Adding MotionProtect Sensors

How to Add an Ajax MotionProtect Sensor

The Ajax MotionProtect is a wireless indoor motion detector designed to detect human movement while helping to reduce false alarms. Using Ajax's Jeweller wireless communication technology, MotionProtect delivers fast and reliable alarm transmission while providing years of battery life.

This guide explains how to add a MotionProtect detector to your Ajax Hub and install it for the best possible performance.

Before You Begin

Before adding a MotionProtect detector, make sure you have:

  • An installed and operational Ajax Hub
  • The Ajax Security System app
  • Administrator access to the hub
  • A MotionProtect detector
  • A smartphone or tablet
  • The detector within communication range of the hub

If your hub is monitored by a central station, place the system in maintenance or test mode before adding new devices.

Step 1: Open the Ajax App

Open the Ajax Security System app and select the hub where you want to install the detector.

Tap Devices.

Select Add Device.

Step 2: Enter Device Information

Enter the following information:

  • Device name (Example: Front Entry Motion)
  • Select the room where the detector will be installed
  • Scan the QR code located on the back of the detector or on the packaging

Each MotionProtect has a unique QR code that identifies the device.

Step 3: Turn On the Detector

Remove the detector from the packaging.

Press and hold the power button until the LED briefly lights.

The detector will automatically attempt to connect to the hub.

Within a few seconds, the MotionProtect should appear in the device list.

Step 4: Choose the Best Mounting Location

Proper placement is critical for reliable motion detection.

Recommended mounting height:

  • Approximately 7.9 to 8.2 feet (2.4 meters) above the floor

Install MotionProtect:

  • In a room corner whenever possible
  • Facing likely walking paths
  • Where an intruder will walk across the detection area rather than directly toward it
  • On a stable wall

Avoid installing the detector:

  • Facing windows with direct sunlight
  • Above heating vents or radiators
  • Near fireplaces
  • In areas with rapid temperature changes
  • Behind furniture or curtains
  • Where pets can easily climb directly in front of the detector

Correct placement improves detection performance while reducing false alarms.

Step 5: Perform the Jeweller Signal Strength Test

Before permanently mounting the detector, verify communication with the hub.

In the Ajax app, select the MotionProtect detector and run the Jeweller Signal Strength Test.

For best performance, the detector should display a strong communication signal.

If signal strength is weak, try moving the detector or consider installing an Ajax ReX range extender if needed.

Step 6: Run the Detection Zone Test

Use the Detection Zone Test to confirm proper coverage.

Walk through the protected area several times.

Verify that the detector responds consistently throughout the intended coverage area.

If necessary, adjust the detector location or angle before mounting it permanently.

Step 7: Mount the Detector

Once testing is complete:

  • Attach the SmartBracket mounting plate securely to the wall using the supplied screws.
  • Avoid using adhesive tape as a permanent mounting solution.
  • Slide the MotionProtect onto the SmartBracket until it locks into place.

Proper mounting helps ensure tamper protection operates correctly.

Step 8: Configure Detector Settings

The Ajax app allows you to customize several MotionProtect settings, including:

  • Motion sensitivity
  • Entry and exit delays
  • Night Mode operation
  • Always Active mode
  • Alarm processing
  • LED indication
  • Signal strength monitoring

Adjust these settings based on the room and your security requirements.

Step 9: Test the Installed Detector

After installation:

  • Arm the system.
  • Wait for the detector to enter armed mode.
  • Walk through the protected area.
  • Confirm that motion is detected.
  • Verify that notifications are received.
  • If professionally monitored, verify communication with the monitoring center.

Testing confirms the detector is operating correctly before relying on it for protection.

Common Installation Mistakes

Avoid these common errors:

  • Mounting lower or higher than the recommended height
  • Installing where direct sunlight shines on the detector
  • Facing HVAC vents or heating equipment
  • Mounting behind furniture or shelving
  • Skipping the signal strength test
  • Skipping the detection zone test
  • Installing before assigning the detector to the correct room

Frequently Asked Questions

How high should MotionProtect be installed?

The recommended installation height is approximately 7.9 to 8.2 feet (2.4 meters).

Can MotionProtect detect pets?

MotionProtect includes pet immunity designed to reduce false alarms from small pets when installed according to Ajax recommendations. Proper mounting height and placement are essential for effective pet immunity.

How long does the battery last?

Under normal operating conditions, the pre-installed battery can last up to 5 years, depending on usage and environmental conditions.

Does MotionProtect require Wi-Fi?

No. MotionProtect communicates directly with the Ajax Hub using the Jeweller wireless protocol and does not connect to Wi-Fi.

Can I install MotionProtect myself?

Yes. MotionProtect is designed for DIY installation and can usually be added to an Ajax Hub in just a few minutes.

Final Thoughts

The Ajax MotionProtect is one of the most important components of any Ajax security system. Correct placement, proper testing, and thoughtful configuration help ensure fast and reliable intrusion detection while minimizing false alarms.

Taking a few extra minutes to verify signal strength and detection coverage before permanent installation will help your system deliver the level of protection it was designed to provide.
