120V AC Wire-in Combination
Smoke & Carbon Monoxide Alarm
10-Year Sealed Lithium Battery Backup, Photoelectric Sensor
Model P4010ACSCO
Description
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.
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.
• 10-Year Limited Warranty
