I have 3 ea. 2GIG-SMKT3-345 installed for about 2 years now.
The one closest to the panel has been throwing a “malfuntion” error where it shows up and beeps on my Go Panel. This happens about every 2 weeks, but randomly and not at a set interval.
Last night I took it down and didn’t notice anything strange. I blew everything with air to try and clean.
My question is why do you think it is doing this? If the batteries were low, would it distinguish that with a low battery specific message?
