Bests & Worsts Reviews from Amazon

Image stated 120db, where the insert with the alarms indicate 90db. Update: Failed pool inspection. Doesn’t come close to UL 2017 std. Alarms are of different decibels most under 85db. Has an on off switch which is not allowed, needs a bypass button. That being said they were easy to install, alert you when the door is opened and are small. If you are looking for alarms to pass UL 2017 code, you need either the Doberman or Techko. The UL 2017 cert should be on the packaging.
