Hello Team. I have a very simple circuit. I1 is a smoke detector - NC I2 is a momentary push button for reset Q1 supplys power to external item Q2 supplys a fan and a green light Q3 is a sounder Q4 is a red light. Normal operation - q1 & q2 are going. Smoke is detected, q1 & q2 is switched off and q3 & q4 are on. Smoke clears q3 stays on until I2 is pressed then it returns to the beginning. Issue is, if the smoke detector I1 goes off again, it starts cycling through the whole series without needing reset I2 to be pressed. Is there a way I can stop I1 from doing this while also being able to have the ability to turn on q3 & q4 is smoke is detected again? Any thoughts and ideas would be appreciated. Thank you AttachmentCircuit Diagramupdatedtesting.zip (151 Downloads) |
