We recently installed a quality whole-house backup generator fueled by our home's gas system (also used for cooking, heating etc). Our generator will keep the house electrified even if the electric utility's lines are down.

Because the whole house electrical system is automatically backed up by the generator, it doesn't make much sense to install backup batteries in detectors that are hard-wired into the system.

Are we able to install new smoke and CO detectors that will NOT beep if no backup battery is on board?

I've seen and purchased detectors that were hardwire only. No battery. But the last time I tried to order I didn't see them listed. That doesn't mean they still don't make them. As far as battery backed up hard wired I don't know if they chirp with no battery installed at all as opposed to a weak battery. I've also encountered generators that didn't start when they were supposed to. Example: Starter failed, weak battery, and so on.
