Depending on the nature of your business and your industry, there may be occasions where workers need to operate alone.  Ensuring the safety of anyone likely to be working without physical assistance is paramount.  You need to know the members of your team – whether out in the field or in-house – have access to the best systems and technology available. Many of the two-way radiosPTT-over-Cellular (PoC) devices and apps Umoja Technical Services Limited offer feature some kind of lone worker monitoring functionality.

How does the lone worker function work?

 How lone-worker mode operates is very straight forward. When lone-worker mode is active, a silent timer will start, counting down based on a period of inactivity on the device (ie. No button presses or calls made). This is sometimes known as a “check-in” or “keep alive” timer and Umoja Technical Services Limited recommend this is set to 30 minutes in the majority of cases. When the timer reaches a set point in the countdown, the device will beep or vibrate to request the user presses a button on the device to re-set the timer.

By doing this, the user is effectively confirming that all is well. This period is known as “pre-alarm”, and Umoja Technical Services Limited usually recommend a 2-minute pre-alarm window. If the user does not press the button within the pre-alarm window, an emergency alarm will be raised. This emergency alarm can alert a control room, other device users or external on-call personnel. With certain devices and apps, the emergency alarm can be accompanied by location information and/or by opening the microphone on the device, allowing responders to hear what’s going on.
