How long do the batteries in the wireless transmitters last and where do I purchase replacement batteries?
While the batteries will generally last 2-3 years, we recommend that you check the batteries in your wireless transmitters every 6 months (at the same time you check your smoke detector batteries is a great time to do it!). Each transmitter has a "test" function that you can use to test if the batteries and transmitters are operating correctly. Each transmitter uses two Duracell Type DL2032 "button cell" lithium batteries. They are widely available and can be purchased at any "Radio Shack" store, from us, or most other electronics retailers for less than $3 each.
Is the FloodStopper UL listed?
