Bypassing And Re-arming PLEG

I’ve got a PLEG device that I have configured to only run hen armed. I want to be able to bypass the PLEG device manually, but have it automatically re-arm several hours later. I suspect a scene could do it, but I wonder if another PLEG would be better in order to avoid lost timers. What’s the best course?

A PLTS device can arm/disarm itself. The ARM condition will fire even if disarmed.

I might add that Reserved condition name to PLEG as well … So you can do this from the same PLEG.
