Adding to the system
Prerequisites
The device is configured using the PRO Safe app. Please ensure that you have installed the PRO Safe app, created an account and added the hub to the app. For details on adding the hub, please refer to the user manual for the relevant hub.
📖 NOTE:
- Make sure the hub has a stable internet connection.
- Make sure that the app version is 1.91 or higher and the hub version is v1.001.0000000.0.R.210303 or higher.
- Make sure the hub is disarmed (system disarmed).
- Make sure the detector is switched off (power switch in the OFF position).
Further information
This user guide uses operations in iOS as examples.
Procedure:
Step 1. In the app, go to the hub screen and tap the tab Device or Area.
Step 2. Tap the ‘(+)’ button in the top right-hand corner and select the option Add a peripheral device.
Next, enter the detector’s serial number using one of the options listed below:
- By using your mobile phone’s camera to scan the detector’s QR code (requires granting the app permission).
- Tap the [🌄] button in the top right-hand corner and select a photo of the detector’s QR code from your mobile phone’s gallery (this requires granting the app permission).
- By tapping the Enter SN manually button and adding the serial number manually.
Once you have found the detector, click the button Next.
Step 3. Follow the instructions in the app and switch on the detector when prompted. Then tap Next.
Step 4. Wait for the pairing to complete.
Step 5. Customise the detector name, select the area and tap Finish.
Installation
The detector supports wall or corner mounting.
Choosing the location:
When choosing a suitable location, the following factors must be taken into account to eliminate false alarms and ensure reliable detector operation:
- The area of the intruder's expected movement.
- The presence of sources of warm or cold air flow, direct sunlight or moving objects in the detector's field of view: air conditioning, stoves, fireplaces, fans, heated towel rails, curtains.
- The radio signal strength of the connection to the hub.
- The distance between the detector and the hub or range extender.
- The presence of obstacles limiting radio signal transmission: walls, ceilings, mirrors, metal or other large objects in the room.
- Distance between the detector and other system devices with MW detection (min. 20 cm or more).
Do not place the detector:
- Outdoors – there is a high risk of false alarms or damage to the detector.
- In an area where objects and structures block its field of view (e.g. curtains, glazed surfaces, indoor plants) – motion detection will be limited.
- In areas with temperature and humidity outside the limits stated in the technical specifications – the detector may be damaged.
- Within 1 m of the hub or range extender and in places with unstable or low radio signal quality – the risk of communication loss problems increases.
Before installing the detector at the desired location, first check the signal strength of the connection to the hub using the mobile app. We recommend installing the detector in a place with a signal strength of at least 50% (min. 2 indicator bars).
Detection zone:
The expected direction of the intruder's movement must be perpendicular to the axis of the detector lens. Make sure that furniture, indoor plants, vases and decorative or glass elements do not obstruct the detector's view.
When properly installed and configured, the detector does not react to pets up to 50 centimetres in height and up to 18 kilograms in weight. In particular, it is necessary to observe the recommended installation height and to set the corresponding detection sensitivity according to the size of the animal (the larger the animal, the lower the sensitivity).

Wall mounting:
Procedure:
Step 1. Remove the mounting panel and use a thin drill bit to drill the holes intended for wall mounting.
Step 2. Mark the positions of the mounting panel holes on the selected surface; use suitable fixing material (e.g. wall plugs and screws) to fasten the mounting panel.

Step 3. Fit the detector onto the mounting panel in the direction indicated by the arrow.

Corner mounting:
Procedure:
Step 1. Remove the mounting panel and use a thin drill bit to drill the holes intended for corner mounting.
Step 2. Mark the positions of the mounting panel holes on the selected surface; use suitable fixing material (e.g. wall plugs and screws) to fasten the mounting panel.

Step 3. Fit the detector onto the mounting panel in the direction indicated by the arrow.

Battery replacement
The battery is pre-installed at the factory and the detector is ready for immediate use. If the battery is flat, it must be replaced.
Procedure:
Step 1. Remove the detector from the mounting panel and switch it off.

Step 2. Using a suitable screwdriver, loosen the three screws at the rear of the housing and then separate the two parts of the housing by moving them in the direction of the arrow.

Step 3. Replace the battery and make sure the polarity is observed.
Step 4. Join the two parts of the housing in the reverse manner, secure them with the screws, switch on the detector and return it to the mounting panel.
⚠ DANGER:
Keep new and used batteries out of the reach of children. Do not ingest the battery; there is a risk of chemical burns.
⚠ NOTICE:
The pre-installed battery provides up to 4 years of detector operation under normal use and normal operating conditions. More frequent use may shorten the battery life. You can check the current capacity status of the power battery at any time in the ProSAFE app.
