摘要： A smoke detecting apparatus includes a lamp, a light receiving element for receiving light from the lamp, and a smoke detecting circuit for detecting the smoke density in accordance with the signal outputted from the light receiving element. The apparatus further includes a light emission failure detector and counter for detecting a light emission failure in which the lamp fails to emit light in response to a light emission instruction from the smoke detecting and counting light emission failures, and a memory for storing the number of light emission failures. The apparatus may further include a warning unit which, when the number of failures becomes a predetermined value or more, warns that the lamp will soon be exhausted. Thus, the unit enables a maintenance person to replace the lamp without fail before it is exhausted.

摘要： A surge arrester disconnecting device which includes a fixed electrode, a movable electrode, and a latch device for holding the two electrodes in engagement. A trigger device, associated with a first spring and a fusible wire stretched between the movable electrode and the trigger device, releases the latch when the fusible wire is melted by continuation current therethrough. Upon trigger actuation and latch release, a second spring assists in the non-explosive disconnection of the movable electrode.

摘要： A photoelectric type fire detector includes self-testing capabilities. An upper level threshold limit and a lower level threshold define a predetermined range for output levels of an amplifier connected to an output of a light receiving element. In a self-test mode, a gain set in the amplifier is increased automatically. The number of times in which the amplifier output level deviates from the predetermined range is counted. If the deviation count exceeds a predetermined count threshold, it is determined that the photoelectric type fire detector is abnormal.
