A fire alarm system is number of devices working together to detect and warn people through visual and audio appliances when smoke, fire, carbon monoxide or otheremergencies are present. These alarms may be activated from smoke detectors, and heat detectors. They may also be activated via Manual fire alarm activation devices such as manual call points or pull stations.
This alarm includes a voice warning system that makes four announcements: fire, carbon monoxide, low battery, or smart hush 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 unit uses three AA batteries, protecting you and your family even during a power outage. This alarm uses ionization-sensing technology for the smoke alarm. Ionization-sensing alarms may detect invisible fire particles (associated with flaming fires) sooner than photoelectric alarms. Photoelectric-sensing alarms may detect visible particles (associated with smoldering fires) sooner than ionization alarms. Kidde strongly recommends that both ionization and photoelectric smoke alarms be installed to help ensure maximum detection of the various types of fire that can occur within the home. The battery-operated fire alarm offers easy installation. View larger. Combination Smoke/Carbon Monoxide Alarm The Kidde combination carbon monoxide and smoke alarm includes a voice warning system that eliminates confusion and clearly warns you and your family of a smoke or carbon monoxide (CO) danger, of low battery, or of hush-mode setting. Alarm Warnings Fire: 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 the pattern 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: 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 and will be accompanied by the chirp sound. The low-battery warning will only sound once every 15 minutes. Voice Hush Indication: "Hush activated" and "Hush canceled" voice announcement. Peak Level Memory: If the alarm had detected a CO level of 100ppm or higher when the test/reset button is pressed, the unit will announce, "Carbon monoxide previously detected" to warn of the CO incident.
