A method for extinguishing objects or appliances, in which, once a fire signal has been detected at point in time t1, a first device (17) providing an extinguishing agent is triggered, for discharging a liquid synthetic extinguishing agent (14), via a separating device (8), a common conveying pipe (9) and at least one nozzle (10), and, once a second fire signal has been detected at point in time t2, a second device (18) providing an extinguishing agent is triggered for discharging water (3) or a water-based extinguishing agent via the separating device (8), the common conveying pipe (9) and the at least one nozzle (10) for extinguishing. A system is also provided for extinguishing objects or appliances.

A fire detection and/or extinguishing control station for actuating two extinguishing agent supply devices using a control unit. After actuating a first extinguishing agent supply device (17) upon detection of a first fire signal at time (t.sub.1), the control station is additionally equipped to actuate a second extinguishing agent supply device (18) upon detection of a second fire signal at time (t.sub.2) if the control station has checked whether the time (t.sub.2) fulfills the inequality (t.sub.1+t.sub.c)<t.sub.2<(t.sub.1+t.sub.b), where (t.sub.c) represents a discharge time of the complete or partial discharge of at least one extinguishing agent container (1) of the first extinguishing agent supply device (17), (t.sub.k) represents a check time connected to the discharge time (t.sub.c), and (t.sub.b) represents a monitoring time period, and the monitoring time period (t.sub.b) is the sum of the discharge time (t.sub.c) and the check time (t.sub.k) beginning at time (t.sub.1).

Intelligent temperature and pressure gauge assemblies (52) for use with vessels (24) having pressurized hazard suppression materials therein include temperature and pressure sensors (136, 138) coupled with a digital processor (72) with associated memory for storing empirical temperature and pressure data. The data includes normalized linear temperature-pressure curves consistent with static or slowly changing temperature conditions experienced by the vessels (24), as well as nonlinear temperature-pressure curves consistent with rapidly changing temperature conditions. In use, the assemblies (52) repeatedly sense temperature and pressure conditions of the hazard suppression material and compare sensed values with stored values, and generate an output in conformance with the comparison. In this fashion, the assemblies (52) compensate for rapidly changing temperatures without generating false failure signals.

A valve arrangement includes a housing with an outlet and an inlet and having a poppet. The poppet has a stem and is movable within the housing along a movement axis between an open position and a closed position. The inlet is isolated from the outlet when the poppet is in the closed position. The inlet is in fluid communication with the outlet when the poppet is in the open position. The stem is inverted relative to the housing such that at least a portion of the poppet stem is disposed in the inlet when the poppet is in the open position.

A fire suppression system having a first triggering mechanism capable of being remotely triggered in response to a fire condition and a second manual triggering mechanism. More particularly, the fire extinguisher includes a valve for a fire extinguisher capable of manual and automatic operation. The system further includes a mechanism to notify of inoperable local status. During automatic operation, the system can be being triggered by a control panel in electrical communication, such as in response to a signal from smoke detectors. This system may also be manually triggered or in response to a temperature threshold sensor or other sensors. The valve includes an actuator that provides a separate area to place a safety pin for storing securely, and which provides feedback to the control system that the safety pin is properly stored and therefore, the fire extinguisher is active.
