Abstract
A fire suppression system comprising at least one or at least two wall-mounted spray head units capable of aiming and shooting fire suppressant liquid into a fire is disclosed.
Claims39
A wall-mountable spray head unit comprising:
- a pivot base including a first path for fire-suppressant material;
- and
- a spray head assembly mounted on the pivot base configured so as to be rotatable about an axis between a first position and a range of second positions, the spray head assembly including a second path for fire-suppressant material;
- wherein the spray head assembly is arranged such that, in the first position, the first and second paths are not in fluid communication and, in the range of second positions, the first and second paths are in fluid communication.
A wall-mountable spray head unit comprising a rotatable spray head assembly which comprises:
- a spray manifold rotatable about a first axis and a spray nozzle supported by the spray manifold and orientated to deliver fire-suppressant material radially in a plane defined by the first axis and a second axis which is perpendicular to the first axis and at least one thermal sensor configured to sense in the plane;
- and
- a wipe station arranged to wipe away liquid deposited on the at least one thermal sensor.
A method comprising operating a spray head unit comprising a rotatable spray head assembly which comprises a spray manifold rotatable about a first axis and a spray nozzle supported by the spray manifold and orientated to deliver fire-suppressant material radially in a plane defined by the first axis and a second axis which is perpendicular to the first axis and at least one thermal sensor configured to sense in the plane, the operating comprising:
- in response to receiving a trigger, performing a scan for a fire;
- transmitting scan data to at least one other spray head unit;
- receiving scan data from the at least one other spray head unit;
- determining which of the spray head units is best placed to tackle the fire and, in response to determining that the spray head is best placed tackle the fire, rotating the spray head assembly to an angle for tackling the fire.
A method comprising operating a spray head unit comprising a rotatable spray head assembly which comprises a spray manifold rotatable about a first axis and a spray nozzle supported by the spray manifold and orientated to deliver fire-suppressant material radially in a plane defined by the first axis and a second axis which is perpendicular to the first axis and at least one thermal sensor configured to sense in the plane, the method of operating comprising:
- recording known heat sources and
- in response to performing a scan for a fire, taking into account the known heat sources.
A method comprising:
- closing or keeping closed a spray head;
- operating or causing operation of a pressure generator for a period of time;
- and
- measuring pressure in a feed line to the spray head or measuring an electrical characteristic of the pressure generator.
A method of operating a rotatable spray head or a system comprising at least two rotatable spray heads, the method comprising:
- determining if a temperature measured by a thermal sensor of the rotatable spray head or at least one of the at least two rotatable spray heads at at least one azimuthal angle exceeds a threshold;
- and
- in response to determining that temperature exceeds the threshold, triggering operation of a rotatable spray head.
A method of operating a rotatable spray head or a system comprising at least two rotatable spray heads, the method comprising:
- causing a pressure generator to pause and scanning so as to identify or confirm a fire, to choose a spray head to tackle the fire or both identify or confirm a fire and to choose a spray head to tackle the fire.
The method according to 23, comprising:
- triggering pausing of the pressure generator in response to sensor data and/or in response to an elapsed time.
A method comprising operating a rotatable spray head or a system comprising at least two rotatable spray heads, the method including:
- detecting obstruction of the rotatable spray head or one or more of the at least two rotatable spray heads.
A method according to 26, wherein detecting obstruction of the spray head or of the one or more of the at least two rotatable spray heads may comprise:
- using light, using ultrasound, or both.
