Every second counts when it comes to house fires. This monitored detector has built-in photoelectric sensors for faster and more accurate detection. They are also less likely to trigger false alarms when you're cooking.
Once danger is detected, an internal siren will sound as well as trigger your alarm system's siren. Never worry about sleeping through a fire alarm again.
