How to Install an Ajax Hub 2

The Ajax Hub 2 is the central controller for your Ajax security system. Every detector, siren, keypad, camera, and automation device communicates through the hub, making proper installation essential for reliable performance.

Whether you're installing a new system in your home or business, following the correct setup procedure will help ensure dependable communication, accurate alarm reporting, and a smooth installation experience.

This guide covers the basic installation process for the Ajax Hub 2.

Before You Begin

Before starting the installation, make sure you have:

  • Ajax Hub 2
  • Power supply
  • Ethernet cable
  • One or two activated Micro SIM cards (optional but recommended for backup communication)
  • Smartphone or tablet
  • Ajax Security System app
  • Internet router with an available Ethernet port
  • Mounting hardware
  • Phillips screwdriver

Step 1: Choose the Installation Location

Selecting the proper location is one of the most important steps.

The Hub 2 should be installed:

  • Indoors only
  • Near the center of the protected building whenever possible
  • In a secure location that is not easily accessible to intruders
  • Within reach of a wired Ethernet connection
  • Near a power outlet
  • Where cellular signal strength is adequate if SIM cards will be used

Avoid installing the hub:

  • Inside metal cabinets
  • Next to electrical service panels
  • Near large electric motors
  • In areas with excessive moisture
  • Inside utility rooms surrounded by concrete or metal
  • In direct sunlight or extreme temperatures

Proper placement improves communication with all Ajax devices.

Step 2: Install the SIM Card(s)

Although Ethernet is the primary communication path, installing cellular backup is highly recommended.

Before inserting the SIM card:

  • Verify the SIM card is activated.
  • Disable the PIN code if required by your carrier.
  • Confirm the SIM card has an active data plan.

Insert one or both Micro SIM cards into the slots located on the hub.

Using cellular backup allows the Hub 2 to continue communicating with the Ajax Cloud and monitoring station if the wired internet connection becomes unavailable.

Step 3: Connect Ethernet

The Ajax Hub 2 requires a hardwired Ethernet connection.

Connect the supplied Ethernet cable between the hub and your router or network switch.

Unlike some other security systems, the Hub 2 does not use Wi-Fi for internet connectivity.

After connecting Ethernet, verify that the network indicator confirms an active connection.

Step 4: Connect Power

Connect the supplied power adapter to the Hub 2.

Plug the adapter into a reliable electrical outlet.

Press and hold the power button for approximately two seconds until the LED indicator lights.

Allow several minutes for the hub to complete its startup process.

Step 5: Install the Ajax Security System App

Download the Ajax Security System app from the Apple App Store or Google Play Store.

Create an Ajax account if you do not already have one.

Verify your email address before continuing.

Step 6: Add the Hub to Your Account

Open the Ajax app.

Select Add Hub.

Scan the QR code located on:

  • The bottom of the Hub 2
  • The product packaging
  • The included documentation

Assign the hub a name and select the location where it will be installed.

Within a few moments, the hub should appear online in the app.

Step 7: Update the Firmware

Before adding any devices, check for available firmware updates.

Installing the latest firmware ensures:

  • Maximum system stability
  • Support for the newest Ajax devices
  • Latest security improvements
  • Access to new features

Allow any firmware updates to complete before continuing.

Step 8: Create Rooms

Organizing devices into rooms makes the system easier to manage.

Examples include:

  • Front Office
  • Warehouse
  • Garage
  • Living Room
  • Upstairs
  • Master Bedroom

As devices are added, assign each one to its appropriate room.

Step 9: Add Ajax Devices

Each Ajax device includes its own QR code.

Within the app, select Add Device and scan the QR code.

Typical devices include:

  • DoorProtect
  • MotionProtect
  • MotionCam
  • GlassProtect
  • FireProtect 2
  • StreetSiren
  • HomeSiren
  • KeyPad
  • SpaceControl
  • Relay
  • WallSwitch

Repeat the process until all devices have been added.

Step 10: Test Communication

Before permanently mounting detectors, perform communication tests.

The Ajax app allows you to verify:

  • Jeweller signal strength
  • Detection zone performance
  • Device communication quality

If signal strength is weak, relocate the detector before final installation.

Testing each device now helps prevent future communication issues.

Step 11: Configure Notifications

Customize how you want to receive alerts.

Notification options include:

  • Push notifications
  • Phone calls
  • SMS messages
  • Professional monitoring center notifications

Each user can configure their own notification preferences.

Step 12: Enable Professional Monitoring (Optional)

If your system will be monitored by a central station, contact your monitoring provider to complete registration.

Professional monitoring provides 24/7 response to alarm events and can dispatch emergency services when required. Alarm365 provides 24/7 professional monitoring services.

After activation, perform a complete alarm test to verify successful communication.

Step 13: Perform a Full System Test

Before placing the system into service:

  • Open every protected door and window.
  • Walk through each motion detector's coverage area.
  • Test smoke and heat detectors using their built-in test functions.
  • Verify sirens activate correctly.
  • Confirm notifications are received by all users.
  • Verify communication with the monitoring station if applicable.

Testing every device ensures your system is operating correctly before relying on it for protection.

Common Installation Mistakes

Many installation problems can be avoided by following a few best practices.

Avoid these common mistakes:

  • Installing the hub inside a metal enclosure
  • Failing to connect Ethernet before setup
  • Not installing cellular backup
  • Skipping firmware updates
  • Mounting detectors before testing signal strength
  • Installing detectors too close to large metal objects
  • Forgetting to test every device after installation
