Special Features

Provides Protection from Fire and Carbon Monoxide in One Unit with Photoelectric Sensor

This unit combines the protection of fire and carbon monoxide alarms in one device, ensuring comprehensive safety.

Fire Warning

• The alarm will continue to sound in the same pattern until the unit is reset or the smoke is eliminated.

Carbon Monoxide Warning

• For carbon monoxide detection, you'll hear four short beeps followed by the verbal warning: "Warning, Carbon monoxide."
• This will continue until the unit is reset or the carbon monoxide is eliminated.

Low Battery Warning

• When the battery is low, you'll hear a single chirp followed by the warning: "Low battery."
• The red LED will flash, and this pattern will continue every minute for the first hour.
• After that, the red LED will flash once every minute and accompany the chirp sound. The "low battery" warning will sound only once every fifteen minutes.

Voice Hush Indication

• When the "Hush" button is activated, you'll hear the voice announcement: "Hush activated."
• Pressing the "Hush" button will also produce the voice announcement: "Hush cancelled."

Alarm Memory

• The green LED will blink once every 16 seconds to alert you if the unit has alarmed for smoke or detected a concentration of carbon monoxide (CO).
• If the alarm has detected a CO level of 100 ppm or greater, pressing the test/reset button will announce, "CO previously detected."
• If abnormal smoke levels have been detected since the last test, the alarm will produce three rapid beeps.

Power and Battery Backup

• This AC-wire unit comes with a battery backup. An included 9V battery ensures protection during short-term power outages.
• The front-loading battery has a unique battery door design for easy access and replacement.

With these features, this unit offers reliable and comprehensive safety for your home.
