Abstract
An activator for a pilot type firefighting system for accelerating firefighting system activation is disclosed. The system comprises a control valve which acts to control firefighting fluid flow to a distribution system, and configured such that release of pressure to a control chamber would activate the control valve. The activator comprises a first chamber in fluid coupling to the pilot fluid and a second chamber in fluid coupling to the pilot line via a flow restrictor. A pressure sensing member is disposed such that pressure difference between the chambers would cause an activation of a switch. The release of the switch directly or indirectly causes activation of an electrical valve which vents the pressure in the control chamber. Several aspects of the invention include various firefighting arrangements, various optional features of the activator, firefighting system, and several methods of operation of a system utilizing the activator.
