Hi Everyone,
I am after some help on circuit design for a problem I have with an alarm I have put together and wonder if anyone could point me in the right direction i.e. there maybe something out there already? However, if nothing off the shelf, or adaptable I am up for building something?
I have a mains supply into a PIR controller, which switches a seperate alarm bell. The reason for the help is when the mains supply to the PIR is lost for whatever reason, when the power supply is re-established, the PIR initially switchs until it resets itself and therefore the alarm sounds, which is what I want to avoid. Both PIR and alarm are 240V mains.
Hope this makes sense
Regards
