Hi everyone!
I'm a newbie here and I'd like to seek some help.
I need an alarm circuit (6-12VDC) interfaced with a 220VAC mains. The alarm circuit should set a load (relay) ON and trigger an audible alarm when the mains power is OFF. The audible alarm should be silenced/reset thru a momentary type pushbutton while the load (relay) should remain ON until the mains power has been restored.
I've devised an SCR circuit as the switching media and a transistor-based beeping alarm and a relay as loads, but I have problem silencing the alarm without disturbing the other load.
I'm not actually new to controls but basically I'm an "electromechnical relay (EMR)" guy who works on industrial motor controls and can setup the above circuit and practically any control logic thru EMR in no time.
But i'd like to "downsize" and do it in more economical way. And you guys are the best when it comes to these things.
Thanks in advance for your help.
