First Alert SA710CN

If your home contains only ionization alarms that sense fast, flaming fires, experts say you'll need to add a few photoelectric models that better detect the smoke from slow smolders. Reviews are less plentiful for the latter type, but Consumer, a magazine based in New Zealand, gives high marks to First Alert Smoke Alarm with Photoelectric Sensor SA710CN. Owner reviews are scarce for this smoke alarm, but those we saw are extremely complimentary. A handful of owner reviews are found at Amazon.com, though most users don't indicate whether or not they've experienced fire or smoke in their homes. If you want an alarm that contains both ionization and photoelectric sensors, reviews most frequently recommend the First Alert Dual Sensor Remote Control Smoke Alarm SA302CN (*Est. $23).
