A water-powered residential fire suppression and alarm system is provided. The system comprises a sprinkler head, a water-powered alarm, a fire-resistant transfer line assembly, and a housing assembly. The sprinkler activates upon excessive heat. The transfer line assembly provides an unclosable channel connecting an existing residential water fixture with the sprinkler head. The transfer line assembly includes a fire-resistant transfer line connected to a multi-port coupling which connects to the existing water fixture. The transfer line assembly also provides water to the alarm. The housing assembly has a housing with a vertical span of about 3-12 inches. The sprinkler head and alarm are mounted to the housing assembly and the transfer line assembly is connected to the housing assembly. When water is provided to the coupling and the sprinkler head activates, water flows through the transfer line, activating the alarm.

A method for improving the hit accuracy of fire detection systems controlled by infrared and video fire detection by means of a first IR/video camera system for the first detection unit (D1) to ensure continuous fire detection and a second IR/video camera system for the second detection unit (D2) to ensure automatic target tracking with respect to the source of fire, as well as to an extinguisher launcher (A) rigidly connected to the second detection unit. The method is characterised by steps through which video/infrared-controlled extinguishing systems can be precisely hit with regard to the target precision, and fires can be combated as quickly as possible, even in the early phase, with as little extinguishing agent as possible.

A sprinkler bulb 100 for a fire suppression system and a method of activating the sprinkler bulb 100. The sprinkler bulb includes a sealed frangible housing 110; a circuit device 120 within the housing 110, wherein the circuit device 120 comprises an ultraviolet light source 125; and a photosensitive fluid 130 within the housing that in use undergoes a chemical reaction when exposed to ultraviolet light from the light source 125.

A mesh network fire suppression system includes a coordinator node configured as a control unit. The coordinator node includes a transceiver, a processor, and a memory coupled to the processor. In addition, the system includes a plurality of sprinkler nodes configured to be positioned within a building and connected to a water supply, where each of the sprinkler nodes includes a battery as a sole source of power, a wireless transceiver configured to be in communication with the coordinator node, a sensor configured to sense environmental conditions, monitoring circuitry, and actuation circuitry. In addition, each of the sprinkler nodes includes a sprinkler head coupled to the actuation circuitry and configured to dispense water when actuated. The coordinator node is configured to transmit an actuation signal to the actuation circuitry to at least one sprinkler node in response to receiving an alarm message.

A sprinkler includes a frame, a deflector member, a sealing assembly, and a releasing mechanism for a controlled actuation. The releasing mechanism includes a hook member, a strut member, a load member, a link member, and an actuator. The link member surrounds or frames the strut and hook members and holds the members in a static relationship of an unactuated configuration. A preferred link member includes a single central slot through which each of the hook member and the strut member extend. The actuator is arranged with respect to the link member to separate the hook and strut members and break the link member upon operation of the actuator.

A fire protection system includes a pipe system in fluid communication with a water source. A local processing unit is operatively coupled to a radio frequency identification (RFID) tag reader antenna. Sensors monitoring a sensor area for the presence of a fire are in electrical communication with the local processing unit. Fluid distribution devices in fluid communication with the pipe system are configured to deliver water from the water source to the sensor area. An RFID tag apparatus is coupled to one of the fluid distribution devices and includes an RFID tag antenna positioned within the pipe system and is configured to transmit and receive radio frequency (RF) signals to and from the RFID reader antenna and local processing unit, through the pipe system.
