Query: Wireless system works well. Unit does not reset automatically when hushed

I've had these for several months, and the wireless system works well. One of the units is in my detached workshop about 75 feet from the house and the wireless connection has worked perfectly.There is one thing I am not completely happy with: when I hush one of the units because the barbecue set it off, it stays hushed apparently forever until I manually reset it. Every other alarm I have had resets itself after a time period. This one has a flashing indicator light that tells you it is hushed, but it's easy to miss and easy to forget what 1-second, 2-second and 10-second flashing means. I also think there is some complication if unit A is triggered and you hush by pressing the button on unit B.Also, in my community, photoelectric or combination units are required, not ionization units like this one. You may want to wait until they come out with other models.
