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 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.
AC-Wire with battery backup-Powered by home’s electricity in order to provide continuous protection. An included 9V battery protects during short-term power outages.
Front-Loading Battery-Speeds up replacement by eliminating the need to remove the unit from the ceiling or wall.
Unique Battery Door Design-Will not close if battery is not installed properly.
Voice Warning-Supplements warning from the traditional 85-decibel alarm by clearly stating the danger present, fire or carbon monoxide.
Photoelectric smoke sensor-May detect visible fire particles associated with slow smoldering fires sooner than an ionization sensor.
Electrochemical CO sensor-Provides accurate and continual CO protection during the product’s life, remains stable during temperature and humidity changes and resists reactions to household gases that may cause false readings or reduce sensitivity.
Smart Touch Button-One button performs the following functions:
Activates the Hush® feature to temporarily silence nuisance alarms (will announce “Hush mode activated,” or “Hush mode cancelled.”)
Simultaneously tests the unit’s electronics and verifies proper operation
Activates the peak level memory feature (will announce “CO previously detected” if unit has detected levels of 100 ppm or higher)
Resets the unit during a CO alarm (Unit will re-enter alarm within 6 minutes of reset if 70ppm or more of CO is present).
Silences a low battery chirp for up to 12 hours
Silences the end of life chirp for two days Announces “CARBON MONOXIDE PREVIOUSLY DETECTED” if alarm has detected a CO level of 100ppm or higher since it was last reset.
Tamper Resistant-Silences nuisance alarms for approximately 9 minutes. (Smoke must be present before HushTM is activated)
Green LED-Will flash every 30 seconds to indicate proper operation.
Red LED– Flashes in conjunction with the alarm sounding.
End of Life Signal-Ten years after initial power, the unit will “chirp” twice every 30 seconds to indicate the need to immediately replace the alarm.
Low Battery Signal-Will chirp every minute and red LED will flash to indicate low battery condition.
Inter connectable-Will interconnect with up to 24 other devices (18 of which can be initiating) including smoke, CO and heat alarms.
