The First Alert 9120B Smoke Detector is a reliable and essential device that every home should have for fire safety. This smoke detector has been designed to detect even small traces of smoke, ensuring early warning in case of a fire emergency. In this review, we will discuss the factors a user should consider before purchasing a smoke detector and highlight the key features and benefits of the First Alert 9120B.

Factors to Consider Before Purchasing

1. Sensitivity: One of the crucial factors to consider when buying a smoke detector is its sensitivity to detect smoke. A highly sensitive smoke detector like the First Alert 9120B can detect even small quantities of smoke, allowing you to take immediate action.

2. Power Source: Smoke detectors usually come in two power options - battery-operated and hardwired. Battery-operated detectors are portable and do not require any electrical connection, but the batteries need to be changed regularly. On the other hand, hardwired detectors are directly connected to the electrical system and often come with a battery backup in case of power outages. The First Alert 9120B can be both hardwired and battery-operated, providing flexibility and reliability.

3. Interconnectivity: Interconnectivity allows multiple smoke detectors to communicate with each other, so when one alarm is triggered, all interconnected detectors will sound the alarm. This feature is highly important, especially in larger homes, as it ensures that everyone in the house is alerted to a potential fire. The First Alert 9120B can be interconnected with up to 18 compatible units, making it a suitable choice for homes of any size.

4. Additional Features: Some smoke detectors offer additional features such as carbon monoxide detection or remote monitoring. These additional features can enhance your overall home safety, but they may also increase the price. It is important to consider your specific needs and budget before opting for a smoke detector with extra features.

b. 85-Decibel Alarm: The built-in alarm of the First Alert 9120B emits a loud 85-decibel sound when smoke is detected, ensuring that everyone in the house is alerted to the potential danger. This volume is sufficiently high to wake up even heavy sleepers, providing an added layer of safety.

c. Easy Installation: The First Alert 9120B comes with a universal mounting bracket and easy-to-follow instructions, making the installation process quick and hassle-free. Whether you choose to hardwire or use batteries, the installation is straightforward, requiring no specialized tools or expertise.
