Customer Questions & Answers
-
Question:
What is the advantage of hardwired smoke detectors like the First Alert Smoke Alarm?
Answer: Hardwired smoke detectors, such as the First Alert Smoke Alarm, provide continuous power without the need for frequent battery replacements. They are connected directly to your home’s electrical system. This ensures reliable functioning and reduces the risk of malfunctions due to dead batteries. In scenarios where smoke and fire pose immediate danger, having a hardwired system gives peace of mind and increases safety, especially in larger homes. -
Question:
Can the First Alert SMI105-AC smoke alarm be interconnected with other alarms?
Answer: Yes, the First Alert SMI105-AC smoke alarm features interconnectivity, allowing it to communicate with other compatible alarms in your home. When one alarm detects smoke or fire, all interconnected alarms will sound off, ensuring that everyone in the household is alerted quickly. This is particularly useful in multi-level homes or large spaces where an alarm in one area may not be heard by those in another. -
Question:
How does the 10-year battery backup work?
Answer: The 10-year battery backup in the First Alert Smoke Alarm means that in the event of a power outage, the alarm will still function. This battery ensures that your home remains protected, even when there’s no electricity. It’s beneficial during natural disasters like storms where power failures are common, providing uninterrupted protection and allowing for peace of mind that you and your loved ones are secure. -
Question:
What locations in my home should I install smoke alarms?
Answer: It's recommended to install smoke alarms in every bedroom, outside each sleeping area, and on every level of your home, including the basement. By strategically placing the First Alert Smoke Alarms in these locations, you enhance your safety measures. For instance, if your family sleeps on the upper floors, having alarms nearby ensures that any smoke detection during the night will be heard promptly, alerting everyone at once. -
Question:
Can this smoke alarm detect carbon monoxide?
Answer: The First Alert SMI105-AC is designed specifically for smoke detection and does not detect carbon monoxide. For comprehensive safety, it is advised to install a dedicated carbon monoxide detector in conjunction with smoke alarms. Having both types of detectors ensures you are protected against both fire and carbon monoxide risks, which can be life-threatening. -
Question:
What maintenance is required for the First Alert Smoke Alarm?
Answer: Routine maintenance for the First Alert Smoke Alarm includes testing the alarm monthly by pressing the test button and cleaning it regularly. Dust or debris can affect its performance, so a gentle vacuuming or wiping with a damp cloth helps keep it functional. This practice ensures that the alarm is operating correctly and will alert you in the event of a fire. -
Question:
Is the First Alert smoke detector suitable for commercial use?
Answer: While the First Alert Smoke Alarm is primarily designed for residential applications, it’s suitable for small commercial spaces under certain conditions. If you have a small office or retail business, it can be beneficial as part of a broader safety strategy. However, for larger commercial establishments, more robust systems with advanced features may be necessary to comply with safety regulations. -
Question:
What sound does the alarm make when it detects smoke?
Answer: The First Alert Smoke Alarm emits a loud, distinctive beeping sound when it detects smoke. This alert is designed to be attention-grabbing to ensure prompt action is taken. In scenarios like cooking smoke or a more serious fire, the loud alarm will signal to everyone in the household or vicinity, prompting immediate evacuation if necessary. -
Question:
How can I reset the smoke alarm after it's been triggered?
Answer: To reset the First Alert Smoke Alarm after it has been triggered, first ensure that the source of smoke has cleared. Then, press and hold the test/silence button for a few seconds until the alarm stops. This is important to prevent false alarms and maintain optimal function. It's a simple step, but essential to ensure the smoke detector is ready for any future emergencies. -

First Alert Smoke Detectors & Fire Alarms 1046851 Editorial Review
The First Alert Smoke Alarm, specifically the SMI105-AC model, has received positive feedback from customers praising its functionality, ease of installation, and value as a six-pack offering. Users report that these smoke alarms perform effectively and seamlessly interconnect as designed, ensuring that when one alarm activates, all will sound. This feature adds an essential layer of safety, making it ideal for comprehensive home protection. Installation is particularly highlighted as a strong point, with many customers noting that replacing old units was straightforward, often requiring minimal tools and time. For those using older First Alert models, the swap is simple, requiring no additional hardware or complex setup processes. Some users even utilized adapter plugs to incorporate these alarms with different brands, further demonstrating the product's versatility. Additionally, the 10-year battery backup is a significant advantage, as it alleviates the need for frequent battery changes, an aspect that many homeowners find appealing. Nevertheless, a few customers have indicated experiences with alarms starting to fail around the nine-year mark, suggesting that while reliability is generally high, there may be some inConsistency as the products approach the end of their labeled lifespan. Overall, the First Alert Smoke Alarms garner a favorable reception with commendation for their practicality, ease of installation, and long battery life, making them a solid investment for home safety. **
