An in-depth guide for the Twig One ATEX.
Twig One ATEX is an intrinsically safe personal alarm device, that is optimised for lone workers working in potentially explosive environments and meets relevant BS8484 criteria.
The diverse range of lone worker environments means a growing demand for lone worker devices, apps and accessories. The Twig One ATEX is a powerful lone worker device with high power speaker that boasts two-way communication and powerful vibrating and alerting alarms that help to notify lone workers of an alarm in noisy working conditions.
A simple press of the large panic button will raise an alarm in The OWL Portal and open an audio channel to our dedicated response team. If you don’t use our response team, LONEALERT will initiate the calls, SMS and email notifications that you have designated as part of your response.
The Twig One ATEX is ATEX/IECEx approved and can be used in hazardous and potentially explosive environments.
Allows lone workers to carry out their daily job role with added peace of mind, regardless of how noisy or dusty the working conditions may be.
Durable, rugged and waterproof with automatic ManDown detection on fall, tilt or impact.
On screen confirmation messages with built in GPS receiver and indoor location.
In many buildings the GNSS (Global Navigation Satellite System) signals are blocked and so the location of your lone worker is not known. The Twig One ATEX allows indoor locating through the SRD3 option which enables accurate location through using necessary bolt-ons such as RF Door tags, to record when rooms are entered and left, and beacons, to allow large areas to be subdivided. Both of which help you locate lone workers in need of assistance more quickly.
Powerful vibrating and alerting alarms to alert workers of preset alarms and incoming communications.
This device is fully customisable. The duration of the man down pre-alarm countdown can be changed depending on your requirements. It is also possible to customise the time between tilt detection and when the device starts to alert the user an alert is about to be raised. These are both set to 30 seconds by default. The device can also be set to VIBRATE for panic and alerts.
The Twig One ATEX is waterproof with protection against the effects from immersion of water, of up to 1m for 30 minutes. It's also dust tight, with no ingress of dust. The device also meets relevant BS8484 criteria.
Communicates with all systems using MPTP (mobile phone telematics protocol) both SMS and GPRS (IP).
Tracking and alert messages both include information on satellite positioning, TWIG SRD beacons and battery charge.
