nope, you want an ionizing detector for earliest possible warning
I am surprised First Alert even makes a photoelectric-only sensor
I have their ionizing detectors and they work very well, I never had a false alarm

Photoelectric smoke alarms respond much faster (15 to 50 minutes faster) to smoldering fires – fires which move more slowly but produce the most smoke, the element of residential fires most responsible for fatalities – than ionization alarms.
Ionization smoke alarms generally perform slightly faster (30-90 seconds) to fast flame fires – fires with flames which spread quickly – than photoelectric alarms. The NFPA acknowledges that a well-designed photoelectric alarm will usually outperform ionization alarms in all fire situations, regardless of type and material.
