I'm curious as to why the detectors have to be replaced every 10 years. 
Regardless, modern sensors could give a thermal map of the entire 
complex 24x7x365. Fire officials would have a better set of eyes when 
they showed up as the sensor system & network could provide thermals as 
a time series.

Also, another "killer app" for Boston is digital image correlation & the 
cameras monitor stresses and strains on historic buildings valued at 
about $10M each. And that's undervalued because they're really 
irreplaceable. Similar for some in the Netherladns. Monitoring the 
groundwater with samples every 4 mos is ok - better to monitor the 
structure itself 24x7x365.
