MT-514 – alarm system for lifts with 4G/VoLTE support for complete safety
Passenger safety and operational reliability are the foundations on which all modern lift systems should be based. Modern technology offers possibilities that allow for quick response to threats and remote monitoring of equipment status – without the need for a technician to be physically present. An example of such a solution is the MT-514 alarm module from Inventia – designed specifically for passenger and freight lifts. However, it can also be used in completely different areas, wherever voice communication is required in addition to monitoring and control using standard binary-analogue signals and a communication bus, e.g. in emergency call points or SOS columns on motorways.
Discover MT-514 – the intelligent solution for lifts
Future-proof connectivity with 4G and VoLTE
The MT-514 is equipped with a modem supporting LTE (4G) connectivity, making it a solution ready for the coming years. With the announced withdrawal of 2G and 3G technologies by mobile operators, 4G support is not only an advantage but a necessity for alarm systems to continue to operate without disruption in the future.
What’s more, the device supports VoLTE, a technology that allows voice calls to be made without switching to older network standards. This ensures high call quality, shorter connection times and full compatibility with modern operator infrastructure. This is particularly important in the context of alarm functions – contact with a person trapped in a lift or a service call must be immediate and reliable.
Remote diagnostics and real-time response
The MT-514 is not just an alarm system – it is an advanced monitoring and diagnostic tool. Thanks to NAT (Network Address Translation) support, it is possible to remotely connect to devices operating on the local network of the facility, such as the lift controller. This means that a service technician can check the technical condition of the system in real time, respond to a problem and, in many cases, even repair the fault remotely without the need for physical intervention.
This saves a lot of time and money – and, above all, ensures faster restoration of equipment efficiency, which is crucial in public facilities and residential buildings.
Versatile application and compliance with standards
The MT-514 is suitable for both newly designed installations and older lifts undergoing modernisation. Thanks to its compact housing and compatibility with popular intercom systems, it can be implemented quickly and without costly modifications.
Equally important, the device meets the requirements of the European standard PN-EN 81-28:2022-11 for alarm systems in lifts. This guarantees compliance with current regulations and peace of mind during audits and technical inspections.
Investment in safety and convenience
With features such as automatic alarm transmission, remote voice communication, message playback and audio loopback (path) testing, the MT-514 not only ensures user safety, but also convenience for technical staff. Its modern design and extended capabilities make it a natural successor to the popular MT-513 model, offering a number of improvements and an even higher level of reliability.
The MT-514 from Inventia is an intelligent, future-proof solution for lifts that combines modern 4G connectivity with VoLTE support and remote diagnostics. Thanks to this, the alarm system works quickly, stably and independently of older technologies that are gradually disappearing from the market. It is a tool that ensures passenger safety and facilitates the work of service technicians – today and in the future.
Frequently asked questions – MT-514
Will the MT-514 work when 2G and 3G networks are switched off?
Yes. The MT-514 is equipped with a modern modem supporting 4G and VoLTE technology, which means it is ready to work on the latest mobile networks, even after older technologies have been switched off by operators.
Can I install the MT-514 in an existing lift without replacing the entire system?
Of course. The module has been designed to work in both new and modernised installations. Thanks to its compatibility with “4+n” standard intercoms and compact design, its implementation is quick and does not require major changes to the infrastructure.
How does remote diagnostics work? Do I need to install an additional system?
No. The MT-514 allows remote access to devices installed on site (e.g. lift controllers) using the NAT function. You can connect directly to these resources to check their status and take appropriate action without having to physically visit the site.
Are voice connections stable and secure?
Yes. Thanks to VoLTE support, calls made via the MT-514 are fast, stable and offer high sound quality. The module can also play pre-programmed messages, receive and initiate calls, making it a fully functional communication system in emergency situations.
Does the MT-514 comply with applicable standards for lifts?
Yes. The device complies with the PN-EN 81-28:2022-11 standard, which regulates the requirements for alarm systems in passenger and goods lifts. This guarantees that the implementation of the MT-514 will comply with regulations and technical standards.
