Wristband alerts: default settings and changing settings

Alerts can be adjusted to match your environment by changing the settings using the Proxxi Voltage App

When shipped, the wristband is at its most sensitive: 480V with alerts on. Being on the correct setting helps prevent nuisance alerts.

If your organization has custom settings, your wristband settings and/or sensitivity may be different than what is listed in this article. More information about custom settings can be found here.

Default Alert Settings

At 480V, the initial alert occurs at 45cm/18in* from an energized source and the high alert occurs at 30cm/12in.

Because the wristband senses any unshielded/ungrounded energy source, it will alert at further distances for higher-voltage equipment, and closer distances for lower-voltage equipment.

Adjusting Alert Settings

In the Alerts section of the Proxxi Voltage Mobile App, you can adjust the setting of the wristband to match your work environment.

At this time, the Proxxi Hub App cannot be used to adjust wristband settings

How to adjust alerts:

Navigate to the "Alerts" tab
Select new setting
Select "Confirm"
Set timer

Adjust Alerts Process

The timer is in place to ensure that you can’t accidentally leave the wristband on a setting that isn’t aligned with your next workplace.

At the end of the timer, the wristband will always switch back to the default of 480V with alerts on so that you have maximum protection.

Note: Voltage setting options in the video may differ from your app

The default setting options are based on the Limits of Approach as defined in NFPA 70e. We recommend that you select a voltage setting that is at or below the environment that you expect to be working with.

Avoiding Nuisance Alerts

Because Proxxi Voltage senses electric field strength, the wristband will alert for any ungrounded/unshielded source that emits a strong enough field. This means it will alert at close distances to items like laptops and power cords, or at further distances from powerful sources, such as overhead transmission/distribution lines.

The wristband senses the same intensity of electricity by being very close to a lower-voltage source as it would a 480V source at 18in/45cm* (if set to the standardized alerting parameters). An energized source does not have to be 480V (or your current set alerting parameters) for the wristbands to alert.

If you are not performing electrical work (during your commute or when in an office environment), we recommend muting the wristband to avoid nuisance alerts. Step-by-step instructions for muting alerts can be found here.

If working around equipment that is operating above 480V, you can adjust the wristband to a more appropriate setting.

It is important to note that 480V at 18in doesn’t mean 240V at 9in or 120V at 4.5in. Electrical intensity is dependent on the geometry of the source. Generally speaking, the electric field will fall off with the inverse square of the distance.

*Initial alert distances are applicable for wristbands shipped after 2023-05-19. Wristbands shipped before this date will perform the initial alert on the default 480V setting at 24in/60cm unless the organization has otherwise requested it
