    • In order to allow a smoke detector unit (1) to be utilised in, for example, a domestic kitchen environment, appliances (11, 21) whose operation is commonly associated with the generation of non-hazardous smoke or aerosols are connected to a conventional mains supply socket (7, 19) via a current monitoring unit (3, 15). The current monitoring units include a radio transceiver (13, 23) which transmits the operational status of the appliances (11, 21) to a corresponding transceiver (25) of the smoke detector unit 1. If the signals transmitted by the current monitoring units indicate that the appliances (11) and (21) are off, the smoke detector unit (1) generates a warning signal when the smoke density exceeds a lower threshold. If one of the appliances (11) and (21) is detected to be on, the smoke detector unit generates a warning signal only when a second, higher threshold of smoke density is exceeded. Optionally, when the higher smoke density threshold is exceeded, the smoke detector unit transmits the signal to the current monitoring unit to power off the appliances. The invention is also applicable to the detection of other characteristics of ambient fluid, such as temperature or the presence of a particular gas or vapour.
    • 为了允许在例如家庭厨房环境中使用烟雾探测器单元(1),其操作通常与产生非危险烟雾或气溶胶相关联的电器(11,21)连接到常规 电源插座(7,19)通过电流监视单元(3,15)进行。 目前的监控单元包括将设备(11,21)的操作状态发送到烟雾探测器单元1的对应收发器(25)的无线电收发器(13,23)。如果由当前监控单元发送的信号指示 (11)和(21)关闭时,烟雾浓度超过下限阈值时烟检测器单元(1)产生警告信号。 如果检测到设备(11)和(21)中的一个处于打开状态,则烟雾探测器单元仅在超过第二较高的烟雾密度阈值时产生警告信号。 可选地,当超过较高烟雾浓度阈值时,烟雾检测器单元将信号发送到当前监测单元以关闭设备。 本发明还适用于检测环境流体的其它特性,例如温度或特定气体或蒸气的存在。
