Combination Carbon Monoxide

& Smoke Alarm

Architectural and Engineering Specifications

The combination smoke and carbon monoxide alarm shall be Kidde Model Number KN-COSM-B (part number 900-0102) or approved equal. It shall be powered by 3 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 5% - 95% related humidity.

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 prop- er 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 dan- ger: 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! 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 incor- porate 2 LED’s. A green LED will flash when power is present. A red LED will flash once every 30-40 seconds to indicate the alarm is operating properly and will flash once per second when the unit is alarming and will remain so until the air is cleared.

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 5-year manufacturer’s limited warranty.

KN-COSM-B specifications

The Kidde KN-COSM-B is a sophisticated combination of a smoke detector and carbon monoxide (CO) alarm, designed to enhance safety in residential and commercial spaces. This dual-function device provides peace of mind by safeguarding against two of the most dangerous threats in any environment: fire and carbon monoxide poisoning.

One of the most notable features of the Kidde KN-COSM-B is its advanced photoelectric smoke sensing technology. This type of sensor is known for its quick response time to smoldering fires, which often generate large amounts of smoke without visible flames. This means that the device can alert users to potential fire hazards before they escalate, providing critical extra minutes for evacuation.

In addition to its smoke detection capabilities, the Kidde KN-COSM-B is also equipped with a reliable electrochemical CO sensor. Carbon monoxide is a colorless, odorless gas that can be produced by common household appliances like furnaces, water heaters, and gas stoves. The alarm features a loud 85-decibel warning signal, ensuring that occupants are alerted to the presence of CO promptly, allowing for immediate action to be taken.

The device is powered by a sealed lithium battery, which eliminates the need for constant battery changes, a feature that enhances its reliability. The battery has a lifespan of up to 10 years, aligning with the recommended replacement interval for smoke and CO alarms.

User-friendly features make the Kidde KN-COSM-B even more appealing. The unit includes a “test/reset” button, allowing users to easily verify the functionality of the alarm or silence it if necessary. It also features an end-of-life warning that alerts users when it's time to replace the unit, ensuring that safety remains uncompromised.

Another noteworthy characteristic is its sleek, compact design, which allows for seamless integration into various home décor styles without being intrusive. The device can be mounted on walls or ceilings, providing versatility in installation.

Overall, the Kidde KN-COSM-B stands out as a reliable solution for protecting families and properties from the dangers of fire and carbon monoxide. Its comprehensive features, coupled with user-friendly technology, make it an essential addition to any safety-conscious household.
