Preferred embodiments of the present invention will now be described, by way of example only and not in any limitative sense, with reference to the accompanying drawings in which: -Figure I shows a perspective view from the front of a unit in accordance with an embodiment of the present invention; Figure 2 shows a perspective view from the back of the unit of Figure I; Figure 3 shows a pcrspectivc vicw from thc back and one side, of the unit ofFigure 1, in situ on a wall mountcd clectrical socket; Figure 4 shows a schcmatic view of a first unit in accordancc with thc prcscnt invention; Figure 5 shows a schematic view of a second unit in accordance with the present invention; and Figure 6 shows a schematic diagram of a detection system in situ in accordance with an embodiment of the present invention.
Whilst the following examples refer to the detection of smoke, it is to be appreciated that the detection of other hazardous substances such as carbon monoxide, methane or sulphur dioxide, could alternatively be detected.
With reference to the Figures, a detection system for detecting the presence of a predetermined quantity of a predetermined substance is represented generally by reference numeral 1.
The detection system 1 comprises a first unit 3 and a second unit 9.
The first unit 3 comprises a body 4, housing a first detector 3a, an LED 3b, a device for emifting an audible alarm condition 3c, a power source in the form of a battery 3d, an associated battery charger 3e, a communications chip 31 a signal transmifter 3g and a signal receiver 3h. The first unit 3 also comprises electrical pins 5 for location with corresponding formations in a wall mounted electrical socket 7. The body 4 is adapted to removably connect with a separate electrical device (not shown) to facilitate the electrical connection of the separate electrical device with the wall mounted electrical socket 7.
For example, the body 4 comprises three channels 8 for receiving the three electrical pins of the plug of the separate electrical device. Tn this way, the first unit 3 acts as a "plug through" device, which enables separate electrical devices such as lamps and keftles, to be plugged into the electrical supply, via the first unit 3. The first unit 3 additionally comprises a heat detector 3j, which supplements the first detector 3a by way of detecting when the temperature of the surroundings reaches a predetermined level.
The second unit 9 comprises a body 10, housing a second detector 9a, an LED 9b, a device for emitting an audible alarm condition 9c, a power source in the form of a battery 9d, an associated battery charger 9e, a communications chip 9f a signal transmitter 9g and a signal receiver 9h. The second unit 9 also comprises electrical pins 11 for location with corresponding formations in a wall mounted electrical socket 13. The body lOis adapted to removably connect with a separate electrical device (not shown) to facilitate the electrical connection of the separate electrical device with the wall mounted electrical socket 13. For example, the body 10 comprises three channels 12 for receiving the three electrical pins of the plug of the separate electrical device. In this way, the second unit 9 acts as a "plug through" device, which enables separate electrical devices such as lamps and kettles, to be plugged into the electrical supply, via the second unit 9. The second unit 9 additionally comprises a heat detector 9j, which supplements the first detector 9a by way of detecting when the temperature ofthe surroundings reaches a predetermined level.
It is to be appreciated that the first 3a and second 9a detectors are each adapted to detect the presence of a predetermined quantity of any potentially hazardous substance such as smoke, carbon monoxide, methane or sulphur dioxide.
The power source 3d and 9d along with the associated chargers 3e and 9e, ensure that the units 3 and 9 still remain operational even in the event of a power failure in the electrical sockets 7 and 13 into which they are plugged.
It is also to be appreciated that the first unit 3 could be plugged into the wall mounted electrical socket 7 in a first room, for example the kitchen, and the second unit 9 could be plugged into the wall mounted electrical socket 13 in a different room, for example a bedroom.
With reference to Figure 4 in particular, the first unit 3, located in the kitchen, is adapted such that, in the event that the first detector 3a detects the presence of a predetermined amount of smoke, the signal transmitter 3g transmits a signal along the existing power line communications 20 in the building, connecting each of the electrical sockets together via an appropriate consumer unit 22. To elaborate, the electrical sockets in a house are each connected together via electrical wiring. In this way, in the event that a quantity of smoke is detected by the first detector 3a, thcn the signal transmitter transmits an electrical signal indicating an alarm condition, to the second unit 9 and any farther units plugged into the various electrical sockets (which are themselves electrically connected together) in the house, for example, in different rooms. Using the second unit 9, plugged into an electrical socket in a bedroom, as an example, the signal receiver 9h inside the body 10 receives the electrical signal indicating an alarm condition transmitted by the first unit 3, and initiates the generation of an audible alarm condition via the device for emitting an audible alarm condition 9c, and a visible alarm condition via the LED 9b. In this way, in the event that a quantity of smoke is present in the kitchen, then anyone present in the bedroom will also be alerted to the presence of smoke in the kitchen, both audibly and visually.
It is to be appreciated that the detection system could incorporate any number of units, for example, one in each room in the house having an electrical socket into which it can be plugged.
It is also to be appreciated that the devices 3c and 9c for emitting an audible alarm condition can be adapted such that they emit a typical piercing alarm sound. However, in this embodiment, the units 3 and 9 each include a slider switch 24 and 26 respectively, having settings for the various rooms in which the units 3 and 9 could typically be located. For example, in the event that the unit 3 is to be located in the kitchen, then the slider switch 24 on the unit 3 would be slid to the "kitchen" setting. On the assumption that the unit 9 would then be located in the bedroom, then the slider switch 26 on the unit 9 would be slid to the "bedroom" setting.
Thc units 3 and 9 arc adaptcd such that cach onc can bc prc-programmcd, using a recordable voice chip (not shown) for example, with suitable audible commentaries such as "thcrc is srnokc dctcctcd in thc kitchcn" and also "thcrc is smokc dctcctcd in thc bcdroom." In this casc, thc signal transmittcr 3g and 9g in cach unit is adapted to transmit electrical signals tagged with a particular unique identifier defined by the position of the slider switch 24 and 26, so that when the signal receivers 3h and 9h in the othcr units rcccivc thc clcctrical signal, thc idcntity of thc unit cmitting thc clcctrical signal can be ascertained. The communications chips on each unit can then look up the identity of the unit emitting the electrical signal in a pre-programmed look up table, and then initiate the appropriate audible commentary. As a result, the room in which the smokc has bccn dctcctcd can bc idcntiflcd, with thc result that cach of thc units can thcn emit the appropriate audible alarm commentary identifying in which room there is a problem.
Each unit is adapted to receive and transmit electrical signals, and also initiate an alarm condition, either audibly or visually, or both, via the LED or the device for emitting an audible alarm condition. In this way, each unit can independently detect smoke and initiate an alarm condition, as well as alerting the units in the other rooms so that they can do the same.
It is to be appreciated that the units 3 and 9, and in particular the bodies 4 and 10, can incorporate removable fascias having different colours and surface decoration, so that they can be removed and changed as desired by the user.
The units 3 and 9 each incorporate a test burton 30 and 32 respectively, which can be depressed at intervals to ensure that the device for emitting an audible alarm condition and the LED are both functioning correctly. The depression of the test button 30 and 32 once would initiate a three second burst of the audible alarm condition in the specific unit on which the test button being depitssed is located. Alternatively, the depression ofthe test button 30 and 32 twice in quick succession would initiatc a five sccond burst of thc audible alarm condition in each of thc units in thc system 2, simultaneously.
Thc units 3 and 9 additionally incorporatc a reset button 34 and 36 respectively, which allows thc uscr to silence thc dcvicc oncc thcy have cithcr dealt with thc situation or ascertained that it is in fact a false alarm.
The units 3 and 9 are each adapted to operatc at both 110 volts and 240 volts.
The system of the present invention benefits from the advantages that the units are completely portable, in that they may be taken on holiday for example, and plugged into the electrical sockets in for example, a holiday apartment or a hotel room. In this way, even if the apartment does not have appropriate detection apparatus, then the user can take the units along with them, for peace of mind. For example, the units 3 and 9 could incorporate a "travel adapter" function, whereby instead of the standard United Kingdom three electrical pin formation 5 and 11, the units 3 and 9 could alternatively incorporate a plurality of removable inserts (not shown) each insert incorporating the appropriate electrical pin formations for the US, Australia and Europe, for example. In this way, the units 3 and 9 could be taken on holiday along with the appropriate inserts according to the country being visited.
Moreover, the relatively low vertical height of the units 3 and 9 when in situ, when compared to known smoke detectors for example, which are typically located on the ceiling, means that the units 3 and 9 are more likely to resist the destructive effects of fire. For example, in the event of a quickly spreading fire, there is a possibility that a ceiling mounted smoke detector could be destroyed before it is able to warn the inhabitants of the building that there is a fire.
Further, the low vertical height of the units 3 and 9 when in situ, when compared to known smoke detectors for example, which are typically located on the ceiling, ensures that thc units 3 and 9 arc acccssiblc by a whcclchair uscr, thcrcby aligning thc dctcction systcm 1 with thc Disability and Discrimination Act (1995) Ruics.
Thc systcrn of thc prcscnt invcntion bcncfits from thc furthcr advantagcs that thcrc is no tirnc consuming and costly installation rcquircd, with thc units 3 and 9 bcing casily plugged into an electrical socket wherever detection is desired.
Moreover, as well as providing dctcction of a hazardous substance, thc system 1 of the present invention provides the user with additional information concerning the room of origin of the hazard, for example, the room where the fire has started.
It will be appreciated by persons skilled in the art that the above embodiments have been described by way of example only, and not in any limitative sense, and that various alterations and modifications are possible without departing from the scope ofthe invention as defined by the appended claims.
By way of example, the units 3 and 9 could additionally incorporate a wireless transmitter which sends a wireless signal to a remote wireless receiver (which can be for example, incorporated within a remote monitoring system) in the event that an alarm condition is detected. For example, the wireless transmitter could be adapted to transmit a wireless signal to an external alarm control box, which is adapted to initiate an alarm signal externally to the building, for example, in an external wall mounted box, which alerts external passers by to the fire inside the building. The alert could take the form of, for example, a flashing light (of a different colour to the burglar alarm flashing light) or an audible alert.
Further, the system I could be adapted such that as well as being able to transmit electrical signals along the existing hard electrical wiring connecting electrical sockets together, to other units of the system, the units can additionally transmit electrical signals along the existing hard electrical wiring to a remote router, electrically connected to a computer for cxamplc, computcr, which itself is adaptcd to facilitate external access to thc alarm condition via, for example, email, text or web acccss.
Furthcr, thc units 3 and 9 could additionally incorporatc an inscct guard to protcct thc intcrior of thc units 3 and 9.
Further still, the system 1 could additionally incorporate a mobile telephone charger including an integrated signal receiver, which, whcn plugged into a wall mounted electrical socket for example, and electrically connected to a mobile telephone, is able to receive any electrical signals transmitted from the units 3 and 9 and initiate an automatic call to, for example, the fire service or a call centre who would check the integrity of the alarm condition before themselves contacting the fire service.
