Checking the health of indicators

10 cells 9 alarm by pressing the button 8 control. When this buzzer 7

20 is disconnected from the signaling cell 9, and the indicator of the 10 signaling cell 9 is connected to the pulse generator 1. During the testing period of the indicators 10, through the contact of the control test button 8, the winding 15 of the relay is connected to the pulse generator 1, and a pulse, for example, of positive polarity, through the diode 22 and the differentiating circuit from the capacitor 19 and the resistor 21 is fed to the winding 15 of the relay, including it. The duration of the control pulse is chosen in such a way that the switch-on time of the relay is less than the pulse of positive (negative) polarity at the output of the pulse generator 1.

When the relay is turned on, its switching contacts 16 and 17 are switched, connecting the alarm cell 9 for a short time to the alarm indicator 7. And if at the time the indicators 10 are working, one of the objects changes its state, then through the switching contacts 16 and 17, the alarm indicator 7 will turn on signaling that one of the objects has changed its state. At the same time, it is necessary to interrupt the health check of the indicators 10 and release the control button 8. '
