Why hasn’t anyone thought of this before
Conventional alarms depend on 120 v. If you loose power your pump also stops and the liquid level keeps rising. Battery power makes sense for emergency situations. Someone needs to build a battery operated alarm with a battery charger to keep the alarm ready if power is lost.
