TWIG advantages

The TWIG advantage comprises durable and long-lasting devices combined with professional technical support and caring customer service. TWIG personal safety devices are cost-effective in the long run not only because of their durability and compatibility but also because of their scalability and modularity.


TWIG devices are compatible in many ways. Firstly, TWIG devices are easy to deploy with TWIG or third-party compatible systems or alternatively they can be integrated to a client monitoring software.

Second, TWIG compatibility includes a full range of accessories, short range devices and an alarms monitoring application TWIG WebFinder SP. Together, these form a wide product offering and build solutions to end-customer needs.

Third, TWIG over-the-air protocols are generally backwards compatible over evolving device platforms (device type TGP81EU to TCP90EU to TUP90EU). It means also novel TWIG devices are usually drop-in compatible with alarm receiving centre (ARC) systems once integrated with an earlier TWIG product.

Fourth, alternative TWIG personal alarm devices share a common ARC protocol, so you can integrate once and deploy different devices many times over (naturally only those device functions implemented in the integration will be supported by your ARC).

Scalable devices

TWIG device configuration scales through optional functions and widely customisable settings, according to project or customer-specific needs.

Open interface

All TWIG products can be integrated into customer or third party monitoring and tracking software. The open interface facilitates the integration of new functions and improvements, compatible with customer needs.

Modular system

The modular concept delivers cost savings and selectability for customers. The TWIG Short Range Device (SRD) feature is available as an option as it allows customers to build a complementary location system for indoor premises, and enables discreet alarms and registering attendance in changing indoor locations. TWIG with mobile SRD transmits alarms to the alarm receiving centre (ARC) over mobile network. TWIG devices integrate with the TWIG WebFinder SP as well as with customer monitoring software.

IECEx/ATEX compliance

TWIG Ex intrinsically safe models are approved to both ATEX and IECEx Australian/NZ standards for use in a potentially explosive atmosphere.

Indoor location

The TWIG Indoor lone-worker alarms system is designed to locate distressed or injured persons inside areas where GPS is not reliable and other methods do not provide needed accuracy. TWIG personal safety alarm devices report to your preferred receiving numbers or an alarm receiving centre (ARC). TWIG Beacon location information along with last known GPS position creates a complementary location system for indoor premises capable of global roaming outdoors.


TWIG com markets, engineers and manufactures reliable, durable and in the long term cost-effective personal alarms and takes care of our clients with professional support through the whole product life-cycle. TWIG products are engineered and manufactured in Finland in our own low-energy factory under an ISO9001:2015 and ATEX/IECEx compliant quality management system.

Quality is at the core of our identity. For us quality means saving time, money and environment and begins with a quest to understand customer needs. The exacting quality control followed in our factory means testing every single TWIG device for functionality, radio communications, location-finding sensitivity and waterproofness before delivery. Our warranty repair percentage is low. We specify and select components for device durability. All these factors contribute to trustworthiness of TWIG products, appreciated by our customers (source: Customer Survey 2015).


TWIG products are designed, manufactured and marketed pursuant to an ISO 9001:2015 certified quality management system. The notified body is VTT Expert Services (Technical Research Institute Finland).
