Our solution enables organisations to protect lone workers and ensure their wellbeing as they operate in potentially hostile or dangerous working environments
Organisations can take advantage of the fact that Protect supports the widest range of lone worker specific devices on the market. This means that each lone worker can be provided with the device that fits their specific needs – and organisation are only required to work with a single vendor in order to do so.
The SOS Fob is undeniably the most popular device in the market, mostly due to it’s ease of us, discrete design and multi network roaming SIM that provides enhanced connectivity. However the wide selection of devices means that there is the right device available for every lone worker. View all our devices below.




Safe Hub App
Our safe hub app provides remote staff with the opportunity to use their standard mobile device as a lone worker safety device. Via a simple push of a button on their mobile phone, staff can immediately raise alarms and request support.
Key features:
- Red Alert (emergency): Press the Red Alert button to raise an alarm. This opens a two-way call with highly trained staff at an Alarm Receiving Centre (ARC), they will be able to deploy the emergency services.
- Yellow Alert (memo): Leave a voice message with task- or location-specific information. If the worker then raises a Red Alert or cannot be contacted their recording provides contextual information.
- Safe Check (proactive): Set timed welfare checks and reply ‘OK’ to the regular prompts. If the user doesn’t respond within the set period, a Red Alert is raised at the ARC.
- Worker Down (reactive): The handset’s motion sensors can detect an impact and Safe Hub will automatically raise an alert with the ARC.
- Group Alert (broadcast): Target warning messages at pre-defined groups, specific individuals, or users within a given radius from a central point.
- Safe Beacon (virtual barrier): When a worker enters an area monitored by Safe Beacon, an alert is sent to the worker and their line manager.
- GPS Locate (pinpoint accuracy): The lone worker’s GPS location is reported to the system every ten minutes as standard and whenever a Red, Yellow or Worker Down Alert is raised.
SOS Fob
The SOS fob is unarguably the most commonly deployed lone worker device and provides users with a BS8484:2016 Gold Certified personal safety device. Discrete, lightweight and durable the Fob can be worn by the employee via a lanyard or clip to ensure easy access when required, Utilising GPS and GSM technologies the SOS Fob enables organisations to locate lone workers, while also enabling staff to speak directly to an Alarm Receiving Centre (ARC), if they find themselves in danger.
This has been highly effective for major clients such as Centrica, Bristol Water, Essex County Council, NHS Trusts and Wessex Water, who collectively have over 10,000+ SOS Fob devices deployed across the country in rural and coastal areas.

SOS Button
The smallest and most simple of lone worker devices, the SOS button can be worn by a member of staff to alert others via a quick click of a button. The SOS button can be attached to a lanyard, clip or wristband to ensure it is easily accessible.
SOS ID Badge
The SOS ID Badge Alarm brings another level of discreet, wearable protection to Safe Hub. Particularly suitable for any role where some form of identification is required, such as a health or social worker, the ID badge doubles as a lone worker protection device. This slim and ultra-light device is easy to wear, using a clip or carrying strap. With GPS Locate, Red Alert, Yellow Alert and Worker Down fitted as standard, the device provides a broad range of support options.
Using GPS and GNSS (Global Navigation Satellite System) technology, a worker’s location can be pinpointed within moments. With its powerful hybrid communications technology, the device works equally well indoors and outdoors. When indoors or in a public location, it uses cellular, Bluetooth and Wi-Fi signals. Outdoors, it deploys 3-constellation GNSS service for a faster location fix. Whatever their situation, this will provide the right kind of help to lone workers as soon as they need it.
- Easily identifiable SOS key and ripcord alarm.
- Roaming SIM to maximise network coverage.
- Rechargeable battery gives up to 4 days of active use.
- LED display shows battery and connectivity status.
- Ultra-light (weighs just 74 grams).

Satellite Devices
SPOT Gen3
SPOT Gen3 is a satellite device that provides a critical, life-saving line of communication when ordinary phones won’t work. It’s an ideal solution for lone workers who travel into remote areas where mobile signals may be weak, intermittent or non-existent. Deploying GPS technology, the device automatically sends the user’s location information to the Alarm Receiving Centre (ARC) at 10-minute intervals. This information can be accessed by ARC operatives in an emergency, if the worker triggers a Red Alert.
SPOT X
SPOT X, the latest innovation from Globalstar, provides 2-way satellite messaging so lone workers can stay connected when they are in an area with poor or zero mobile signal. The device provides powerful communication in a crisis and allows the Safe Hub Alarm Receiving Centres (ARCs) to locate your workers if the worst happens. Deploying GPS technology, the device automatically sends the user’s location information to the Alarm Receiving Centre (ARC) at 10-minute intervals. This information can be accessed by ARC operatives in an emergency if the worker triggers a Red Alert.
ProtectMe
ProtectMe is a powerful GSM/GPS-enabled personal tracking device. Ideally suited to lone workers, the product is low-cost, durable and extremely easy to use. What’s more, it’s the most feature-rich dedicated device on the market and supports the full range of Safe Hub features.
ProtectMe’s screen allows users to choose their own safety interval on the proactive Safe Check feature. Additionally, in-built sensors raise an alert with the ARC via the reactive Worker Down feature if they detect a fall or impact. To maximise signal coverage even in areas of poor reception, we can supply ProtectMe with a roaming multi-network SIM.
Key Features:
- Red Alert (emergency support): Simply press and hold the SOS button to raise an alarm and immediately be connected with an ARC operative who will have access to their personal profile and GPS location. Calls are recorded and can include discreet panic words.
- Yellow Alert (voice memo): Leave a voice message, advising ARC staff that they are entering a potentially hazardous situation. In an emergency the ARC will access the recording along with the last known location, dispatching emergency support if needed.
- Worker Down (impact detection alarm): Safe Hub uses the motion sensors in ProtectMe to monitor the movement of the handset and its orientation. If, for example, the handset hasn’t moved for a length of time this could indicate that a lone worker requires emergency help.
- Safe Check (proactive support): Safe Check is a periodic welfare check. Once activated the platform will send a message for the lone worker to respond to at pre-determined intervals. Should the lone worker fail to respond, the platform will trigger an alarm with the ARC.

Intrinsically Safe Devices
These devices are ideal for lone workers operating in hazardous areas or extreme conditions. Intrinsically safe devices limit the use of electrical and thermal energy to a level below that required to ignite a specific hazardous atmospheric mixture.
At the same time, they’re top-of-the-range mobile phones, deploying GPS/GSM technology, and they provide excellent reception and coverage.
Our recommended devices support the full range of Safe Hub features. In the event of an accident or dangerous situation, the lone worker can manually press the emergency button to trigger a Red Alert at the Alarm Receiving Centre (ARC). Meanwhile, the in-built 3D sensors will raise a reactive Worker Down alarm at the ARC. And the device’s screen allows the user to set intervals for our proactive Safe Check feature, and to access Group Alert and Safe Beacon messages.
