Description of the Preferred Embodiments
The present embodiments represent currently the best ways known to the applicant of putting the invention into practice. But they are not the only ways in which this can be achieved. They are illustrated, and they will now be described, by way of example only. Any common features between the assemblies of the different figures are referenced by common reference numerals.
Standard light switch assemblies comprise a pattress box, also known as a wiring box or back box, for housing the electrical components, and a light switch which mounts over the pattress box and which includes the switching mechanism (such as a rocker switch, toggle switch, dimmer switch or push switch). The pattress box is sunken into the wall and has an opening for receiving electrical fittings, the light switch mounting over the opening. An exploded view of a typical light switch assembly 1 is shown in Figure 1. The assembly includes a pattress box 2 and a light switch 8, the light switch comprising a face plate 3 with switch mechanism 4 and a housing 9 mounted to the back of the face plate. In a standard light switch the housing 9 contains the electronics for controlling the power supplied to the light. In this example the face plate 3 has a push switch 4 to operate a light (not shown) between an on state and an off state.
The present invention provides a control unit that is sized and shaped to be installed into a standard pattress box for receiving inputs from one or more input devices, such as sensors, and for controlling one or more output devices. Pattress boxes for light switches are typically provided in a range of discrete depths, such as 16mm, 25mm, 35mm, 47mm. The control unit of the present invention is preferably sized and shaped to fit in a 25 mm depth pattress box. The control unit of the present invention is preferably sized and shaped to fit in a housing 9 of a light switch 8.
Referring to Figure 2, a diagrammatic view of a system incorporating a control unit according to a first embodiment is shown. The system includes a control unit 10 (not visible) installed in the pattress box (not visible) of a standard light switch 8. In this embodiment the system has a first input device (fire detector 20) and a first output device (light fixture 5) coupled to the control unit 10.
The light fixture 5 is powered by conventional AC household electrical mains power and the light switch 8 is installed so as to control passage of current to the light fixture 5, the light switch 8 being coupled to the light fixture 5 using existing wiring 6. The push switch 4 on the face plate 3 of the light switch 8 can be used to convert the light fixture 5 between an on state and an off state, as would be the case for a normal light switch.
The control unit 10 is paired with a fire detector 20, the control unit 10 and fire detector 20, preferably being configured to communicate via wireless transmission means, preferably radio frequency (RF) transmission means. However, other wireless transmission means may be used. The control unit may be adapted to operate according to the Zig Bee, Zwave, Bluetooth, or other wireless protocol. The control unit 10 can be configured to communicate with the fire detector 20 other than wirelessly, for example via optical or wired communication links.
Figure 3 shows a diagrammatic view of components that may be within the control unit 10 in a preferred embodiment and possible input and output devices that the control unit 10 can be configured to communicate with in different embodiments. Figure 3 includes a power supply 32, such as mains power, for powering the control unit 10 and some or all of the other devices in the system. The control unit 10 includes a processor 12, which may be configured to generate a warning indication in response to receiving an input from an input device. In the embodiment of Figure 2 the input device is the fire detector 20, and the control unit 10 is configured to generate a warning indication in response to receiving an input signal indicating that the fire detector has detected one or more predetermined conditions (such as presence of smoke, rate of rise of temperature above a threshold level etc). The control unit 10 also includes an RF module 14 or other communication means for communicating with any input device(s) and output device(s) that are configured to communicate with the control unit 10 via radio frequency communication.
When the fire detector 20 detects one or more predetermined conditions that are intended to give rise to a warning indication, the control unit enters a ‘fire mode’ in which control signal(s) are produced by the control unit 10 to generate the warning indication. In this example, the warning indication is provided by control of the light fixture 5 to convert the light fixture 5 to an on state (if it is in an off state). Research shows that the sound of conventional smoke alarms often fail to wake up sleeping children at night. A light switching on will provide a visual alert to occupant(s) that a fire has started. The triggering of the light fixture to convert to an on state will therefore provide an extra means for alerting sleeping occupants, increasing the chance that they wake up if a fire is detected.
In this example, the warning indication is provided by control of the light fixture 5 to convert the light fixture 5 to an on state, however the control unit can be configured to generate alternative or additional warning indications. For example, light switch 8 can optionally include a speaker 7 that sounds an audible alert when a fire is detected by the fire detector 20. In this case, the face plate 3 may have a grille 7a formed of a plurality openings in the face plate 3 to allow sound to travel out from the light switch face plate 3. When the fire detector 20 detects the one or more predetermined conditions that are intended to give rise to a warning indication and the control unit 10 therefore enters fire mode, a control signal is produced by the control unit 10 to activate the speaker 7. The control unit 7 may be configured to activate an electronically stored voice recording or synthesized voice that is played via the speaker 7. Research shows that voice alarms are more likely to waken sleeping children than conventional tone alarms. Of course, any audible alarm can be activated, including a voice or otherwise. The speaker 7 may be disposed separately from the light switch housing, but communicating with the control unit 10 as an output device.
Furthermore, the voice alarm may be configured to provide information, such as guidance on how to exit the building. This may be useful in systems in which there is more than one fire detector, each fire detector being in a different room or in a different part of the building. When the control unit 10 and fire detectors are installed, the fire detectors can be registered to the control unit 10 and identified with a corresponding location associated with each fire detector. For example, the control unit 10 can be calibrated by the installer to store within memory 13 an indication of where each fire detector is installed (eg.
downstairs or upstairs etc). Alternatively a radio frequency (RF) based tracking system could be used to identify the location of each fire detector incorporated in the system using RFID tags or similar mounted to each fire detector, the control unit being able to identify the rough location of each fire detector based on received signal strength. In this way, the voice alarm could provide audible instructions to occupants as to a safe exist route, such as to exit the home from upper floors, if a fire has started downstairs for example.
Referring to Figure 3, another warning indication that can be activated when the control system is in fire mode in addition to or instead of the warning indications described above is a means 16 for illuminating at least part of the face plate 3 of the light switch. In an exemplary embodiment, the control unit may be configured for coupling to a light source means or the control unit may include a light source means for illuminating at least part of the face plate 3. For example, the control unit 10 may be configured to activate red illumination of the face plate 3, or part of the face plate 3, when a fire is detected. This provides another visual alert that a fire has been detected. The light switch 1 may include a red light source means mounted behind a frosted diffuser forming at least part of the face plate for example.
The light source means may be configured to assume a predetermined colour when a predetermined input is received to the control unit 10 from the or a predetermined input device. Predetermined inputs can correspond to one of a set of two or more predetermined colours that can be assumed by the light source means. In this way, different statuses can be indicated visually to the occupant depending on the colour of the illumination of the face plate 3. The light source means may be a colour changing LED or set of colour changing LEDs that can assume different colours, depending on the output from the control unit 10, which in turn depends on the input received from input device(s). Alternatively the light source means may comprise a set of differently coloured LEDs, different LEDs being selectively activated depending on the input received by the control unit 10 from input device(s). The face plate may include an illuminating element such as a frosted diffuser forming at least part of the face plate, with the LED(s) mounted behind the illuminating element, the frosted diffuser glowing different colours depending on the colour of light that is activated. Table 1 below shows some example statuses that can be indicated by different illumination colours of the light switch.
Table 1
ILLUMINATION COLOUR | STATUS |
Red | For a system including a fire detector as an input device, the light switch can glow red if a fire is detected |
Blue | For a system that can interface with a mobile application (mobile “app”), the light switch can glow blue if activated through the app |
Green | For a system including a door or window sensor as an input device, the light switch can glow green if an open door or window is detected in the room |
Cool white | For a system including a doorbell as an input device, the light switch can glow white if the doorbell is activated |
For a system that interfaces with a mobile app, the light switch can be activated to glow (e.g. to glow white) via the app, for example to serve as a night light.
In preferred embodiments the control unit 10 can be configured to provide a first output or a second output depending on the duration of the actuation of the light switch 4. In this case the light switch will be a push button light switch or similar. In an exemplary embodiment, if the light switch 4 is activated for less than a predetermined duration, the control unit 10 is configured to activate or deactivate the light fixture (i.e. to control the on I off state of the light fixture). In other words, a short press of the light switch 4 will turn the room light on or off, as a normal light switch would when operated. If the light switch 4 is activated for a length of time that is more than or equal to the predetermined duration, the control unit is configured to enter fire mode, wherein one or more of the warning indications described above can be activated by the control unit. Therefore, an occupant can use the light switch 4, when coupled to the control unit 10, to activate the fire warning indication system by holding the light switch button 4 down for at least the predetermined duration (e.g. a predetermined number of seconds), even if the fire detector has not yet detected a fire. This provides an early warning system for other occupants in the building.
Control unit 10 can be configured to enter into a mode other than fire mode if the push switch 4 is activated for at least the predetermined duration. For example, in a building that has separate manual fire mode activation devices (e.g. a device with a panel that is shattered by a user to act as a manual fire mode activation device), then the control unit could instead be configured to enter a ‘panic mode’ in response to a long press of the push switch 4. When in panic mode, the control unit may cause a suitable output device, such as an audible alarm as an output device to sound that corresponds to panic mode.
As mentioned above in Table 1, the control unit 10 can be configured to interface with a mobile app. For example, referring to Figure 3, a remote device 34 such as a mobile phone or tablet computer with mobile app installed can act as a user interface comprising an input device that the control unit 10 is configured to communicate with, preferably wirelessly via the wireless module of the control unit 10. Acting as an input device for the control unit 10, a remote device with mobile app can provide an input to the control unit 10 causing the light fixture to be operated (i.e. to turn it on or off). A remote device with mobile app can be used to cause the control unit 10 to enter fire mode, thus triggering the one or more warning indications described above. For a control system configured to illuminate the face plate 3 of the light switch when the control unit 10 has entered fire mode, the control system may be configured such that the light source means assumes a different colour if fire mode has been triggered by the detection of a fire by the fire detector than if fire mode has been triggered by via the mobile app. The control unit 10 can also be configured to communicate with the remote device 34 as an output device wherein the remote device acts as a remote user display means for presenting status indications to the user as to the status of the control unit (e.g. if it has entered fire mode or panic mode etc).
Referring to Figure 4, another input device that the control unit 10 may be configured to receive input signals from is a doorbell 30. The control unit 10 may be configured to communicate with the doorbell 30 via wired or optical communication links or via wireless transmission means, as is the case with other possible input devices for the control unit
10. If the door bell is activated (e.g. by a visitor), the control unit 10 is configured to enter a doorbell alert mode. The processor 12 is configured to generate a doorbell alert indication in response to an input signal to the control unit 10 from the doorbell 30 indicating that the doorbell has been activated. When in doorbell alert mode, the control unit 10 is caused to control one or more output devices to generate the doorbell alert indication. A first doorbell alert indication may be the sounding of an audible signal via the speaker 7 of the light switch as an output device. A further or alternative doorbell alert indication may be activation of the light fixture 5 as an output device to flash on or to flash off, depending on the status of the light fixture when the doorbell is activated. This provides a visual indication that someone is at the door. A further or alternative doorbell alert indication may be activation of an illumination source means as an output device to illuminate the face plate 3 of the light switch (as mentioned above in Table 1). A further or alternative doorbell alert indication may be activation of a remote device as an output device to provide a suitable indication to a user of the activation of the doorbell.
The control unit 10 may include means for coupling to a microphone and a speaker (which may or may not be the same speaker that produces an audible alarm in certain modes of the control unit, such as fire mode) and for communicating with other control units 10 in the building, preferably wirelessly. In this way, the control unit 10 installed in a light switch can operate as an intercom system to allow an occupant to talk an occupant in another room or another part of the building.
The or each control unit 10 in a system can act as a wireless extender, such as an RF extender to avoid the need for separate wireless extender devices.
Referring to Figure 3, control unit 10 may be configured to receive signals from an occupancy sensor 22 as an input device for the system. In such embodiments the control unit 10 may be configured to provide an output to a remote device as an output device, such as a mobile phone or tablet computer with mobile app installed, to provide an indication as to whether the room(s) containing an occupancy sensor is/are occupied or not. Occupancy sensors such as passive infra-red sensors, or other suitable occupancy sensors may be coupled to communicate, preferably wirelessly, with the control unit 10.
The control unit 10 may be configured to receive signals indicating power consumption for the building, such as a wireless energy monitor 24 as an input device for the system. In such embodiments the control unit 10 will be configured to control a power consumption indicator 26 as an output device to indicate the power consumption for the building. The power consumption indicator could be light source means for illuminating at least part of the face plate of the light switch, wherein the face plate would be caused to glow at differing intensity levels depending on the power consumption detected. For example, the higher the power consumption detected, the higher the intensity that the face plate would glow. This can provide a useful visual indication of how much electricity a home is consuming.
The control unit may be incorporated into a light switch that has a standard face plate, the control unit being configured to receive inputs from the switch mechanism of the standard face plate. Alternatively the control unit may be provided with a dedicated face plate that is configured to be used with the control unit as the face plate for the pattress box.
The control unit may have one or more input devices and one or more output devices paired with it. It will be understood that input and output devices other than those shown in Figure 3 may be paired with the control unit. A building may have a system of multiple such control units, e.g. in different rooms.
Although in the preferred embodiment the control unit is configured for installation in a standard pattress box for a light switch, it can be configured for installation in other types of pattress box, such as for a pattress box for a thermostat or socket. It is especially useful for installation in a pattress box of a device that is already wired into a home’s mains system, therefore the control unit can easily installed using the existing wall fittings and be connected to existing wiring, and in order to communicate with any input or output devices as desired that are wired into the home’s mains system. Alternatively however, the control unit can be configured for installation in any suitable housing. Said housing can be configured to be wall mounted (e.g. sunken into the wall, rather like a pattress box) or otherwise.
