction box by pressing and holding for 30 seconds.
Device inside call box:
- Clean the installation surface with cleaning solvent.
- Peel off the liner on two 3M adhesive strips.
- Alternatively, once all wires have been connected, place the device in the call box, so its position is secure without the requirement of fasteners to install the device.
Step 6: Setting up and activating Access Controller Pro 2
Once your Access Controller Pro 2 is installed, you will need to use the Ring app to set up the device, then call the provided activation number.
