Understanding The Difference in Smoke Detectors

Understanding The Difference in Smoke Detectors

  • Hard-Wired vs. Battery Operated

    Hard-wired smoke alarms connect to your home’s wiring and electric system. They often require professional installation and may not work during power outages. On the contrary, battery operated smoke detectors are easier to install and don’t pose as much of an electric concern. The best bet is to invest in a hard-wired smoke detector with a backup battery for an interconnected smoke detecting system that still works during an outage.

  • Ionization vs. Photoelectric

    Ionization smoke alarms respond quickly to fires that arise quickly from flammable objects and liquids, also known as flaming fires. On the other hand, photoelectric smoke detectors work best after a long period of building smoke of smoldering fires. Consider placing dual sensor detectors throughout the home to detect both photoelectric and ionization using one alarm.

Smoke Alarm Facts & Figures to Consider

Smoke Alarm Facts & Figures to Consider

  • According to the National Fire Protection Association, 25 percent of smoke detector failures stem from dead batteries.
  • Surprisingly, the NFPA reported 63 percent of the most recent smoke alarm detections were due to normal cooking, smoke and steam. Only 5 percent reported the alarm was due to a fire.
  • Smoke detectors reduce fire deaths by half. Yet, in nearly 40 percent of recent home fire deaths, there was not a smoke detector in the home. (FEMA)
  • The Red Cross reported that if all U.S. homes had working smoke alarms, nearly 900 people could be saved from home fire deaths annually. Having both smoke detectors and sprinklers could reduce an individual’s risk of a fire-related death by 82 percent.
Benefits of Smoke Detectors

Benefits of Smoke Detectors

Every smoke detector has one goal – to improve fire and smoke safety. The choices are endless but should be tailored to what works best for your home. You can buy a smoke detector as a standalone device or with a home security system. Remember to always buy from a trusted manufacturer, and read all manuals before installment. For assistance with installing and understanding  the smoke detector requirements contact your local fire department. Regardless of the options, smoke detectors aren’t optional when it comes to home safety. Here are the most common benefits.

  • Faster smoke detection. The sooner the detector finds danger, the better. Extra seconds to safely evacuate the home could save you from inhaling life-threatening smoke and fumes. Remember to have a fire evacuation plan for a fast and safe exit if the alarm sounds.
  • Cost-effective fire safety. Most smoke detectors cost less than $15 and can often be purchased in sets of two or more for better cost savings. Smoke detectors with smart technology can be more costly but come with added benefits such as mobile notifications of smoke, voice commands and easy syncing to other home devices. For just a few bucks, you’ll have peace of mind while preparing your humble abode for the unthinkable.
  • Easy monitoring. Smoke detector check-ups are often quick and easy. It’s as simple as setting a monthly reminder to vacuum the detector free of dust and changing the batteries annually. Even during weather preparedness, most smoke alarms include backup batteries to continue monitoring during power outages. These regular routines keep the home ready for the first sign of trouble.

Our experts have now equipped you with everything you need to know about the importance of smoke detectors. From top recommendations to tools and tips, you’ll be able to pick the perfect smoke detector for your home with ease. Ready to get started? Find the best to get prepared today.

Smoke Detector Maintenance Tips

Smoke Detector Maintenance Tips

  • Always be aware of the expiration date of your smoke alarm. Most smoke detectors should be replaced every 10 years.
  • Set reminders to test and clean smoke detectors monthly to ensure they are clean and working properly. Even if batteries aren’t low, they should be changed annually.
  • FEMA reports most home fire deaths occur during the night hours. As a protective measure, install a smoke alarm in every bedroom and keep it free from windows and air vents.
  • The best placement for smoke detectors is on the ceiling, but if you have to mount them on the wall, make sure it’s within 6-12 inches from the ceiling. Also, avoid placing smoke alarms within 10 feet of kitchen gadgets to avoid false alarms.
Smoke Detector FAQs

Smoke Detector FAQs

What is a voice-enabled smoke detector?

Voice-enabled smoke detectors are growing popular as smart tech evolves. Simply put, think of having Siri or Alexa enabled within the smoke detector to give you voice commands rather than just a siren. Smart smoke detectors use mobile apps or built-in control panels for ease and convenience. In the event of an emergency, for some smart smoke detectors you’ll receive mobile notifications via an app.

What is a smart smoke detector?

Smart smoke detectors go beyond the basic uses with more control than through a one-touch button. They often connect to Wi-Fi and mobile devices to quickly manage smoke detector settings such as battery life, resetting or defects. The most popular feature that buyers enjoy is peace of mind away from home. When the smart smoke detector is connected to your smartphone, you’ll receive mobile notifications via the alarm’s app. Most detectors are also seamlessly connected to other smart technology home devices for a smart home that can all be managed from your mobile device.

What are smoke detector programmable locations?

Some smart smoke detectors pinpoint the exact room within the house where smoke or fire is detected. During installation, you’ll have the power to assign each smoke alarm to a preset location or room using a mobile app or control panel. When the alarm detects fire or smoke, the voice command will automatically alert you and your family of the location of the issue for a safe evacuation.
