MotionProtect Curtain User Manual

Updated

MotionProtect Curtain is a curtain type wireless motion detector. The detector has a narrow horizontal detection angle and is designed for indoor perimeter control: windows, doorways, and other entrances or exits of the guarded facility. Maximum motion detection distance is 15 m.

MotionProtect Curtain integrates into Ajax security systems, connecting to a hub through the Jeweller secure protocol. Wireless coverage may reach up 1,700 m line-of-sight. The pre-installed battery ensures up to 3 years of autonomous operation.

An iOS or Android app is used for detector setup. It also notifies the user about any events with push notifications, SMS, or calls (if enabled).

Ajax can be connected to the central monitoring station of a security company.

Connection to ocBridge Plus and uartBridge integration modules is not provided.

Operating Principle

MotionProtect Curtain’s IR sensors detect intrusion into the premises by detecting moving objects having a temperature close to that of the human body.

Once the system is armed, the detector starts polling its two IR sensors. If a motion is detected, an alarm state is instantly sent to the hub and green LED starts flashing on the device. Having caught an alarm state, the Hub triggers sirens and notifies the user and the security company.

Motion alarms are sent every 5 seconds

To prevent false alarms, MotionProtect Curtain has a Correlation Signal Processing functionality that can be enabled in the detector’s settings. Once it is active, the detector starts sending alarm states to the hub only if an identical motion signal is registered by both IR sensors. If it is disabled, MotionProtect Curtain sends an alarm state even with one of the two IR sensors triggered.

Pairing the Detector with a hub

Before you start pairing the detector:

  1. Turn on your hub and check the Internet connection (via Ethernet and/or GSM).
  2. Install the Ajax application on your smartphone. Create an account, add your hub to the app, and create at least one room.
  3. Check the status of the hub in the app to make sure it is disarmed and is not updating.

Please note that only a user with admin permissions can add devices to the hub

Pairing MotionProtect Curtain with a hub:

  1. In the Ajax mobile app, tap Add device.
  2. Name the device, scan the QR code or enter it manually (placed on the back of the detector body or its packaging), select the room for placement, and tap Add. The countdown will start.

  3. Turn on the detector by holding its power button for 3 seconds.
    ajax motionprotect curtain

For detection and pairing to occur, the device must be within a hub’s wireless coverage (at the same facility). The connection request will be sent to the Hub only once the device turns on.

If the MotionProtect Curtain fails to connect to the hub, it will automatically power down within 6 seconds after turning on. There is no need to turn off the device to retry.

If the MotionProtect Curtain has already been paired with another hub, turn off the detector, and then follow the standard pairing procedure.

After pairing, the detector will appear on the app’s hub device list. The frequency of the device status updates depends on the polling interval indicated in the hub’s settings (36 seconds by default).

If the detector identifies movement before the system is armed, it will activate not immediately but the next it is polled by the hub.

Integrity Testing

Ajax security systems can run tests to verify the integrity of connected devices.

The tests start instantly, but no later than within 36 seconds by default. The test start time depends on the detector polling interval setting (see the Jeweller section in the Hub settings).

Detector Placement

The effectiveness of the security system depends on detector placement. Choosing a location to install MotionProtect Curtain, consider the direction of the light filter and obstacles that may affect the detector’s field of view and the radio signal transmission.

The device developed only for indoor use.

Incorrect placement may result in false alarms or faulty operation of the detector.

Do not install the detector:

  • Outside the premises (outdoors)
  • In front of the windows within reach of direct sunlight
  • Opposite of the objects that rapidly change temperature (e.g., electric and gas heaters)
  • Opposite of the moving objects having a temperature close to that of the human body (curtains swaying above a heating radiator)
  • In places with fast air circulation (near fans, open windows or doors)
  • Near metal objects and mirrors that cause the attenuation or interfere with radio signals
  • Within any premises with the temperature and humidity beyond the permitted range
  • Closer than 1 m to a hub

If the detector keeps reacting to interference and raising false alarms, but it is impossible to install it anywhere else, the Correlation Signal Processing can be enabled in the settings.

Please note that if the Correlation Signal Processing is enabled, the range of motion detection is reduced depending on the detector sensitivity chosen

Sensitivity Motion detection range w/ Signal Correlation Processing * Motion detection range w/o Signal Correlation Processing *
Low Up to 6 m Up to 11 m
Normal Up to 7 m Up to 13 m
High Up to 8 m Up to 15 m

*at an ambient temperature of 23°C

If possible, avoid situations where the detector identifies movement at a longer distance than required. The best place to install it is within an enclosed place. For instance, to detect movement in an archway, install the detector in it. This way, the detector will be triggered only by a person that enters it.

To prevent the detector from reacting to domestic animals, install it upside down, leaving space for the free movement of animals below the detection zone.

ajax motionprotect curtain

The placement of a MotionProtect Curtain also depends on the distance to a hub and whether there are any obstacles between the devices that may hinder the radio signal, e.g., walls, floor deck, or large objects in the room.

Check the signal strength at the placement location. If you have a signal level of one bar, there is no guarantee of the security system’s stable operation. Take all necessary precautions to ensure maximum signal level. At least try moving the device—even 20 cm can make a difference.

If the device still shows low or unstable signal level even after you move it, use a ReX radio signal range extender.

The detector’s light filter should be directed perpendicularly to the expected entry path to the room!

Make sure that no furniture, home plants, vases, decorative or glass structures are blocking the detector’s field of view.

We recommend installing the detector at a height of 2.4 m!

ajax motionprotect curtain

Installing the detector at any other height will narrow the detection zone, affecting the quality of motion detection.

Keep in mind that MotionProtect Curtain does not detect movement behind the glass. Therefore, do not install the detector in places where glass structures may block its range of view, e.g., in places where an open window may obstruct the device’s field of view.

Detector Installation

Before installing the detector, make sure that you have chosen an appropriate location as indicated in this manual.

There are two options for installing MotionProtect Curtain: 

  • directly to a surface
ajax motionprotect curtain
  • to the included bracket.
ajax motionprotect curtain

Installation procedure:

  1. Attach the SmartBracket panel or a bracket to the surface with the included screws or other equally reliable fasteners. Screw the SmartBracket panel onto the included bracket.
  2. Attach the detector to the SmartBracket attachment panel.
  3. Mount the detector on the SmartBracket attachment panel using a screw.

The double-sided adhesive tape should be used only for the temporary installation of the detector. It will dry out eventually, becoming unable to reliably hold the detector and possibly causing false alarms in the security system. The fall of the device may also result in its damage.

If the detector’s LED fails to light up after the device is attached to the SmartBracket, check the tamper status in the Ajax app and then check if it fits tightly onto the attachment panel. If you try to detach the detector from the surface or the panel, you will receive a notification.

Having installed the detector, run the Detection Zone Test. In case of incorrect operation, the detector needs to be relocated.

Detector Care and Battery Replacement

Check the integrity of the MotionProtect Curtain detector regularly. Clean the detector body from dust, spider webs, and other contaminations as they appear. Use soft dry cloth suitable for equipment care.

Do not clean the detector with any substances containing alcohol, acetone, gasoline, or any other active solvent. Wipe the lens carefully and gently—any scratches on the plastic may reduce the detector’s sensitivity.

The pre-installed battery ensures up to 3 years of autonomous operation (at a polling interval of 3 min). If the detector battery is nearly depleted, the security system will send a notification, and the LED will smoothly light up and go out when the detector detects any motion or if the tamper is activated.
