A fire sprinkler emergency drain apparatus for conveying liquid from an open or leaking sprinkler head or leaking portion of a fire extinguishing system that includes a shallow mouth collection ring and drain line assembly having a collection ring of a size to surround a fire sprinkler head or a recessed opening in which a fire sprinkler head is positioned and a flexible drain line connected to the collection ring to convey liquid from the sprinkler head to a drain area, the drain line being mounted in a rolled configuration wherein the drain line is flattened in cross sectional configuration adjacent the collection ring and the shallow mouth collection ring and drain line assembly being supported by a handle adapted to be attached to a pole for use in elevating the shallow mouth collection ring and drain line assembly relative to a sprinkler head.

The invention concerns a method of checking the implementation of maintenance works in a fire extinguishing installation, wherein there is provided an identification (3) which contains a radio identification means, for example a transponder chip or an NFC tag which is fixedly connected to a unit (2) to be maintained so that the identification (3) cannot be non-destructively removed from the unit to be maintained, wherein the identification (3) contains data of the unit (2) to be maintained and wherein the unit to be maintained is part of the fire extinguishing installation and has to be uninstalled for maintenance, wherein there is provided a reading unit (8) with which the identification of the unit (2) to be maintained and the data thereof are read and wherein the identification (3) is arranged concealed or shielded on the unit (2) to be maintained in such a way that the data of the identification cannot be read with the reading unit (8) when the unit (2) to be maintained is in the non-uninstalled state.

Protective barriers are commonly installed beneath ceilings when construction work is performed either on these ceilings or on the roofs located above them. These protective barriers can be comprised entirely of one material or of different materials connected by seams. Some or all of these materials can be designed to fail when subjected to temperatures above a certain temperature range causing melting or some other destructive process to occur to these materials. These failures can create access points from the ceiling through the protective barrier to areas below being protected by the barrier, which can allow water from a fire suppression system, typically located near the ceiling, to reach a fire located below the protective barrier.

A pump panel training device is provided and includes a plurality of simulated gages operable to imitate gages upon a fire truck pump panel, a plurality of simulated controls operable to imitate controls upon the fire truck pump panel, and a simulated water hose operable to imitate one of water temperature changes, water temperature pressure, and water hose vibration for the fire truck pump panel.

Methods, systems, and devices for disrupting phenomena are disclosed. An example device can comprise a transducer configured to receive a signal and output a longitudinal wave based on the signal. The example device can comprise a wave enhancer coupled to the transducer and configured to direct the longitudinal wave into a form having lower attenuation in a medium than the longitudinal wave as output from the transducer.

Systems and methods for filling and pressurizing a container with liquid suppressant and nitrogen gas. A pressurized receiving container of nitrogen gas is initially provided at a transformative pressure and liquid suppressant is subsequently added to the pressurized receiving container. The transformative gas pressure provides a sufficient amount of nitrogen to saturate the added liquid suppressant and provide an operative head space pressure within the receiving container without the need for mechanized mixing of the nitrogen and liquid suppressant solution.

An illustrative embodiment disclosed herein is a network including a first local group of first node devices, a second local group of second node devices, and a new node device. The new node device has a processor with programmed instructions to range to each of the first node devices, collect ranging data from each of the first node devices, calculate a plurality of distances based on the ranging data, and send the plurality of distances to each of the second node devices.

A fireman positioning system includes: a first radio wave emitting device and a second radio wave emitting device, spaced with a predetermined distance and utilized for correspondingly emitting a first frequency modulated signal and a second frequency modulated signal; and a position receiving device, carried or worn by a fireman, and utilized for receiving the first frequency modulating signal and the second frequency modulating signal, and can demodulate the first frequency modulated signal via a first carrier signal so as to obtain a first output signal, and demodulate the second frequency modulated signal via a second carrier signal so as to obtain a second output signal, wherein a phase difference is formed between the first output signal and the second output signal, and the position receiving device can determine a direction angle of the fireman relative to the two radio wave emitting devices via the phase difference.

A warming system for protecting a fire sprinkler head during construction and demolition projects. The system includes an adapter attached to the sprinkler head, a protective cover that fits over the adapter, and a control system that is embedded in or attached to the protective cover. The control system includes at least one power supply, circuitry, a plurality of sensors, and an alarm.

A protective barrier that will typically be installed beneath ceilings during construction work being performed on ceilings or roofs of buildings. The protective barrier can be comprised entirely of one material or of different materials connected by seams. Some or all of these materials can be designed to fail when contacted by water via dissolution, melting or through some other destructive process initiated by contact with water. Some or all of the materials comprising the protective barrier can be designed to fail at a certain temperature. This failure can create access points from the ceiling through the protective barrier to the area being protected by the barrier, which can allow water from a fire suppression system to reach a fire located below the protective barrier.
