Abstract

A fire-extinguishing kit, system, and method for extinguishing fire in a chamber using pressurized dry fire-extinguishing agent. The system includes a plurality of pipes, each including a plurality of orifices, each orifice having a length L and a width W, such that L>W; a temperature sensor adapted to output signals relating to a temperature in the chamber; a pressurized reservoir containing the pressurized dry fire-extinguishing agent, and a controller associated with the temperature sensor and with the pressurized reservoir. In a monitoring mode, the reservoir is mechanically connected to the pipes, and in a fire-extinguishing mode the reservoir is in fluid communication with the pipes. The controller is adapted to receive an input from the temperature sensor, and, in response, to transition the system to the fire-extinguishing mode and to trigger release of the fire-extinguishing agent from the reservoir, via the pipes and orifices.

IPC Classes  ?

• A62C 3/07 - Fire prevention, containment or extinguishing specially adapted for particular objects or places in vehicles, e.g. in road vehicles
• A62C 35/02 - Permanently-installed equipment with containers for delivering the extinguishing substance
• A62C 37/40 - Control of fire-fighting equipment an actuating signal being generated by a sensor separate from an outlet device by both sensor and actuator, e.g. valve, being in the danger zone with electric connection between sensor and actuator

Abstract

A retrofit unit for retrofitting a fire extinguisher, the retrofit unit including a body portion, having a connector for connection to the fire extinguisher, an electronic pressure sensor, connected to the body portion, and adapted to sense pressure within the fire extinguisher, a processor adapted to control operation of the pressure sensor and to receive at least one pressure signal sensed by the electronic pressure sensor, a power source adapted to provide power to the processor and to the electronic pressure sensor. The retrofit unit may be fitted onto a fire extinguisher for measuring pressure therein, instead of, or in addition to, a mechanical pressure gauge.
