<p>A home control device comprises terminals for connecting to a constant mains supply cable 22 and terminals for connecting to a cable 13 of a pendant light 14. The device comprises a plurality of receivers for respectively receiving audible and infra-red remote signals for controlling the light 14 and for controlling other appliances remotely connected to the device. The remote appliances are controlled by applying data signals to the mains cable 22 and/or to a radio carrier. The device further comprises input transducers 27,30 for sensing parameters such as sound, movement, temperature, smoke or humidity etc. within the room and means for activating alarms and other appliances e.g. 28,29 in response to predetermined signals from the transducers 27,30. The control device can conveniently be fitted in place of a conventional ceiling rose, which has the advantage that there is a readily available constant mains supply. The device is located at the point of the lighting fixture and thus the need for complicated and extensive wiring between the control device and the light 14 is avoided. Another advantage of mounting the control device to the ceiling is that it is located in a position which is high up in the room, where it is therefore able to receive remote control signals from almost any location within the room. <IMAGE></p> |
