Title: One worked, one nearly caught on fire...
Review: I purchased two of these, one for work which has been installed for over a year and works great (although since it is at work it could be going off daily with the alarms as others have mentioned), and one for home. I am just getting around to setting the unit up. I opened the unit and installed five alkaline batteries and started the setup process...it began smoking in my hands after only a few minutes. I disconnected the batteries and tried reinstalling the batteries but, now it won't operate. This is fresh out of the box...and I made sure the little switch for battery type was set to alkaline...this unit is going back.
