Features
The KN-COB-IC is an essential device to help warn you and your family of dangerous carbon monoxide levels in your home. This alarm measures the exposure to carbon monoxide over time; it is designed to sound at 85 decibels at 10 feet when it detects 70 ppm (parts per million) of CO for 60 to 240 minutes, 150 ppm for 10 to 50 minutes, or 400 ppm for 4 to 15 minutes. The added benefit of being able to interconnect this unit with up to 23 other Kidde devices—such as other CO alarms, smoke detectors, and heat sensors—all on one wiring network delivers extensive protection against fire and carbon monoxide (as well as peace of mind). The 9-volt battery backup provides continuous security if the power goes out. An LED lighting system on the unit signals power levels and sourcing: The green LED is steadily on when AC power is present and will flash every 7 seconds when in battery-only mode; the red LED will flash in unison with the sounder pattern for both a smoke or CO incident, and it will flash once per 30 seconds if the alarm needs service or be steadily on if the alarm is in error mode; and the amber LED will illuminate if the unit is the originating alarm in a CO incident. This device has an expected 7-year lifespan and comes equipped with a 5-year manufacturer’s limited warranty.

Item Package Quantity:1

Flashing LED Status Ring allows easy identification of current state of alarm 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. Photoelectric Sensing Technology 10 -Year Sealed Lithium Battery Backup Voice Messaging System Ambient Light Sensor Smart Hush® Control Flashing LED Status Ring allows easy identification of current state of alarm

Product Description

The First Alert BRK SC7010B Hardwired Smoke and Carbon Monoxide Alarm includes a battery backup so that it keeps monitoring safety even if there’s a power failure. It’s designed for residential use as well as for institutional locations such as hospitals, hotels, dorms, and multiple-family dwellings. This alarm is interconnectable and can be linked with up to 18 compatible devices (up to 12 smoke alarms and 6 compatible devices like bells, horns, and repeaters) so that when one triggers, all alarms sound. This alarm emits a loud, spread-spectrum 85-decibel alarm designed to be heard even by those with some hearing issues. In addition to electrochemical CO-sensing technology, the detector also features a photoelectric smoke sensor that can help detect slow smoldering fires. One button silences any nuisance alarms, and also tests detector functions, while lights indicate if the alarm detects smoke or carbon monoxide. The latching alarm indicator automatically identifies which unit initiated the alarm, even after the conditions that set off the alarm have subsided. And an end-of-life signal enhances your safety by letting you know when it’s time to replace the unit. Hook up to AC power with the “quick-connect” wiring harness for easy installation.

The unit shall provide optional tamper resistance that deters removal of the unit from the wall or ceiling. No additional pieces shall be required to activate this feature. A maximum of 24 Kidde devices can be interconnected in a multiple station arrangement. The interconnect system must not exceed the NFPA (National Fire Protection Association) limit of 18 initiating devices, of which 12 can be smoke alarms. With 18 initiating devices (smoke, heat, CO, etc), interconnected, it is still possible to interconnect 6 strobe lights and or relay modules. 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! Fire!” The unit shall incorporate 2 LED’s.

Firex 21007624 AC Wire-in Combination Carbon Monoxide & Photoelectric Smoke Alarm with Battery Back-up

The Firex Front-Loading Smoke and Carbon Monoxide alarm by Kidde (part # 21007624) offers protection from two hazards – fire and CO – in one unit. This AC-wire with battery backup alarm emits a beeping tone followed by a voice warning that clearly announces the danger by saying, “Fire! Fire!” or “Warning! Carbon Monoxide!”. The uniquely designed frontloading battery compartment makes battery replacement quick and easy, and ensures proper installation. Manufactured with photoelectric sensors for detecting smoke and fire, this alarm also includes the world’s most accurate CO sensing technology based on claims by major manufacturers.

Consumer benefits

A combination alarm provides a 2 in 1 protection against fire and carbon monoxide. Properly installed and maintained, smoke alarms are one of the best and least expensive ways to provide early warning when a fire begins. Smoke alarms save lives, prevent injuries and minimize property damage by alerting residents to a fire hazard.

Sensor Technology

This alarm uses a photoelectric sensing technology that detects visible particles associated with smoldering fires sooner than ionization alarms. Ionization alarms detect invisible fire particles associated with flaming fires sooner than photoelectric alarms. Kidde recommends that both types of alarms be installed inside the home to protect against both types of fires.

Smoke Alarm Tips

Install smoke alarms on every floor of your home, in hallways, inside bedrooms and outside of sleeping areas. On average, families have less than three minutes from the time the first smoke alarm sounds to escape a fire. The sooner you hear an alarm, the more time you will have to get out.

What’s in the box

One single Firex 21007624 AC Wire-in Combination.
