The First Alert 9120B Hardwired Smoke Alarm with Battery Backup is a vital addition to any safety-conscious home. With its efficient design, it ensures that residents are alerted promptly in the event of a fire. This alarm operates on a 120-volt power source, seamlessly integrating into the home’s existing electrical system while providing a backup battery that guarantees functionality even during power outages. The device incorporates an ionization smoke sensor, which excels in detecting particles from fast-flaming fires, making it particularly responsive in critical situations.
One of the standout features of the First Alert 9120B is its impressive 85-decibel alarm, which is loud enough to rouse even the soundest sleeper, ensuring that any potential threat is met with an adequate warning. Installation is made simple and hassle-free with its gasket-less mount system, allowing for perfect alignment without the frustrations often associated with complex installation processes. In addition to this, tamper-resistant locking pins secure the unit firmly in place, delivering peace of mind that the alarm remains operational and undisturbed.
This smoke detector stations itself as a user-friendly option with its convenient test and silence button, which enables homeowners to quickly check the alarm's functionality and mute any false alarms. Integration with up to 12 additional First Alert or BRK hardwired alarms is also supported, creating a comprehensive interconnected safety network throughout the home. The device includes a latching indicator which distinguishes which unit has been triggered in the event of an alarm activation, simplifying the process of identifying smoke sources during an emergency.
When compared to other smoke alarms in the market, the First Alert 9120B stands out due to its combination of hardwired capabilities and a reliable battery backup.
