Step 3

Mount the hardware

Fix the reader and exit button to the wall.

Holes to drill: 4 mounting + 1 cable
  1. Drill four holes on the wall or door for the self-tapping screws, plus one hole for the cable.
  2. Put the rubber bungs into the four holes.
  3. Fix the bracket firmly on the wall with four self-tapping screws.
  4. Fix the bracket and reader together with the fixing-bracket screw.
  5. Thread the cable through the cable hole.
  1. Drill two holes on the wall or door for the self-tapping screws, plus one hole for the cable.
  2. Put the rubber bungs into the two holes.
  3. Fix the bracket firmly on the wall with two self-tapping screws.
  4. Fix the bracket and exit button together with the fixing-bracket screw.

6 screws on the back
  1. Unscrew the six screws on the back of the device.
  2. Insert the SIM card into the holder.

Wi-Fi revision?
Your reader has no SIM slot — skip this step and get it online in Step 6.
SIM installation — unscrew, insert, close, tighten.
Step 5

Wire — reader relay

Direct wiring using the reader's built-in relay.

The reader's own relay switches the lock. The exit button can be wired in parallel on the power line if needed.

1 · Connect power and data wires
Reader · Red PSU · +12V
Reader · Black PSU · GND (−)
Reader · Yellow Exit button · Signal
Reader · White Exit button · GND

Red and black power the reader; the yellow and white data wires run to the exit button, which can be connected in parallel if needed.

2 · Lock output
Fail-safe — unlocks on power loss

Keeps the maglock energized and locked. When access is granted the relay opens the NC circuit, cutting power and unlocking the door.

PSU · + Reader · COM (Brown)
Reader · NC (Orange) Maglock · +
PSU · − Maglock · −

Keeps the strike unpowered and locked. When access is granted the relay closes the NO contact, delivering power to unlock the strike.

Step 6

Connect to the network

Get the reader online over LTE, Wi-Fi, or Matter over Thread.

The reader comes in two hardware revisions — LTE and Wi-Fi — so pick the tab that matches yours. Matter over Thread works on both.

Hardware: LTE revision

Insert the SIM and you're online

Nothing to configure — just check it's Online
  1. Insert the SIM card as shown in Step 4.
  2. Power the reader on. It joins the mobile network by itself.
  3. Open the Admin Panel → Devices and check that the reader's card shows Online.
No SIM slot?
Then you have the Wi-Fi revision — hop over to the Wi-Fi tab.
The SIM holder sits under the back cover — Step 4 walks you through it.

Pair over Bluetooth, then share your Wi-Fi

Stay next to the reader
  1. In the Admin Panel, open Devices, find your reader and choose ⋮ → Configure Wi-Fi.
  2. Click Pair Lock and pick your reader from the Bluetooth list — it shows up as SK#….
  3. Type your network name (SSID) and password, then click Connect Lock to Wi-Fi.
  4. Wait for “Wi-Fi configured”. That's it — the reader is online.
Your password stays private
It goes straight to the reader over Bluetooth — the Admin Panel never stores it.
