FIRE SAFETY DEVICE AND FIRE SAFETY SYSTEM
TECHNICAL FIELD
The present invention relates to a fire safety device and a fire safety system including at least one of said fire safety devices.
BACKGROUND
When a fire breaks out in a building, there are a number of tell-tale signs. Often buildings have detectors to detect these signs and to activate an alarm. However, often due to a lack of interaction between detectors, alarms and extinguishers, there is a delay between a fire breaking out and the extinguishing of that fire. The present invention aims to reduce this problem.
SUMMARY
At its broadest, the present invention provides a combined detection and extinguishing system for use in buildings. Specifically, a first aspect of the present invention provides a fire safety device including:
a reservoir of fire extinguishing media; a detector arranged to detect signs of a fire; and an expulsion means arranged to expel, via an outlet, the fire extinguishing media from the reservoir on detection of signs of a fire by the detector, in order to extinguish the fire.
By having a combined detection and extinguishing system, the present invention reduces the need for human intervention which, for example, gives people inside the building a chance to escape without having to worry about putting out the fire themselves.
Optional features of the invention will now be set out. These may apply singly, or in connection with any aspect of the invention.
The fire safety device may include one or more, and preferably all, of a smoke detector, a heat detector and a carbon monoxide (CO) detector. By including all of these types of detector, it is possible to detect a fire e.g. before the temperature reaches a certain threshold or before there are excessive amounts of smoke, allowing for more swift and efficient detection of a fire. Furthermore, by including several types of detectors, it may be possible to detect more different types of fire, such as smokeless fires. The fire safety device may also include a means of manually activating the expulsion means, which may be part of the device itself, or may be located remotely, and activated e.g. via a wireless signal or a wired connection. In this way, in the event that the detectors fail, someone is able to manually cause expulsion of the fire extinguishing media.
In preferred embodiments of the invention, the reservoir, detector and expulsion means are integrated. By “integrated”, we mean that they are all formed as a single unit. The minimum separation between the detector and the reservoir is, for example, may be no more than 30cm, and more preferably no more than 20cm. In still more preferable embodiments, the minimum separation between the reservoir and the detector is no more than 15cm or 10cm. Having all the components integrated in the manner described above means that the fire safety device is in the form of a single selfcontained unit. This is more convenient, e.g. for installation. Furthermore, in the event of a fire, it means that the fire extinguishing media does not have to travel far before expulsion since it is located close by the detector.
For further improved convenience, the integrated fire safety device may include a single housing containing the detector, reservoir and expulsion means. The housing is preferably openable, in order to facilitate replacement of any of the components contained therein. This is discussed in more detail below particularly with reference to the reservoir.
For use in commercial buildings, it is preferable that the fire safety device is adapted to be ceiling mounted. To this end, the fire safety device may include supports for fixing the device to the ceiling. The supports may include clips or hooks, which may be adjustable. In particularly preferred embodiments, the fire safety device may be adapted to be recessed into a ceiling, so that the detector is exposed to the room below, and the reservoir is located in the cavity above the ceiling. This may be achieved, for example, by having two supports: the first set of supports arranged to attach the device to the ceiling of the room in which the fire safety device is located, the second set of supports being longer than the first set of supports and for attaching the device to the top of the ceiling cavity above the ceiling of the room in which the fire safety device is located. By attaching the device to both the ceiling of the room and the top of the ceiling cavity located above the ceiling, more secure attachment is provided, improving the overall safety of the arrangement. The second set of supports may include a chain secured to the fire safety device at one end and having an attachment portion at the other end for attaching the chain to the top of the ceiling cavity above the ceiling of the room in which the fire safety device is located.
In embodiments such as those described above, in which the device is adapted to be ceiling mounted, it is desirable that, on expulsion, the fire extinguishing media covers as large an area as possible. To this end, in preferred embodiments, the fire extinguishing media includes a liquid. Preferably, the fire extinguishing media is in the form of a fire extinguishing liquid. In such embodiments, to achieve the greatest coverage, the expulsion means preferably includes a sprinkler arranged to distribute the liquid over a wide area on expulsion. The expulsion means preferably includes a valve located between the reservoir and the outlet, the valve preferably arranged to open on detection of the signs of a fire by the detector.
The reservoir preferably includes a vessel, which may be made of metal or plastic, which contains the fire extinguishing media. The size of the vessel depends on the type of fire extinguishing media, but in the example of a fire extinguishing liquid, the vessel preferably has a volume of no less than 3 litres, so that there is sufficient liquid to cover the area covered by the fire safety device. The vessel may be no less than 3 litres in volume and no more than 9 litres in volume. As briefly mentioned above, the vessel is preferably replaceable. This means that the fire safety device can be reusable and isn’t defunct after a single expulsion of fire extinguishing media. In some embodiments, the vessel may be attached via a screw connection, though other types of connection are well within the remit of the skilled person. The fire safety device may include a pressure detector arranged to detect when the pressure in the vessel falls below a certain threshold, to warn when it may need replacement, or when there is a leak, for example.
In preferred embodiments, the vessel may be a pressurized vessel, in order that on expulsion, the fire extinguishing media leave the vessel at high speed to improve the distance covered.
Other than expulsion of fire extinguishing media, the fire safety device may be arranged to perform other functions on detection of the signs of a fire by the detector. For example, the fire safety device may also include an alarm configured to activate on detection of signs of a fire by the detector. Activation of the alarm may include one or more of: playing a sound such as a siren, playing a recorded voice message, displaying a flashing light. In this way, people may be warned of a fire, prompting them to evacuate or take other appropriate action. In some embodiments, a different sound/light may be played/displayed depending on what has been detected by the detector.
Along a similar vein, the fire safety device may have some kind of “smart” functionality. For example, the fire safety device may further include a smart module having a transmitter, which is configured to transmit a signal on detection of a fire, preferably a wireless signal, and in particular an RF signal (with a frequency of 3 kHz to 300 GHz). The signal may include information relating to the identity/location of the fire safety device, the nature of the detection (e.g. whether carbon monoxide, heat or smoke is detected). The transmitter may be arranged to communicate with a main hub located elsewhere in a building. In this way, a person who is responsible for fire safety in a building or perhaps the fire brigade can be made aware ofthe incidence and location of a fire immediately, in order to take the appropriate action. In order to power the transmitter, the fire safety device preferably includes a power source such as a battery, or it may be connectable to an external power source such as mains electricity. In embodiments in which there is a battery, the fire safety device may further include an alarm which is activated when the battery power falls below a predetermined threshold. Similarly, there may also be an alarm which may be activated when the fire safety device requires a service.
The fire extinguishing liquid preferably includes water. In addition to water, the fire extinguishing liquid may contain: (a) one or more of a phosphate, hydrogen phosphate or dihydrogen phosphate salt; (b) a hydrogen carbonate salt; and (c) a sulphate salt. Herein, phosphate, hydrogen phosphate and dihydrogen phosphate salts are salts including the anions PO43', HPO42' and H2PO4' respectively. A hydrogen carbonate salt is a salt including the anion HCO3'. A sulphate salt is a salt including the anion SO42'. Such a liquid demonstrates an improved ability to extinguish fires quickly and safely relative to known compositions, and is effective against a range of fire types.
For example, the fire extinguisher may contain diammonium hydrogen phosphate ((NH4)2HPO4), ammonium bicarbonate (NH4HCO3) and ammonium sulphate ((NH4)2SO4). Fire extinguishing liquid containing these compounds has been found to be particularly effective at extinguishing fires. In some embodiments, the fire extinguishing liquid may further contain monopropylene glycol (C3H8O2), which allows the fire extinguishing liquid to be used at temperatures as low as -20°C without freezing.
A second aspect of the system may provide a fire safety system for a building, the fire safety system including:
one or more fire safety devices according to the first aspect of the invention, each fire safety device including a transmitter configured to transmit a signal on detector of a fire by the detector of that fire safety device;
a hub including a receiver configured to receive the signals transmitted by the transmitter(s) of the one or more fire safety devices.
Systems according to the second aspect of the invention allow remote monitoring of all of the fire safety devices in a building. For example, the hub may include a display configured to display the information received in the signals, which may indicate to a user the identities/locations of the detectors which have detected signs of a fire. The hub may also be configured to display other information about the fire safety devices as well, in order to monitor the statuses thereof.
Further optional features of the invention will now be set out.
BRIEF DESCRIPTION OF THE DRAWINGS
Embodiments of the invention will now be described by way of example with reference to the accompanying drawings in which:
Fig. 1 shows a schematic diagram of a fire safety system according to an embodiment of the first aspect of the invention.
DETAILED DESCRIPTION
Fig. 1 shows a schematic diagram of the fire safety device 1 of the first aspect of the present invention. The view is a section through the device 1 in place mounted in the ceiling cavity C2 located between ceiling C1 and top surface C3. Broadly speaking, the device is divided into two parts 1a, 1b. Part 1a is located on the bottom surface of ceiling C1 and as such is exposed to the room R below. Part 1b is located inside ceiling cavity C2, and is hidden from view from the room R below. Part 1a includes a main housing 2 having a convex surface 2a which contains a plurality of holes 4 (the purpose of which are discussed later). The housing 2 and the lower surface of ceiling C1 define a cavity 3. The housing 2 is attached to the lower surface of ceiling C1 by the support clips 6. The clips 6 are L-shaped connected at one end to the main housing 2 and the horizontally extending portion are secured to the lower surface of ceiling C1 to support the device 1. In the embodiment shown, the support clips 6 may be adjustable. The cavity 3 contains detector module 8, which contains a smoke detector 8a, a heat detector 8b and a carbon monoxide detector 8c. As the names suggest, there are configured to detect smoke, heat and CO respectively. The holes 4 in the convex surface 2a ofthe housing 2 facilitate this detection. An alarm 10 is also located within the cavity 3, which is connected to the detector module 8. The alarm 10 is also attached to a power supply 12 which may be in the form of a mains connection or a battery. In the present embodiment, the power supply 12 is located above the housing 2, in the ceiling cavity C2 but in other embodiments, the power supply 12 may be located in the cavity 3. The detector module 8 is also connected to smart module 14. As with the power supply 12, in this embodiment, the smart module 14 is located in ceiling cavity C2, but in other embodiments, the smart module 14 may be located within the cavity 3. The main body of the device 1, and specifically part 1a is also supported by chain 16, which is connected at one end 16a to part 1a of the device 1, and at the other end, to the top surface C3 of the ceiling cavity C2. The chain 16 provides additional support for safety purposes.
Part 1b ofthe device 1, located in ceiling cavity C2 includes vessel 18, which contains fire extinguishing fluid (not shown). The neck 18a of vessel 18 is connected to one end 20a of conduit 20, the other end 20b of which is in fluid communication with cavity 3.
The conduit 20 includes a valve 22 for selectively providing and ceasing said fluid communication between the vessel 18 and the cavity 3. In the embodiment of Fig. 1, the neck 18a of vessel 18 is connected to the end 20a of the conduit 20 via a screw thread 24 to ensure a secure seal. To prevent leakage of the fire extinguishing media, the screw thread 24 preferably forms a watertight or airtight seal. The conduit 20 is preferably made of a strong, rigid, material so that the vessel 18 is supported in a horizontal position, as shown in Fig. 1. In other embodiments (not shown), there may be supports on the base of the vessel 18 or the vessel may be shaped to rest on the bottom surface of the ceiling cavity C2.
The operation of the device 1 will now be described. In the presence beneath the device
1, any or all ofthe smoke detector 8a, heat detector 8b and CO detector 8c may detect the relevant stimulus. On detection of the stimulus, the relevant detector 8 transmits a
Ί signal to the alarm 10, the smart module 14 and the valve 22. On receipt of the signal, the valve 22 opens, which results in fluid communication between the vessel 18 and the cavity 3. Accordingly, fire extinguishing fluid contained in the vessel 18 passes out of the vessel 18, flows through the conduit 20 and into the cavity 3. It then exits the cavity
3 via the holes 4 in the convex surface 2a of the housing 2. Because of the holes 4, the liquid is sprayed out over a larger area than if it were just e.g. a single hole. While this is happening, the alarm 10 may sound, and the transmitter 26 of the smart module 14 may transmit a signal identifying the device 1 and its location, and informing a main hub (not shown) that the fire extinguishing device has been activated.
While the invention has been described in conjunction with the exemplary embodiments described above, many equivalent modifications and variations will be apparent to those skilled in the art when given this disclosure. Accordingly, the exemplary embodiments of the invention set forth above are considered to be illustrative and not limiting. Various changes to the described embodiments may be made without departing from the scope of the invention.
