Enhance your home’s safety and enjoy greater peace of mind with the First Alert SCO403 Smoke and Carbon Monoxide Detector Combo Pack. This combo pack bundles together a smoke alarm and a CO detector, offering protection against carbon monoxide and fast-flaming fires at an affordable price.

  • Ionization Sensor Detects Smoke from Flaming Fires

The First Alert SCO403 Smoke and Carbon Monoxide Detector Combo Pack features ionization smoke-sensing technology with a contemporary enhanced smoke-gathering design. Ionization sensors offer optimal smoke detection from flaming fires. The 85-decibel alarm is designed to be loud enough to wake even the soundest sleepers.

  • Simple and Easy to Use

The smoke detector utilizes a single button for simple operation. Press the button on the face of the fire alarm to silence false alarms from cooking smoke or shower steam, as well as to test the alarm to ensure it is working. A blinking power light informs you the smoke alarm is operational, while a low battery-alert lets you know when it is time to change the battery. The First Alert Carbon Monoxide Alarm is easy to set up. Simply insert the battery, and the CO detector will start to monitor your space for carbon monoxide. There are no complicated displays or settings to navigate–a single button silences the alarm and tests the CO detector. A pull-down action chart instructs you of what to do if the CO alarm goes off.

  • Tamper-Resistant Battery Operation

Two 9-volt batteries power the First Alert SCO403 Smoke and Carbon Monoxide Detector Combo Pack, and there is a side-load battery drawer that slides open for easy battery replacement. The smoke alarm features an optional pin to lock the battery and unit in place for tamper resistance, making it so neither the battery nor the unit can be removed without the proper tools. This smoke detector can be easily installed on the wall or ceiling, and it is suitable for use in mobile homes and RVs.

  • The Most Accurate CO Sensor Available

The First Alert Carbon Monoxide Alarm uses an advanced electrochemical CO sensor to detect elevated carbon monoxide levels. When CO is detected, the carbon monoxide detector sounds an alarm to warn you of the threat.

  • Comprehensive Warning Features

When carbon monoxide levels rise, the carbon monoxide detector sounds an 85-decibel siren that is designed to wake even the soundest of sleepers. A low-battery light and alarm alert you when battery power is running low, and an end-of-life timer lets you know when the device should be replaced. Each CO detector lasts approximately five years.
