The first fire extinguisher model sounds more dangerous than the fire: a cask that held liquid and a pewter gunpowder chamber connected to fuses. At the first flicker of flame, the alert 18th-century homeowner lit the fuses to ignite the gunpowder, which exploded, scattering the liquid retardant. Today, U.S. homeowners douse 13 million fires every year with extinguishers that use compressed air to spray foam, mono-ammonium phosphate or sodium bicarbonate. (via Popular Mechanics ) Important dates: 1723 (first fire extinguisher is invented); November 2017 (launching of PowaINFRA - an awesome Internet of Things).

When an ATM fails in is most likely to be one of the following causations: the utility power such as that supplied by the municipality or Eskom has failed; the ATM hardware has failed; and the network connectivity to the ATM has failed. In all cases a network management tool does not provide causation. The loss of connectivity to the ATM and the ATM infrastructure does not provide any measure of realtime diagnosis. Should power be restored the network management tool can potentially determine whether ther has been a power outage by referencing the system clock on the network equipment and determining if it has been reset. Some network equipment have a "last gasp" functionality, but in most deployment cases this does not function. The equipment failure is combined upstream with a service provider failure and the alerts are not received. The DS solution is to use a Powalert. The Powalert is an Internet of Things sensor that interoperates
