What is a lone worker alarm?

A lone worker alarm is a technical aid used by individuals in need of added safety and security.

A lone worker alarm is essentially a piece of hardware that you can carry with you and that can be used to call for assistance, should you find yourself in an emergency situation. This somewhat broad definition includes a wide range of products suitable for different use cases.

We at SRT develop modern lone worker alarms  that utilize modern communication and positioning technologies and are often used together with a professional emergency service. The device provides geo-position data through the use of GNSS, radio signals or WiFi. Communication normally goes through cellular networks. Furthermore these kinds of devices are often equipped with various sensors in order to be able to detect and monitor user movement or objects in its surroundings.

When do you use a lone worker alarm?

Lone worker alarms are used when there is a risk of unforeseen, sudden and possibly dangerous situations arising. Modern lone worker alarms can even be configured to autonomously generate alarms, should the user be unconscious or otherwise incapable of doing so herself.

Who uses lone worker alarms?

Lone worker alarms are used by private individuals and professionals alike. Within certain occupational groups in Sweden the use of lone worker alarms are widespread. This can partially be explained by laws and regulations concerning work in hazardous environments. Examples of occupational groups where the use of lone worker alarms are especially prevalent are security guards, parking meter maintenance workers, shop staff, nursing and health staff and electric fitters.

How does a lone worker alarm work?

When you order a lone worker alarm from SRT or one of our resellers the device is configured prior to delivery according to your needs. This includes making sure it can connect to the emergency service center of your choice, configuration of the device and establishing an alarm procedure. If an incident should occur the user presses the alarm button, upon which a message is sent to the emergency service center containing the identity of the user and her position. Simultaneously a voice call is placed to the emergency service center allowing the operator on the other side to hear what is happening. Depending on circumstances and the severity of the situation, the operator makes sure that proper aid is provided. Additional information such as ICE (In Case of Emergency) contacts, visual description of the user and any medical conditions are provided to the emergency service center beforehand. That way the operator can decide what measures should be taken.
