2N Sentrio is a state of the art emergency communicator enabling two-way visual communication for passengers and the call centre in an elevator entrapment emergency
With Sentrio, passengers can communicate by responding to questions sent by the emergency operator on the in-car display using either a touch-screen or tactile Yes/No buttons. Emergency call centre operators can verify the situation within the lift car by a remotely streamed view from the connected IP camera.
This gives vulnerable passengers reassurance that help is on the way, and helps call centres to quickly establish whether a rescue is needed especially when audio communication has not been successful.

Lifts using analogue ‘land lines’ will require a battery backed up 4G cellular or fibre VOIP system for safety and compliance
For decades, analogue copper phone lines have quietly served as the backbone of emergency communication in lifts — bringing not just connectivity, but power directly from the street into the lift car’s emergency auto dialler telephone. This meant no on-site batteries, no modems, and reliable operation even in a power outage. But as Chorus phases out the copper network across New Zealand, buildings are required to shift to 4G cellular or fibre-connected systems. Unlike copper, fibre doesn’t carry power — so lift emergency phones must rely on on-site internet equipment and monitored battery backups to stay online. Where this phone line is provided through the building’s fibre connection this will include conversion equipment such as ATA (Analogue Telephone Adapters) so that the installed analogue lift phones can continue to work.
Very often buildings are found to not have a UPS (uninterrupted power supply) for battery backup of important equipment. Furthermore battery backups require monitoring for the battery condition, and often have a maintenance requirement to replace the battery in as little as 2 years leaving another area of compliance and safety overlooked. The lift contractor may not have control or visibility of this equipment located elsewhere in the building, leaving a risk that maintenance and testing is neglected.
This is a fundamental change that introduces new complexity and risk, and building owners need to plan carefully to ensure compliance, reliability, and safety are maintained. On a positive note, 4G and VOIP based solutions are significantly cheaper than the existing copper lines, which cost upwards of $70 a month.
Louis Deverell of LDEV Tech has a decade of experience in implementing reliable connectivity solutions that do not rely on analogue telephone lines, and can function when critically needed in a power outage. Through a supporting division LDEV Connect, we can supply the industry with end to end products and solutions that include advice, hardware, with supporting SIM card and VOIP connectivity services. LDEV Connect supplies products from 2N, a leading global manufacturer of connectivity equipment. 2N products support cloud monitored connectivity to ensure the equipment is online and maintenance is up to date.
Solutions such as the 2N EasyGate IP capture the full requirements of a 4G Dual-SIM gateway that can provide the analogue telephone line to the lift car, and carry high quality phone calls over VoLTE or VOIP. This single device is capable of cloud connected monitoring and configuration, and importantly features a built-in battery. The device needs no connection to the building external to the lift installation, and simply requires a power supply.
