Kidde Smoke Alarm: Fast alerts with photoelectric sensing

Fewer false alarms from cooking, clearer warnings when it matters most.

Product Overview:

You want something that notices real smoke without nagging you every time dinner browns. This Kidde Detect smoke alarm uses a photoelectric sensor that focuses on smoldering smoke, so it skips most cooking fizzes and warns fast when danger appears. It runs on two AA batteries included, tests itself, and remembers if smoke was seen in the last twenty-four hours. The red LED flashes with three long beeps when triggered; a single chirp and amber flash tells you the battery is low. It even reminds you after ten years that it's time to replace the unit. Easy to mount with the twist-and-click bracket, no fuss.

Key Features:

• Photoelectric Sensor: Detects smoldering smoke quickly and, when triggered, flashes a red LED in sync with three long beeps until cleared.
• False Alarm Resistance: Enhanced sensing cuts nuisance alarms from cooking so you hear real threats, not burnt toast drama.
• Battery Backup: Runs on two AA batteries included, so detection continues through outages and you won't be left guessing.
• Quick Installation: Twist-and-click mounting bracket snaps on fast; install it in minutes without wrestling ladders or weird screws.
• Memory & End-of-Life: Built-in alarm memory and a ten year end-of-life reminder help you track unit history and replacement timing.
