• Provides protection from fire and carbon monoxide in one unit with Photoelectric sensor..
• Fire warning - 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 pattern until unit is reset or smoke is eliminated..
• Carbon monoxide warning - 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 warning - 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 accompanied by the chirp sound. The “low battery” warning will only sound once every fifteen minutes. Voice Hush Indication: “Hush activated” and “Hush cancelled” voice announcement.
• Alarm memory - The green LED will blink once every 16 seconds to alert a user when the unit has alarmed for smoke or has detected a concentration of CO. If the alarm has detected a CO level of 100ppm or greater, when the test/reset button is pressed the unit will announce “CO previously detected”. If the alarm has detected abnormal levels of smoke since its last test, it will produce three rapid beeps..
• AC-Wire with battery backup, An included 9V battery protects during short-term power outages.
• Front-loading battery with unique battery door design.
• Voice warning with green and red LEDs.
• Photoelectric smoke sensor – May detect visible fire particles associated with slow smoldering fires sooner than an ionization sensor..
• Tamper resistant.

Product Description ------------------- The Kidde Front-Loading Smoke and Carbon Monoxide alarm (part 21007624) offers protection from two hazards – fire and CO – in one unit. Sold under the FireX brand, 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 cls by major manufacturers. Architectural and Engineering Specifications - The combination smoke and carbon monoxide alarm shall be Kidde Unit Number KN-COPE-I (part number 900-0213) or approved equal. It shall be powered by 120VAC, 60Hz source with a 9V battery backup. 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% relative humidity. The unit shall incorporate a photoelectric smoke sensor with nominal sensitivity of 2.05%/ft. The CO sensor shall be of a fuel cell design and shall meet the sensitivity requirements of Underwriters Laboratories UL2034 Single and Multiple Station Carbon Monoxide Detectors. The unit shall qualify for UL-approved wording on the package: “World’s Most Accurate Carbon Monoxide Alarm”. 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 can be installed on any standard single gang electrical box, up to a 4”octagon junction box. The electrical connection (to the alarm) shall be made with a plug-in connector. 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, and a pause. In between, the unit will announce “Fire Fire” The unit shall incorporate 2 LED’s. A green LED will be steady on when AC power is present, flash every 30 seconds when in the battery only mode, every 16 seconds to indicate alarm memory, and every 2 seconds to indicate the Hush“mode is active. A red LED will flash in unison with the sounder pattern. The unit shall include the Smart Hush feature that silences the unit for approximately 8 minutes if a nuisance alarm condition occurs. The Green LED on the alarm will flash every 2 seconds while in Smart Hush and will automatically reset itself. It also provides voice annunciation of “Hush Activated” when Smart Hush is activated and “Hush Cancelled” when the Hush cycle ends. 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” 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. Cl approved by UL, based on manufacturer’s reported testing. .com ---- Kidde Photoelectric Combo Alarm view larger ( https://images-na.ssl-images-.com/images/G/01/th/us/kidde/B003A6249Q_left_large._V360651217_.jpg ) Alarm placements view larger ( https://images-na.ssl-images-.com/images/G/01/th/us/kidde/B003A6249Q_right_large._V360651216_.jpg ) 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 cls 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 ing 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.
