Abstract
PURPOSE: To make other abnormal condition of other alarm item possible to be alarmed after the alarm is recognized by temporarily interrupting the alarm signal when after the alarm is recognized and, still another alarm item alarms the abnormality and detecting it.
CONSTITUTION: The bell Bl and the flicker relay Fl are actuated by turning ON the alarm item switches S1WS3 through the annunciator relay circuits AX1WAX3 every alarm item and the bell and the abnormal display lamps L1WL3 are illuminated. The switches S1WS3 are turned ON and the timer T is excited, after a predetermined time, the auxiliary relay X2 is made non-excited, accordingly, the auxiliary relay X1 is excited and the alarm signal is fed to a remote monitoring place. In order to recognize the alarm, the push button BS is opened, the lamps L1WL3 are continuously illuminated. Thereafter, when other switches are turned ON, the auxiliary relay X2 is excited, the auxiliary relay X1 is made from excited to non- excited and the alarm signal is interrupted. This interruption is equal to the time of T.
