MotionProtect Curtain User manual
Updated June 23, 2023
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 noti es the user about any events with push noti cations, 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

00:00

00:12

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 ashing on the device. Having caught an alarm state, the Hub triggers sirens and noti es 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.
What is correlation signal analysis and how does it work
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.
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 identi es movement before the system is armed, it will activate not immediately but the next it is polled by the hub.

The motion detector sensitivity level. The choice depends on the type of the object, the presence of probable sources of false alarms, and the speci cs of the protected area:
Low — there are likely sources of false alarms in the protected area. For example, tall bushes.

Normal (default value) — recommended value, suitable for most objects. Do not change it if the detector works correctly.
High — there is no interference in the protected area; the maximum range of detection and the alarm detection speed are important. For example, if the detector is installed in a narrow passage.
Before selecting the sensitivity level, conduct
the detection zone test. If during the test,
the detector doesn’t react to movement in 5 cases out of 5, the sensitivity should be increased.

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 lter and obstacles that may affect the detector’s eld of view and the radio signal transmission. Consider the detection range as well as the beam width when installing the detector. Incorrect device placement can lead to false alarms or improper operation of the device.
Horizontal and vertical detector’s angles of view

Detection range 3 meters 6 meters 9 meters 12 meters 15 meters

Beam width 0.3 meters 0.6 meters 0.9 meters 1.25 meters 1.55 meters

The device developed only for indoor use.
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 Low Normal High

Motion detection range w/ Signal Correlation Processing *
Up to 6 m Up to 7 m Up to 8 m

Motion detection range w/o Signal Correlation Processing * Up to 11 m Up to 13 m Up to 15 m

*at an ambient temperature of 23°C
If possible, avoid situations where the detector identi es 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.

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, oor 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 after moving the device still has a low or unstable signal strength, use a radio signal range extender.
The detector’s light lter 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 eld of view.
We recommend installing the detector at a height of 2.4 m
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 eld 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
to the included bracket.

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 ts tightly onto the attachment panel. If you try to detach the detector from the surface or the panel, you will receive a noti cation.
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 noti cation, and the LED will smoothly light up and go out when the detector detects any motion or if the tamper is activated.
