Up and running in just a few moments, Nirbi 4G Mains Power Failure Detector is a standalone mains outage detector that sends SMS and makes phone calls immediately after a power outage or recovery. Its innovative technology based on capacitors allows operation without batteries and therefore maintenance-free. The detector can be screwed to a wall or placed on a flat support. The initial configuration of the phone numbers to contact is done by sending a few SMS.


A power outage immediately triggers the sending of SMS and phone calls to one to five contacts. The detector is then powered by internal capacitors.


A power recovery immediately triggers the sending of SMS and phone calls to contacts. The internal capacitors recharge.


At any time, it is possible to obtain the status of the detector by sending it the character "?" by text message. It responds immediately with an informative SMS.




During configuration, you enter up to five phone numbers of people to contact during power outage or recovery events. For each number, it is possible to choose whether to send SMS and/or make a phone call.

By default, the SMS sent simply contains the power outage or recovery event. It is however possible to store in the detector during its configuration a free identifier (for example “TRANSFO HT NORD 4”) and a clickable geolocation link of the installation location (for example 48.85841, 2.29448 corresponding to the latitudes and longitudes of the Eiffel tower) in order to optimise the speed at which technicians respond when they receive the SMS.

Here is an example of a simple alert SMS, of an alert SMS with identifier and geolocation, of a telephone call then of a response to a status request.
