- Additional features such as a microprocessor that limits nuisance alarms and a single test/silence button add versatility to an already efficient carbon monoxide alarm.
- Includes an advanced electrochemical sensor that detects carbon monoxide leaks from a variety of sources, such as faulty fuel-burning appliances, blocked chimneys, and cars left running in the garage.
- The unit comes with a 9-volt battery and features a pivoting, easy-to-access battery drawer that allows you to replace the battery without dismounting the alarm.
- Can also integrate with up to 12 other First Alert or BRK hardwired alarms for coverage of larger spaces.
- It also integrates with up to six other compatible devices, such as bells, horns, and repeaters.
