Motion Detector II help [+M]

Mounting height and filtered area

Mounting height: At a mounting height of 2 metres, the Motion detector II [+M] always filters out the area up to 70 cm above the floor.

Adjusting the mounting height: Adjusting the mounting height also changes the filtered area accordingly.

Influence of the sensitivity settings

Front lens: The sensitivity settings have no influence on the small animal filter of the front lens.

Lower lens: The sensitivity settings only influence the small animal filter of the lower lens.

Recommendation for avoiding false alarms

Covering the lower lens: If there are pets or robot vacuum cleaners, it is recommended to cover the lower lens with the adhesive strip supplied in order to avoid false alarms.

With these measures, you can optimally set the small animal filter of your Motion detector II [+M] and reduce false alarms.

Your Motion detector II [+M] does not detect certain areas? Here are possible causes:

PIR sensor: The Motion detector II [+M] uses a PIR sensor (passive infrared sensor) that only detects movements in combination with a heat source. Movements behind a pane of glass are therefore not detected.

Mounting height: At a mounting height of 2 metres, approx. 70 cm from the floor are masked out (small animal filter). This masked area can be influenced by the mounting height.

Tips for improving detection

Adjust the mounting height: Check the mounting height of the motion detector. Adjusting the height can change the masked area and improve detection.

Positioning: Make sure that the motion detector is not blocked by glass or other obstacles that could impair heat detection.

Change the sensitivity: In the device settings of the Motion detector II [+M], you can adjust the sensitivity under “Sensitivity” depending on the application. In the alarm system, the motion detector is only certified according to EN 50131-2-2 with medium sensitivity.

With these measures, you can optimise the detection performance of your Motion detector II [+M].

Yes, the Motion detector II [+M] has protection class IP55 and can therefore also be used outdoors.

However, do not use the Motion detector II [+M] outdoors if you want to use it in the alarm system, as false alarms can occur more easily outdoors.

Proper mounting and placement ensures that your Smart Home Motion detector II [+M] functions optimally.

EN 50131-2-2 certification

The Motion detector II [+M] is EN 50131-2-2 certified under the following conditions:

Tamper contact: The tamper contact must be active (vibration sensor).

Sensitivity level: The sensitivity level must be set to medium sensitivity.

Mounting height: The Motion detector II [+M] must be mounted at a height of 2 metres.

These requirements ensure the security and reliability of the motion detector in accordance with the EN 50131-2-2 standard.

The brightness of the orientation light is measured in lux and depends on the distance:

1 metre distance: 1.5 lux

0.5 metre distance: 6.5 lux

0.25 metre distance: 21 lux

Colour temperature of the orientation light on the Motion detector II [+M]

The colour temperature varies between 2800 and 3200 kelvin (warm white).

Frontal movements: People moving directly towards the Motion detector II [+M] may be detected less reliably than people walking across the detection range.

Detection range

Up to 8 metres: The detector detects movements at an angle of 90°.

8 to 13 metres: The detection angle is reduced to 70°.

The motion detector provides reliable detection within these ranges and angles.

Temperature range

Operating temperature: The Motion detector II [+M] works between -20°C and +60°C.

Functional limitations

The PIR sensor (passive infrared sensor) is optimised to detect the thermal radiation of bodies. Its performance is influenced by the ambient temperature:

Colder temperatures: The PIR sensor becomes more sensitive at lower temperatures.

Higher temperatures: At temperatures above 30°C, the sensor becomes less sensitive. Limitations are to be expected from 30°C.

The Motion detector II [+M] can be operated within the specified temperature range, but its sensitivity may vary depending on the temperature.

Once the Motion detector II [+M] has detected a motion, it takes 1 minute by default until a new motion can be detected. If you use the “Motion light” service and have set a switch-on time of less than 5 minutes there, the motion detector detects a new motion after just 30 seconds.

To check the function of your Motion detector II [+M], please open your Smart Home App. In the device management, select the relevant Motion detector II [+M] and, under “Function tests”, select the application relevant to you: “Function test for alarm system” or “Function test for motion light”.

Please note that the mounting height can have a major influence on the detection range.

The anti-theft protection is a security function of the Motion detector II [+M] that sends a signal to the controller, and thus also to the connected smartphones, when the device is forcibly removed from the wall/corner: “Warning: The motion detector has been removed from its installation location.”

The anti-theft protection of your device is triggered by a vibration sensor, not by a mechanical contact. Please note that in rare cases this can also be caused by strong vibrations in the surroundings, for example when a nearby door is slammed shut.

Small animal filter: Your Bosch Smart Home Motion detector II [+M] always filters out the area up to 70 cm above the floor (at a mounting height of 2 m). The filter can be influenced by the mounting height (does not apply to the lower lens).

Creep zone protection: The creep zone protection is an additional lens on the underside of the Motion detector II [+M]. This ensures that movements below the detector are also detected. If you have pets or a robot vacuum cleaner, for example, you can cover this lens with one of the adhesive pads supplied, as the small animal filter does not apply to this lens.

Certification
