Connected emergency exits: greater safety with IoT

Monitoring emergency exits is critical to safety and a complex task. The mobile door monitor with NB-IoT enables real-time monitoring, centralised control and reduced administrative burden for building management.

“Our IoT solution provides maximum transparency regarding security-related door events – without the need for complex infrastructure. Operators can respond more quickly whilst making their processes more efficient.”

Axel Fischer, Geschäftsführer FiSCHER Akkumulatorentechnik GmbH

Three steps to an IoT use case

Challenge

Emergency exits must be accessible at all times in the event of an emergency, but must not be used without authorisation. Many companies still rely on stand-alone door guards that are not connected to digital systems. As a result, unauthorised openings often go undetected, there is no central monitoring, and critical conditions such as low battery levels are detected too late. This makes it difficult to implement security requirements reliably and efficiently, particularly in large buildings or across multiple sites.

Solution

The AlertLatch mobile door monitor from FiSCHER Akkumulatorentechnik GmbH combines mechanical security with smart IoT connectivity. As a networked sensor, it detects when doors are opened, triggers a local alarm and transmits events in real time to a central cloud platform. Data is transmitted via NB-IoT, a mobile communications standard developed specifically for the IoT, which ensures a stable and energy-efficient connection even in challenging environments such as basements or stairwells. Thanks to the integrated SIM card, no additional IT infrastructure is required. Deutsche Telekom provides the necessary network coverage and ensures reliable connectivity. This gives operators real-time insights across all locations and allows them to access all relevant data at any time.

Customer benefits

The solution provides real-time visibility of all door statuses. Unauthorised openings are detected and reported immediately, enabling operators to respond straight away. In addition, continuous status monitoring – for example, of battery levels – facilitates predictive maintenance. This reduces effort, minimises risks and sustainably improves operational reliability. At the same time, the solution forms the basis for connected building management in smart buildings.
