FAQ's and Troubleshooting


How do the First Alert® OneLink® alarms link with each other?

DipswitchThe linking is automatic through the software with 65,000 security code combinations. This eliminates manual dip switch programming as on the competitive product with only 255 combinations. This saves confusion, time and money on installation. With First Alert® OneLink® there is an extremely small chance of a duplicate code programmed in an adjacent apartment’s units as with the competition. No trying to remember dip switch locations for each apartment’s units. Easier programming means a more cost effective installation.
