Installation process:

1. Choosing a suitable installation spot

  • We recommend placing the sensor 15-30 cm from the edge of the desk.

  • Ensure the sensor is centred along the width of the workspace.

  • If you need to install the sensor at a different distance from the edge of the desk, please refer to the Range of Occupancy Sensor (DESK) detection article for further guidance.

  • In the case of metal supports under the desk that could potentially obstruct the PIR sensing cone, there are two approaches to installing the device:
    ​

    1. Install the device in front of the metal support. This is only possible if the final position of the device is no closer than 10 cm from the edge of the desk.

      ​

    2. Install the device behind the metal support, ensuring the distance from the support is proportional to its height. Please refer to Table 1 and the following images for guidance.

Table 1 - Distance vs Height

  • If the metal support is higher than 5 cm, always try to install the device in front of it.

Note: Install one or two sensors and test their functionality. Ensure that the sensors minimize false positives and false negatives. If the sensors are functioning correctly, proceed to the next steps of installation.

Warning:

  • Proximity to Desk Edge: Placing the device too close to the edge of the desk may cause false positives due to people walking near the desk. For more information, see the Range of Occupancy Sensor (DESK) detection article.

  • Distance from Desk Edge: Placing the device too far from the edge of the desk may lead to false negatives if the sitting person is not properly detected by the sensor. For more details, refer to the Range of Occupancy Sensor (DESK) detection article.

2. Cleaning the surface

  • Clean the surface with MEC3 alcohol cleaner. Ensure an area of approximately 10x10 cm around the intended sensor spot is cleaned.

  • Allow the surface to dry completely.

3. Placing devices on top of the desks

  • Simply place the MEC1 device upside down on the desk so that the QR code is easily accessible for scanning.

4. Adding devices into the system

  • Use the Spaceti Map Editor (SW1) to deploy the device into the system.

Note: For a detailed process on how to use the Map Editor, please refer to the manual Map Editor user guide.

5. Turning on the Devices

  1. EU Devices (SCP0L2PXXX)

    • Turn the sensor on by removing the battery contact blocking foil.

    • Ensure the foil does not get stuck at the edge of the hole, as this may cause it to tear.

    • If the foil does not release properly, replace the device with another one.

  2. US Devices (SCP0L1PXXX)

    • Use the SIM tool (TL4) to press the ON button on the device.

    • The ON button is located at the back of the sensor, in the hole closer to the label (see Img 5).

    • To confirm the device is turned on, check for a green LED blinking from the spot marked on Img 5.

Warning: Do not press the second button, as it is used to turn the device off.

6. Installation

  • Plug the platform MEC2 into the device MEC1 as shown in Images 6 and 7.

    • Position the platform so that the tab on the MEC1 component snaps into the recess of the MEC2 component.

    • On both the MEC2 platform and the bottom of the MEC1 device, you'll find the word "TOP" and an arrow. Ensure that the two arrows are facing each other; when they align, you will hear a click. Refer to the images for guidance.

  • The PIR lens on the MEC1 device must be oriented towards the edge of the desk.

Zip-ties

For installation on desk constructions such as metal supports or similar parts, use the "Z" version (zip ties) of the platform MEC2. Use pliers to tighten the zip ties and secure the device firmly. Use cutting pliers to trim any excess zip tie material.,

Stickers

For flat surfaces, use the specific version of the platform MEC2: "P" for plastic surfaces and "O" for other types of surfaces. First, remove the cover from the adhesive sticker. Next, stick the device to the underside of the table. Apply firm pressure for at least 5 seconds to ensure it adheres properly.

Screws

In special cases where the material is not suitable for using a sticker or when it's necessary to make the sensor difficult to remove, MEC4 screws can be used. When using screws:

  • Ensure the MEC2 (O or P) platform is properly oriented and positioned before installation.

  • Do not remove the adhesive cover.

  • Ensure that screws are inserted straight.

The platform must be installed without the sensor attached; the sensor is plugged in only after the platform is securely screwed into the desk.

Warning: Screws will cause irreversible damage to the desk!

Note: The sensor can be "unbuckled" from the platform at any time using the TL1 tool. Please refer to the Spaceti Sensor uninstallation manual for detailed instructions.

7. Validation

After all devices are installed, review the installation in the Spaceti dashboard.

  • “Green” Sensor - Unoccupied

  • “Red” Sensor - Occupied

  • “Gray” Sensor - Not sending data

All sensors should be in either the green or red state!

If the sensor is gray:

  1. Check if the sensor is turned on:

    • For the EU version of the device, ensure the protective foil has been removed.

    • For the US version of the device, try turning the sensor on again.

  2. Verify Data Transmission: Confirm if the sensor is sending messages (use the Papertrail logging system). If no messages are sent, there may be two potential issues:

    • Gateway Coverage Issue: Check if the Gateway coverage is sufficient. Try moving the Gateway closer or adding another Gateway to the floor. For detailed information about the Spaceti monitoring system, contact spaceti@support.com.

    • Device Issue: If the device itself is faulty, replace it with a new one. Ensure the new device is redeployed in the Spaceti system.
