Query: In Ground Alarm

I've installed inground alarms for customers. Pool Guard is the easiest to set up. I mount the alarm on 12x12 paver, so you don't drill in the deck. As much as the manufacturer says there are fewer false alarms, my customers tell me of false alarms. This the better of the less expensive alarms. Buy a door alarm and a pool fence.
