The Kidde P4010ACSCO is an AC/DC powered, combination photoelectric smoke and carbon monoxide alarm that contains a 10-year, sealed battery backup and voice messaging system. The voice warning feature accompanies the 85dB tone during an alarm event, and helps reduce confusion with verbal announcements such as “Replace alarm” at end of alarm life, and “Hush mode activated” when a nuisance alarm is silenced.
This alarm uses breakthrough technology to offer a fast response to real fires, as well as protect you from carbon monoxide and dramatically reduce the chance of nuisance alarms. The Intelligent sensor technology combines the detection capabilities of a photoelectric smoke sensor with that of an electrochemical sensor, which is used to detect CO. Since carbon monoxide is present in all fires, having both detection chambers work together in one alarm is a breakthrough in the fire safety industry. When either sensor notices a potential hazard, it will communicate with the other. Depending on what is detected, the alarm will adjust its smoke sensitivity in order to better discriminate between a real hazard and a false one. This constant communication enhances the alarm’s overall performance in all fires, and significantly reduces the potential for a nuisance alarm.
Kidde P4010 Series Alarms contain 10-year tamper proof batteries that eliminate the need for battery replacement, and ends worry over unauthorized removal. Users are further shielded from late night battery chirps by the unit’s Ambient Light Sensing feature, which establishes a day / night cycle and prevents alarm chirping in dark conditions.

Feastures & Benefits

• Photoelectric Sensing Technology
• 10 -Year Sealed Lithium Battery Backup
• Voice Messaging System
• Ambient Light Sensor
• Smart Hush® Control
• Flashing LED Status Ring allows easy identification of current state of alarm

Install Confidence:
Voice Notification: Verbally announces “Fire!” or “Warning! Carbon Monoxide!” to help distinguish between threats.
Easy to Install: Backup battery automatically activates when the unit is attached to the mounting bracket
Photoelectric Sensor: Smoke sensor contains advanced photoelectric sensor that may detect visible particles (associated with smoldering fires) sooner than ionization alarms.
Ambient Light Sensing: Establishes Day/Night cycle and delays chirping during the night until the next Day cycle begins.
Test / Hush® Button: Tests alarm circuitry and activates Hush® feature to temporarily silence nuisance alarms for up to 10 minutes. End of Unit Life chirps can also be silenced.
End of Unit Life Warning: Alerts user the alarm is in need of replacement.
