Various embodiments include a fire detection system (FDS) device and methods for operating an FDS device to detect a potential fire and communicate information regarding fire detection events to a central fire detection system via a wireless communication network. Various embodiments include receiving information from one or more sensors configured to detect an indication of a possible fire, determining whether information received from the one or more sensors satisfy one or more threshold criteria indicative of a fire event, generating a fire warning message comprising a fire alarm object in response to determining that the information received from the one or more sensors satisfy one or more threshold criteria indicative of a fire event, and sending the generated fire warning message to a remote server via a communication network.

A mobile fire protection system comprises a first radiation detector for detecting radiation emitted by a flame in a monitoring region. A container holds fire suppression agent, the container being in selective fluid flow communication via a passage with an outlet for discharging the fire suppression agent. A mobile support structure carries the container. A valve is selectively movable between a closed state, wherein the fire suppression agent remains captive within the container, and an open state, wherein flow of the fire suppression agent from the container towards the outlet is enabled. A controller is configured, responsive to the first radiation detector detecting radiation emitted by the flame in the monitoring region, to cause the valve to move to the open state to discharge the fire suppression agent via the passage and the outlet towards the flame.
