For unoccupied or large installations an on-site fault annunciator equipment is not sufficent. The supervisors must be informed continuously about the operation and failure conditions and if necessary to be able to take action also from the distance. For these requirements cost-effective SMS transmissions have established themselves, which are usable almost everywhere in the GSM net. The alarm activation is carried out via digital inputs, threshold crossings or gradient monitoring of analog inputs or about an individually parameterizable linking logic. Different reporting lines are available for notifications on different medias.
Basis for these device types is the approved MFW-Family.
