Timed buizzer

I am trying to build a timed buzzer that sounds a buzzer for 5 seconds, a 15, or 30 minute pause and then sound the buzzer for 5 seconds again to end the cycle. The cycle needs to be started with a manual push button. Is the VM188 the right product for my needs, or is the a better choice?

The VM188 continously loops or does the cycle just once, so no, it is not the right item.
I’m afraid this calls for custom circuitry, which unfortunately is not something we can offer.

Is it possible to add an additional 5 second timer on the front of and in parallel with VM188?
