Kidde Battery Operated Combination Smoke & Carbon Monoxide Alarm
KN-COSM-BA

Description

The Kidde KN-COSM-BA Combination Carbon Monoxide & Smoke Alarm provides two important safety devices in a single unit. This alarm includes a voice warning system that announces “Fire, Carbon Monoxide, Low Battery and Smart HushTM 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 technologically advanced combination alarm is battery operated protecting you and your family even during a power outage when many incidences occur.

The KN-COSM-BA is an easy to install alarm that is suitable for all living areas and has a 10-year life and a 10-year limited warranty. This alarm uses ionization sensing technology. Leading authorities 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.

Alarm Warnings

Fire:

The red LED will flash and be accompanied by three long alarm beeps followed by a verbal warning message “FIRE!”. The alarm pattern will repeat until smoke is eliminated.

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.

Low Battery:

If any form of battery failure is detected the red LED light will flash and the unit will “chirp” once every 60 seconds for at least 7 days. The “LOW BATTERY” voice occurs once every 15 minutes. The green LED will also be flashing twice per second.

Voice Hush Indication:

“HUSH MODE ACTIVATED” and “HUSH MODE CANCELLED” voice announcement.

Peak Level Memory:

If the alarm had 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.

Part Number (Ordering Number): 900-0102

• Voice Alarm – Announces the hazard type detected 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 hazard 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.

• Test/Reset Button – Tests alarm circuitry and triggers the voice announcement.

• LEDs – Flashing green for normal operation and flashing red for alarm condition.

• Low Battery Warning – The unit warns of a low battery condition by announcing “low battery” and by initiating an alarm chirp and activating a flashing red LED.

• Battery Powered – Provides protection even during power outages when many fire and carbon monoxide incidents occur.

• Battery Safeguard – The battery door will not close unless the batteries are properly installed.

• Hush® Feature – Temporarily silences nuisance alarms.

• Ionization Smoke Alarm Sensor

Technical Specifications

Architectural and Engineering Specifications

The combination smoke and carbon monoxide alarm shall be Kidde Model Number KN-COSM-BA (part number 900-0102A) or approved equal. It shall be powered by 2 AA batteries. The unit shall incorporate an ionization smoke sensor with nominal sensitivity of 0.97 %/ft. The CO sensor shall be of a fuel cell design and provide accuracy of +/-20% + 15ppm. The temperature operating range shall be between 40°F and 100°F (4°C and 38°C) and the humidity operating range shall be 10% - 95% relative humidity, non-condensing. The combination alarm can be installed on the surface of any wall or ceiling following the UL/NFPA/Manufacturer’s recommended placement guidelines. The alarm shall provide optional tamper resistance that deters removal of the unit from the wall or ceiling. The alarm shall include a test button that will electronically simulate the presence of smoke and CO and cause the unit to go into both modes of alarm. This sequence tests the unit’s electronics to ensure proper operation. The CO sensor will not alarm to levels of CO below 30 ppm and will alarm in the following time range when exposed to the corresponding levels of CO. 70 ppm CO Concentration 60 – 240 minutes 150 ppm CO Concentration 10 – 50 minutes 400 ppm CO Concentration 4 – 15 minutes The combination alarm shall have two methods of warning for danger: a piezoelectric horn that is rated at 85 decibels at 10 feet and a voice warning that identifies the danger. For a CO incident, the horn will sound in the repetitive manner -- four (4) fast beeps, a short pause, four (4) fast beeps, a short pause. In between, the unit will announce “Warning Carbon Monoxide!”. In a Smoke incident, the horn will sound in the repetitive manner -- three (3) beeps, a pause, three (3) beeps, a pause. In between, the unit will announce “Fire!” The unit shall also indicate a low battery warning utilizing each of the following methods: a brief alarm chirp, the voice announcement of “Low Battery!” and the red LED will flash once per minute. The unit shall incorporate 2 LED’s. A green LED will flash every 60 seconds in standby condition. A red LED will flash during smoke or CO alarm, and in error mode. The unit shall at a minimum meet the requirements of UL 2034, UL217, NFPA72, (chapter 11 2002 edition) The State of California Fire Marshall, NFPA101 (One and two family dwellings) Federal Housing Authority (FHA), Housing and Urban Development (HUD). It shall also include a 10-year manufacturer’s limited warranty.
