Abstract
A fire detection system comprises a plurality of individual fire detection-suppression units which all have their own individual standby electrical power supply. Each has a radiation detector for fire detection and its own source of fire suppressant. In the event of any of the units detecting a large fire, it automatically releases suppressant from its own source. In addition, all the units are connected to a master control station via a data bus. Any individual unit sensing a large fire signals this fact to the master control station which then enables the immediately adjacent individual units so as to permit those units, only, to release their fire suppressant if and only if they detect at least a 'small' fire (and also provided that the master control station determines that not less than a predetermined number of the units still have functional fire suppressant sources). There is thus a measure of central control and monitoring, and yet each unit is capable of operating completely independently in the event of its detection of a large fire. An emergency button provides a completely independent means of activating all the units. The master control station is also capable of activating all the units.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
