First Alert 1039718 Carbon Monoxide Alarm 9V

Product Description

The FIRST ALERT 1039718 is a battery-operated carbon monoxide alarm designed for residential use. It uses an electrochemical CO sensor to detect carbon monoxide gas that cannot be seen, smelled, or tasted. The unit runs on a single 9-volt replaceable battery, making it functional during power outages without any hardwired connection or outlet. The internal sensor carries a service life of up to five years. An 85-decibel horn activates when CO levels reach dangerous thresholds. A pull-down action chart printed on the unit provides occupants with immediate guidance if an alarm triggers. A test/silence button allows functional testing and alarm silencing. The unit is UL listed.

This alarm is suited for residential installations in locations where a reliable, self-contained CO detection device is needed without permanent wiring. Because no outlet or electrical connection is required, placement is flexible. An optional wall mount bracket is included for fixed mounting. It is appropriate for bedrooms, hallways, and common areas per NFPA 720 and local code requirements. Licensed contractors, property managers, and knowledgeable installers place this unit in single-family homes, apartments, and similar occupied spaces.
