You can disable the alarm if you wish, however, it will not alternate if one of your pumps fail. The alarm is designed for a reason and in the case of the Zoeller 10-0804 Smart Pak Plus, multiple alarm modes will alert the user to potential problems and protect property by switching to the other pump when necessary. A built-in rechargeable battery will operate the alarm and LED lights for a limited time during power outage.
