Compatible hubs and range extenders
An Ajax hub with the firmware OS Malevich 2.16 and higher is required for the detector to operate.
Operating principle
DoorProtect S Plus is a wireless opening, shock, and tilt detector. If a standard installation method is used, the device consists of two parts. The first part is the detector with two reed switches, the shock and tilt sensor. The second part is the magnet that is needed to detect opening. All sensors of the detector work independently. Each sensor of the detector can be enabled or disabled in Ajax apps.
Opening is detected by a reed switch built into the detector and a magnet. When the magnet approaches or moves away, the reed switch changes the state of the contacts and notifies of opening/closing. The detector is equipped with one small and one big magnet.
The magnet can be attached to both sides of the detector. DoorProtect S Plus works with one magnet on one side only. If magnets are attached on both sides, the detector cannot detect the opening correctly.
A small magnet works at a distance of 1 cm, and the big one — up to 2 cm. If you do not need to detect the opening of a door or window, you can install the detector without a magnet.
The shock sensor detects attempts to knock out a window or door and reacts to vibration when attempts are made to knock out a lock or break a door.
The tilt sensor detects vertical axis deviation of a device. Before the system is armed, the sensor remembers the initial position and is triggered if the deviation is more than 5° (depending on the settings). This helps to protect windows, including skylights, and arm the system when the window is in the ventilation mode (be sure to deactivate the main detector in the settings before you do this).
If triggered, the armed detector instantly sends an alarm to the hub, which activates the sirens connected to the system, triggers scenarios, and notifies users and the security company. All detector alarms and events are recorded in the events feed of the Ajax apps.
Jeweller data transfer protocol
Jeweller is a two-way wireless data transfer protocol that provides fast and reliable communication between hub and devices. The detector uses Jeweller to transmit alarms and events.
Sending events to the monitoring station
An Ajax system can transmit alarms to the PRO Desktop monitoring app as well as the central monitoring station (CMS) in the formats of SurGard (Contact ID), SIA (DC-09), ADEMCO 685, and other protocols.
DoorProtect S Plus can transmit the following events:
- Tamper alarm. Tamper recovery.
- Detector alarm/recovery.
- Alarm/recovery of a third-party wired detector connected to DoorProtect S Plus.
- Loss of connection with the hub (or radio signal range extender). Restoration of connection.
- Permanent deactivation/activation of the detector.
- One-time deactivation/activation of the detector.
When an alarm is received, the operator of the security company monitoring station knows what happened and precisely where to send a rapid response team. The addressability of Ajax devices allows sending events to PRO Desktop or the CMS the type of the device, its name, security group, and virtual room. Note that the list of transmitted parameters may differ depending on the kind of CMS and the protocol selected for communication with the monitoring station.
The ID and the number of the device can be found in its states in the Ajax app.
Adding to the system
DoorProtect S Plus is incompatible with Hub and third-party security control panels.
To connect DoorProtect S Plus to the hub, the detector must be located at the same secured facility as the system (within the range of the hub radio network). For the detector to work via the ReX or the ReX 2 radio signal range extender, you must first add the detector to the hub, then connect it to ReX or ReX 2 in the settings of the range extender.
The hub and the device operating at different radio frequencies are incompatible. The radio-frequency range of the device may vary by region. We recommend purchasing and using Ajax devices in the same region. You can check the range of operating radio frequencies with the technical support service.
Before adding a device
- Install an Ajax PRO app.
- Log in to a PRO account or create a new one.
- Select a space or create a new one.
The space functionality is available for apps of such versions or later:
- Ajax Security System 3.0 for iOS;
- Ajax Security System 3.0 for Android;
- Ajax PRO: Tool for Engineers 2.0 for iOS;
- Ajax PRO: Tool for Engineers 2.0 for Android;
- Ajax PRO Desktop 4.0 for macOS;
- Ajax PRO Desktop 4.0 for Windows.
- Add at least one virtual room.
- Add a compatible hub to the space. Ensure the hub is switched on and has internet access via Ethernet, Wi-Fi, and/or mobile network.
- Ensure the space is disarmed, and the hub is not starting an update by checking statuses in the Ajax app.
This product line is developed for projects. Only accredited Ajax Systems partners can install, and administer Superior products.
Connecting to the hub
- Open the Ajax PRO app. Select the hub where you want to add the device.
- Go to the Devices tab and click Add device.
- Name the device, scan, or type in the QR code (placed on the detector and the package box), and select a room and a group (if Group Mode is enabled).
- Press Add.
- Switch on the device.
If the connection fails, turn the detector off and try again in 5 seconds. Note that if the maximum number of devices has already been added to the hub (depending on the hub model), you will be notified when you try to add a new one.
The detector connected to the hub will appear in the list of hub devices in the Ajax app. Updating the statuses of devices in the list depends on the Jeweller or Jeweller/Fibra settings; the default value is 36 seconds.
DoorProtect S Plus works with one hub. When connected to a new hub, the detector stops sending events to the old one. When added to a new hub, the detector is not removed from the device list of the old hub. This must be done manually in the Ajax app.

| LED indication | Event | Note |
| Lights up green for about one second | Turning on the detector | |
| Lights up for a few seconds | Pairing the detector with the hub | |
| Lights up green for 1 second | Alarm in case of opening, shock, tilt, or tamper triggering | An alarm is sent once in 5 seconds |
| During the alarm, it slowly lights up green and slowly goes out | Detector batteries need to be replaced | Replacement of the detector battery is described in this article |
Functionality testing
The Ajax system offers several tests to help select the device installation place. Tests do not start immediately. However, the waiting time does not exceed the duration of one “hub—device” polling interval. The polling interval can be checked and configured at hub settings (Hub → Settings 
→ Jeweller or Jeweller/Fibra).
To run a test, in the Ajax app:
- Select the required hub.
- Go to the Devices tab.
- Select DoorProtect S Plus from the list.
- Go to Settings .
- Select a test:
- Run the test.
Detector placement
The device is designed for indoor use only.
When choosing where to place DoorProtect S Plus, consider the parameters that affect its operation:
- Detection zone.
- Jeweller signal strength.
- Distance between the detector and the hub or range extender.
- Presence of obstacles for radio signal passage: walls, interfloor ceilings, large objects located in the room.
Consider the recommendations for placement when developing a project for the security system of the facility. The security system must be designed and installed by specialists. A list of recommended partners is available here.
Place the detector on a movable part inside or outside the door frame/window frame for shock and tilt detection. For opening detection, attach the magnet to the moving part of the door (window).
When mounting the detector on perpendicular planes, use a small magnet. The distance between the small magnet and the detector should not exceed 1 cm.
Use a big magnet if parts of DoorProtect S Plus are mounted on the same plane. The distance between the big magnet and the detector should not exceed 2 cm.
The magnet can be attached to the right or to the left side of the detector. DoorProtect S Plus works with one magnet on one side only. If magnets are attached on both sides, the detector cannot detect the opening correctly.
If there is no need to detect opening, the magnet is not installed. In this case, it is necessary to disable the opening sensor in the detector settings in the Ajax apps.
If necessary, the detector can be positioned horizontally.
Do not install the detector with the LED indicator facing down, as this may cause it to fall and fail due to damage.
The DoorProtect S Plus working distances*
Relatively to the detector, the magnet can move along three axes: X (X1), Y, or Z. It depends on the DoorProtect S installation location. For example:
- X-axis (or X1): on the roller shutter.
- Y-axis: on the sliding door.
- Z-axis: on the window.
| Axis | Big magnet on the non-ferromagnetic surfaces (e.g., wooden doors) | Big magnet on the ferromagnetic surfaces (e.g., metal doors) | ||
| Removal distance, mm | Approach distance, mm | Removal distance, mm | Approach distance, mm | |
| X | 19 | 11 | 19 | 11 |
| X1 | 23 | 15 | 22 | 14 |
| Y | 26 | 17 | 18 | 10 |
| Z | 33 | 20 | 24 | 10 |
* — For small magnet all measurements will be reduced.
Signal strength
The Jeweller signal strength is determined by the number of undelivered or corrupted data packages over a certain period of time. The icon on the Devices 
tab indicates the signal strength:
- Three bars — excellent signal strength.
- Two bars — good signal strength.
- One bar — low signal strength, stable operation is not guaranteed.
- Crossed out icon — signal is missing.
Check the Jeweller signal strength before final installation. With a signal strength of one or zero bars, we do not guarantee stable operation of the device. Consider to relocate the device as repositioning even by 20 cm can significantly improve the signal strength. If there is still a poor or unstable signal after the relocation, use a radio signal range extender.
Detection zone
Consider the operating area of the magnet when choosing the installation location. Smaller magnets act at distances up to 1 cm from the reed switch, while larger ones act at distances up to 2 cm.
When installing the detector, perform the Detection Zone Test. This allows you to check the operation of the device and accurately determine the sector in which the detector reacts to movement.
Do not install the detector
- Outdoors. This can lead to false alarms and detector failure.
- Inside metal structures. This may result in the loss of the radio signal.
- Near mirrors. This may result in the shielding or attenuation of the radio signal.
- Inside premises with temperature and humidity outside the permissible limits. This could damage the detector.
- Closer than 1 meter from the hub or radio signal range extender. This can lead to a loss of communication with the detector.
- In a place with a low signal level. This may result in the loss of the connection with the hub.
Installation
Before installing DoorProtect S Plus, ensure that you have selected the optimal location that complies with the requirements of this manual.
To mount a detector:
- Remove the SmartBracket mounting panel from the detector by sliding it down. Unscrew the holding screw first.
- Fix the SmartBracket panel using double-sided tape to the selected installation spot.
Double-sided tape can only be used for temporary installation. The device secured with the tape may come unstuck from the surface at any time. As long as the device is taped, the tamper will not trigger when the device is detached from the surface.
- Place the detector on SmartBracket. The device LED indicator will flash. It is a signal indicating that the tamper on the detector is closed.
If the LED indicator doesn’t light up during placing the detector on SmartBracket, check the tamper status in the Ajax app, the integrity of the fastening, and the tightness of the detector fixation on the panel.
- Fix the magnet on the surface with double-sided tape.
If there is no need to detect opening, the magnet is not installed.
- Run the Jeweller signal strength test. The recommended signal strength is two or three bars. If the signal strength is low (a single bar), we do not guarantee stable operation of the device. Consider relocating the device as repositioning even by 20 cm can significantly improve the signal strength. If there is still poor or unstable signal after the relocation, use a radio signal range extender.
- Run the Detection Zone Test:
- Run a test to check the opening sensor: open and close the window or door where the device is installed several times. Monitor the reaction of the LED: it should flash every time the door/window is opened or closed. If the detector doesn’t respond in 5 out of 5 cases during the test, try to change the installation spot or method. The magnet may be too far from the detector.
- To check the tilt and shock sensor, enable these sensors in the detector settings before starting the test. Remove the detector from the mounting panel and place it on a flat surface. Run the test. To test the tilt sensor, lift the detector off the surface and tilt it vertically. To test the shock sensor, simulate a shock on the surface on which the detector is placed. Monitor the reaction of the LED: it should flash with each registered tilt and shock.
- Run Signal Attenuation Test. During the test, the signal strength is artificially reduced and increased to simulate different conditions at the installation location. If the installation spot is chosen correctly, the detector will have a stable signal strength of 2–3 bars.
- If the tests are passed successfully, secure the detector and magnet with bundled screws. Use all fixing points.
- To mount the detector: remove it from the SmartBracket mounting panel. Then fix the SmartBracket panel with bundled screws. Install the detector on the panel.
- To mount a big magnet: remove it from the SmartBracket mounting panel.
Then fix the SmartBracket panel with bundled screws. Install the magnet on the panel.
- To mount a small magnet: disassemble its enclosure by prying up the back with a flat object. Use a slotted screwdriver for this. Fix the part with magnets on the surface; use the bundled screws for this. Then install the front panel in its place.
- To mount the detector: remove it from the SmartBracket mounting panel. Then fix the SmartBracket panel with bundled screws. Install the detector on the panel.
- Tighten the holding screw on the bottom of the detector’s and magnet’s enclosure. The screw is needed for more reliable fastening and protection of the detector and the magnet from quick dismantling.
If using screwdrivers, set the speed to the minimum so as not to damage the SmartBracket mounting panel during installation. When using other fasteners, ensure they do not damage or deform the panel. To make mounting the detector or magnet easier, you can pre-drill the screw holes while the mount is still secured with double-sided tape.
Connecting a third-party wired detector
A wired detector with an NC (normally closed) contact type can be connected to DoorProtect S Plus. It can be a motion, opening, or vibration detector.
DoorProtect S Plus will not power the third-party detector. The detector should be connected separately. To learn the type and input voltage of the third-party detector, refer to the device documentation or contact the manufacturer’s technical support.
Install the third-party detector no more than 1 meter away from DoorProtect S Plus. Increasing the length of the wire degrades the quality of communication between devices.
To connect the third-party wired detector:
- Remove the detector from the mounting panel if already installed.
- Carefully break out the plugs in the detector enclosure for the output of wires.
- Route the cable of the third-party wired detector into the DoorProtect S Plus enclosure.
- Connect the wired detector to DoorProtect S Plus terminals.
- In DoorProtect S Plus settings, enable the External Contact option.
- Check operation of the connected wired detector. If the external detector is actuated, you will receive a notification.
To receive an alarm when the roller shutters open, connect a wired roller shutter motion detector with a normally closed contact to DoorProtect S Plus.
Maintenance
Check the functioning of the detector regularly. The optimal frequency of checks is once every three months. Clean the device enclosure of dust, cobwebs, and other contaminants as they emerge. Use a soft dry wipes suitable for equipment care.
Do not use substances that contain alcohol, acetone, petrol, and other active solvents to clean the detector.
DoorProtect S Plus runs for up to 5 years with bundled batteries at 10 openings/closings per day with the standard Jeweller or Jeweller/Fibra settings. The security system will send an early warning about replacing the batteries. In case of an alarm, the LED will slowly light up green and go out.
We recommend you replace the batteries immediately upon notification. It is advisable to use lithium batteries. They have a large capacity and are less affected by temperatures.
