Portable plug-in version, A portable, visual smoke detctor. Perfect for small apartments, dorm rooms, etc. These stand alone units simply plug into a standard 110 volt wall outlet. Note: This unit is the same as the 710LS but has a 9 volt battery back-up. In the case of commercial power failure, the audible alarm will still work, but not the strobe. Helps to meet code in some areas. |
