    The BRK 3120B smoke detector from First Alert contains technology that many experts are now recommending -- dual sensors. A photoelectric sensor detects slow and smoldering fires, while an ionization sensor can detect often fast moving open flames. Your current detectors may have only one or the other, so if you're due (or overdue) for new ones, it might be something to consider. This model is hardwired with a battery backup (see below for non-hardwired model), so all units interconnect. When an alarm is triggered, indicator lights let you know which detector was the initiator, so there's no guessing. If being used in a public area, the BRK 3120B also has locking features that prevent theft of the battery or the unit itself. It averages 4.5 out of 5 stars from over 220 people (read reviews) and you can buy it now on Amazon for $29.97.
