Hello all,
i am designing a simple fire alarm system consisting of some smoke detectors, and i control panel , so far i have one smoke detector which i have fitted with a relay.
the fire alarm circuit is going OK so far but i am using more relays then i would like to as i dont have enough and dont want to have to buy any, is there anyway i can use transistors instead? i have loads of diodes and loads of resistors and some transistors. the circuit is allot more complicated then it probably needs to be but any suggestions of how i can make it better would be much appreciated.
also, how am i going to get the relevant led light to come on when its detector is activated?
Please look and the schematic and i would be thankful of any suggestions of improvement, thanks,
