Smoke detector maintenance for fire preparedness


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 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, like the First Alert Onelink Safe & Sound smoke alarm, you’ll receive mobile notifications via First Alert’s Onelink 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.
