I wasn't asking how you actually do the flushes when I sent my reply to Brandon, but wanted to see if there was an override for the alarm for when you do. We do all the eyewashes in our chemistry labs weekly and the showers are tested 2 x a year for the 30 gallons per minute flow and flush. We have the technical staff do all the eyewashes, so doing them at 9 pm would not be an option.
My $0.02:
I can see more problems with a complicated system such as what he describes than it being worthwhile. When I was in chemistry as a technician, I liked keeping things simple in case I wound up being the person having to do the upkeep and maintenance, as we don't always get Facilities staffing to take care of these things. Those institutions with larger staffing and support from your Facilities may have better luck. When we built our new science center, I fought hard against some complicated systems the architects and lab designers wanted to put in as I knew we could not dedicate extra staffing.
Good luck,
Vivian
My facility manager created a very nice shower test rig here:

The shower curtain-like set-up on a pole was purchased commercially – the bottom is weighted to keep it inside the bucket.
We don’t test to “30 gallons/minute” – that’s the plumbing shop’s responsibility in their annual inspection.
FWIW,

They do make safety shower testing kits, on wheels even. See
