Understanding the Differences Between Smoke Detectors

A smoke detector is an essential fire safety device for every home in Fremont Street, NV. Like most other items, your home’s smoke alarm does not have in infinite lifespan and should be replaced approximately every 8 – 10 years. When it’s time to purchase a new device, it’s important to understand key differences so that you select the best model for your home.

Smoke detectors can sense smoke using two distinct methods. Because of design variations, each system also responds best to different forms of fire.

1. Photoelectric Devices

A photoelectric device uses light beams. When smoke reaches the detector, it scatters light. The disturbed light hits the unit’s sensor, triggering the alarm.

Not all fires burn in the same manner. Because of its design, a photoelectric detector works best in smoldering fires that produce a significant amount of noxious smoke, such as electrical fires.

2. Ionization Detector

Ionization is another detection method utilized in some smoke alarm models. Instead of light, this method uses ions, or electrically charged particles. Ionization models are well suited for fast-flaming fires sparked by ignited wood, paper or flammable liquids.

3. Dual-Sensor

Every home is potentially susceptible to both smoldering and fast-flame fires. To help ensure your family’s safety, you may want to consider purchasing an efficient dual-sensor device that contains both detection methods.

4. Units That Detect Both Smoke and Carbon Monoxide

Carbon monoxide is a deadly, odorless gas that may seep into your home because of faulty appliances or gas leaks. If your home uses a gas stove, furnace or water heater, you should own a carbon monoxide detector. Some smoke detectors also contain carbon monoxide detection technology, making them an ideal choice for gas-energized homes.

Because of their ability to efficiently detect multiple types of fires, fire safety professionals often recommend dual-sensor smoke alarm models. However, every functioning detector is a potentially life-saving tool. Although it cannot eliminate the risk of your home sustaining extensive fire damage, a functioning detector can provide peace of mind that your family will be promptly alerted of danger in the event of a fire.
