Renowned for global leadership in fire detection and suppression, Kidde
provides solutions ranging from portable fire extinguishers to advanced
industrial controls such as flame detection and explosion suppression systems.
Kidde is a UTC Fire & Security brand, with a history that's rich with
innovations, from the patent of the Chubb Detector Lock in 1818 to the
development of the world's first wireless networked smoke detectors in 2004.
The Kidde KN-COSM-B Battery-Operated Carbon Monoxide and Smoke Alarm combines
two important safety devices into a single unit. This alarm includes a voice
warning system that announces "Fire, Carbon Monoxide, Low Battery, or Smart
Hush Activation." The voice alarm eliminates any confusion and clearly
warns you and your family of a smoke or carbon monoxide danger, or if your
battery is in need of replacement. This unit uses three AA batteries, protecting
you and your family even during a power outage.
This alarm uses ionization sensing technology for the smoke alarm. Ionization
sensing alarms may detect invisible fire particles (associated with flaming
fires) sooner than photoelectric alarms. Photoelectric sensing alarms may detect
visible particles (associated with smoldering fires) sooner than ionization
alarms. Kidde strongly recommends that both ionization and photoelectric smoke
alarms be installed to help insure maximum detection of the various types of
fire that can occur within the home.
Combination Smoke/Carbon Monoxide Alarm
The Kidde Combination Carbon Monoxide & Smoke Alarm includes a voice warning
system that eliminates confusion and clearly warns you and your family of a
smoke or carbon monoxide (CO) danger, or if your battery is in need of
replacement or your alarm is in hush mode.
Fire: The red LED will flash and be accompanied by three long alarm beeps
followed by a verbal warning message "Fire! Fire!" The alarm will
repeat the pattern until smoke is eliminated. View movie showing voice warning
Carbon Monoxide: Four short alarm beeps followed by a verbal warning
"Warning! Carbon Monoxide!" This continues until the unit is reset or
the CO is eliminated. View movie showing voice warning
Low Battery: One chirp followed by warning "Low Battery."
The red LED light will flash. This pattern will continue every minute for the
first hour. After the first hour, the red LED light will flash once every minute
and will be accompanied by the chirp sound. The "Low Battery" warning
will only sound once every fifteen minutes.
Voice Hush Indication: "Hush Activated" and "Hush
Canceled" voice announcement.
Peak Level Memory: If the alarm had detected a CO level of 100ppm or
higher when the Test/Reset button is pressed, the unit will announce
"Carbon Monoxide Previously Detected" to warn of the CO incident.
Trademarked Hush Feature for Convenience
By pressing the Hush button, you can easily and safely silence nuisance alarms
caused by non-emergency situations, such as overcooked dinners.
This feature desensitizes the alarm for approximately 10 minutes. If the
smoke is not too dense, the alarm will silence immediately, the unit will
verbally announce "Hush Mode Activated", and the green LED will flash
every 2 seconds for approximately 10 minutes.
Reliable Battery Power, Indicator LED, Test Feature and Low-Battery Warning
The battery powered alarm provides continuous protection, even during power
outages. Because this alarm only helps protect you if it's working, this unit
features a red LED that flashes every 30 to 40 seconds to indicate that it is
operating correctly. For additional peace of mind, the alarm also contains a
test/reset button that enables you to periodically test its circuitry and horn.
If any form of battery failure is detected the red LED light will flash and
the unit will "chirp" one time, followed by the warning message
"Low Battery." This cycle will occur once every minute, and will
continue for at least seven days.
Seven (7) years after initial power up, this unit will "chirp"
every 30 seconds. This is an "operational end of life" feature which
will indicate that it is time to replace the alarm. UL 2034, the independent
standard applicable to CO alarms, requires CO alarms to have an end of life
warning. This requirement went into effect in March 2007, meaning any CO alarm
manufactured after April 2007 with a UL listing must have this feature. Most
states that require CO alarms in residential dwellings mandate that the alarm
meet the UL 2034 standard.
The unit measures just 5.75 inches in diameter and 1.7 inches deep, and it
features a neutral, white finish. It includes tamper resist features to deter
vandalism or theft. This combination smoke/CO alarm is UL listed, so you can be
confident of its quality, and it is backed by a 5-year limited warranty.
