ONELINK® Alarm FAQs
How do the First Alert® ONELINK® smoke alarms link with each other?
The First Alert® ONELINK® wireless integrated smoke alarm system automatically links through the software using 65,000 security code combinations. This eliminates manual dip switch programming saving confusion and time when installing. With First Alert® ONELINK® there is an extremely small chance of a duplicate code being programmed in an adjacent home, ensuring that your wireless integrated smoke alarm system should not receive interference from another system nearby.
