Hey, I am making my own homemade fire alarm control panel, because i love electronics and fire alarms.
I have a 160 in one elecronics project kit and i have a relay which creates a latching circuit.
But now i want to create a delay circuit so that when i pull the alarm it waites 1-3 seconds before the alarm goes off.
I have 3 pull stations, 1 bell and 1 strobe connected to the board.
I do not have access to the 555 timer or any intergreated circuits (Yet) but i herd i could just use resisters and capaciters.
Anybody know how to do this, some instructions would be greatly appreciated.
Feel free to contact me through e-mail at: firealarmfreak@gmail.com
Thanks.
Chris.
