Event condition detection

A method of assisting rescuers to locate persons at risk in a structure, the method comprising:

• receiving at a sensory node, a plurality of condition data values from at least one condition sensor located at a first location in the structure;
• receiving at the sensory node, occupancy data from an occupancy sensor, the occupancy sensor located at a second location in the structure;
• transmitting by the sensory node, at least one condition data value and the occupancy data;
• determining a condition data threshold value;
• determining an expected condition data value for a certain period of time;
• receiving the at least one condition value and occupancy data by a remote computing device;
• determining a factor value representing a difference between the condition data value and the expect condition value for the certain period of time;
• transmitting an alert by the remote computing device as the result of the remote computing device receiving a condition data value that exceeds the condition data threshold value, the alert comprising a location associated with the received condition data value and received occupancy data;
• receiving, by a portable computing device, the alert;
• and
• displaying on a user interface of the portable computing device, a notification of the alert, the location associated with the received condition value and the occupancy data.

A device for assisting rescuers to locate persons at risk in a structure, the system comprising:

• a receiver;
• a processor;
• a user interface;
• and
• software, that when executed by the processor, causes the processor to:
• receive using the receiver an alert that indicates that a condition value exceeds a condition data threshold;
• receive occupancy data using the receiver;
• receive structure layout;
• display, using the user interface, a representation of the structure layout, an alert positioned on the representation of the structure layout such that the location from which the condition value was measured, and an indication of occupancy represented by an indicator positioned on the representation of the structure layout.
