Fire protection system

摘要

A fire protection system, having spaced outlet heads as water spray sources, the outlet heads having sets of outlet nozzles for providing concentric zones of water spray coverage, either 360 DEG or less than 360 DEG to achieve a generally uniform spray coverage for minimization and more effectiveness of water use. The outlets are adjustable as to both droplet size and direction of the spray dispensed; and remote control of actuation of individual outlet nozzles or of sets thereof further minimizes and makes more effective the water use.
