Specification

Battery Operated Wireless Interconnect
Combination Carbon Monoxide, Fire & Smoke Alarm
Part Number 900-0225 Model KN-COSM-B-RF
Description
The Kidde KN-COSM-B-RF Combination Smoke & Carbon
Monoxide Alarm provides two important safety devices in a
single unit. This alarm includes a voice warning system that
announces “Fire”, “Warning, Carbon Monoxide”, “Low
Battery”, and “Caution, Carbon Monoxide Previously Detected.”
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 alarm can be installed as a single unit, or in a multiple sta-
tion configuration that will enable wireless communication with
the other alarms in the case of a smoke or CO event.
Installation of the interconnect system is quick and easy, and
avoids the hassle of extensive wiring and labor. Per NFPA guide-
lines, the interconnected system should not exceed the limit of
12 smoke alarms, or 24 total devices.
This alarm uses ionization sensing technology. Leading authori-
ties recommend that both ionization and photoelectric smoke
alarms be installed to help insure maximum detection of the
various types of fires that can occur within the home. Ionization
sensing alarms may detect invisible fire particles (associated with
fast flaming fires) sooner than photoelectric alarms. Photoelectric
sensing alarms may detect visible fire particles (associated with
slow smoldering fires) sooner than ionization alarms.
Features and Benefits
• Wireless Communication – Offers the safety benefits of an
interconnected system without having to run new wiring.
• Voice Alarm – Announces the hazard type thereby helping to
speed up the correct reaction to the hazard detected. Alarm
announces “Fire!” when a smoke or fire hazard is detected
and announces “Warning Carbon Monoxide” when a CO haz-
ard is detected.
• Combined Carbon Monoxide and Smoke Alarm – A single
unit can be installed where previously, two were needed.
Reduces installation time and helps to keep home décor
attractive.
• Peak Level Memory – If the alarm has detected a CO level of
100ppm or higher, the unit will announce “Carbon Monoxide
Previously Detected” to warn of the CO incident, when the
Test/Reset button is pressed.
• Silent Mode Feature – Temporarily silences nuisance alarms.
• Test/Reset Button – Tests alarm circuitry and triggers the
voice announcement.
• LEDs – Flashing green for normal operation and flashing red
for alarm condition.
• Battery Powered – Provides protection even during power
outages when many fire and carbon monoxide incidents occur.
• Low Battery Silence – Disable low battery chirp for 10 hours
without disconnecting power from alarm
• Ionization Smoke Alarm Sensor
• UL Listed
