If External Antenna is select, both antennas must be plugged in before any operation occurs.
This product must not be disposed of in the normal waste stream. It contains a battery pack and electronic components and so should be recycled appropriately.

Theory of Operation

The Accelerometer is a low touch Internet of Things (IoT) device. It is designed to as simple as possible to install and activate, set and forget. Data is retrieved from the device via our cloud-based platform or via API to yours using the integrated LTE/CAT-M1 cellular communications. The device also uses GPS for time synchronisation where comparison of events between nodes is required.
The device sensor is always monitoring for events, and can be continuously monitoring, or set to a triggered state. Remote configuration is possible to change the acquisition and upload frequency.

Parts List

The Viotel Accelerometer has an optional addition including external antennas*, external power** and mounting kits, please contact sales@viotel.co before ordering.

Two-Sided Adhesive
Clean and dry the mounting locations surface. Peel off the red plastic layer on the back of the node and firmly press it onto the required location. Keep the device and surface under this same pressure for approximately 20 minutes (to achieve 50% bond strength in room temperature).
Threaded M3 Holes
Suitable for optional pole mount bracket or mounting to an enclosure.
Side Mounting holes
Side mounting points designed for M5 countersunk bolts or screws.

Orientation & Magnet Location

The switch that the magnet (Part 4) operates on the Accelerometer (Part 1) is located between the STATUS LED and the COMMS LED indicated by the ‘X’.

Operating Instructions

Operation

By default, your Viotel Accelerometer Node will be set to Off. Wherever instructed to hold the magnet in place, do so at the spot indicated in section 2.2 Orientation & Magnet Location. Release from this position will send through the specified command.
At each function, the STATUS LED will light up once with its colour represented by its current status. All operations and LED indications refer to firmware version dated February 2023. Please be aware states may change some functionality between firmware versions.

HOLD INSTRUCTIONS	FUNCTION	DESCRIPTION
Hold 1 second	Current Status	This will light up the LED indicating the

current status that this system is in.
Hold 4 seconds| On/Off| This will stop all operations and switch the current status. While On:
In this status, the device will consistently record data given the user defined mode, check for firmware updates, monitor for user defined triggers and check for Magnet inputs (Part 4).

While Off:
The device will check for any wake-up commands, such as the Magnet (Part 4).
Every 7-days, the device will initiate a connection to provide status updates and check for system updates. Then it shall return to Off status unless otherwise specified by the server.

Modes

Trigger| The node will continuously monitor and collect raw data, sending data only once an event has occurred. State of health information is still sent at regular intervals.
This mode supports two trigger states:
Ratio of Averages:
The node will send data relating to a trigger caused by the exceedance of the ratio between the short-term average (STA) number of samples and the long-term average (LTA).
Fixed Value
The node will send data relating to a trigger caused by the exceedance of a predefined upper and lower threshold.
---|---
Continuous| The node will continuously monitor, record and upload raw data. State of health information is sent

Maintenance

The product should not require any maintenance after installation. If the need to clean the product should arise, use only a damp cloth and mild detergent. Do not use any solvents as this may damage the enclosure.
Only service personnel authorised by the manufacturer may open the inner enclosure. No user serviceable parts are located inside.

Changing Batteries

STEP	DESCRIPTION
1	Please ensure the node is Off before proceeding.
2	Using the T10 Torx Screwdriver, unscrew until the 4 bolts on the

front of the node’s enclosure are loose. Please note that the bolts are designed to remain in device section.
3| Flip over the top half of the enclosure making the battery pack is clearly visible. Position two fingers around the battery and firmly pull up; the battery should pop out of its holder. Ensure you do not pull or rip the red & black cables attaching the battery pack to the device.

4| Gently pull out the exposed plug connecting the battery to the device. Please dispose of this used battery pack correctly based on legislative requirements.
5| Gently push the new battery packs plug into the devices socket. A pair of thin needle nose pliers may be required to confirm it has been adequately plugged in.

6| Slide the battery pack into position and push firmly on the battery until it clicks into place.
7| Once the device is screwed back into the base, your node can be safely turned back On.

External Power

7.5V DC supply is required to power your device. All electrical work must be carried out by suitably qualified technician, and in compliance with local laws and regulations.
Power adapters can be purchased from Viotel.

Downloading Data

The only way to retrieve data is over the cellular communications. This can be activated on demand using the magnet. However, if the device is in the field and is unable to upload data, the device is programmed to keep trying in decreasing increments. If after 4 days of attempting to upload, it will reboot.
Data loss may occur during extended power loss periods.
Data is deleted from the device once successfully uploaded.
