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 claims by major manufacturers. 10-Year Life: “If your CO alarm was manufactured prior to 2013, it does not have a 10 year life. Consult your User Guide for additional details, or contact us for more information.”
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:
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:
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.
