First Alert CODIG Dual Power Carbon Monoxide Plug-In Alarm with Battery Backup and Digital Display (Model CO615) uses an electrochemical carbon monoxide sensor-the most accurate technology . Installation is as simple as plugging it in to any wall outlet. Its easy-to-read backlit digital LED display gives you a clear read-out of current CO concentrations in parts per million. The alarm includes a battery back-up giving you peace of mind in a power outage. Multi-function backlit digital display allows you to easily see the CO level and battery power level at a glance. Unit displays and captures peak CO level reached in the event of an incident. The test/silence button both silences a non-threatening alarm or low battery warning and allows you to test the unit's functionality. The unit monitors and re-alarms if carbon monoxide levels persist sounding a loud 85-decibel horn. An audible and visual low battery signal alerts you to replace the battery and an indicator alerts you when a battery has been removed. An end-of-life alarm of three chirps alerts you to replace the unit.
