Good morning, All

I have an alarm pipeline with a notification block who's output feeds back into a delay block. I am seeing a doubling of alarm notifications every time an active alarm leaves the delay block and re-enters the notification block e.g. 1notification, then 2, then 4, then 8 and so on (for the same alarm). Why am I seeing a doubling of notifications, rather than a single 're-notification' of a still active alarm? And is there any way to prevent this doubling of notifications? As always, any help is greatly appreciated.

both your notification blocks are feeding the delay, so each time you go thru your notification block, you're sending 2 Delays, which then starts 2 splitters... round and round.

So, if I want to resend the notifications after the four-hour delay, I should go from the Delay Block 'OUT' directly to each Notification Block 'IN'??

Ended up feeding each notification block back into its own delay block and only fed the splitter once (at the beginning). Thank you for your help @tgarrison !!
