How Do Smoke Detectors Work?

Tuesday, March 15th, 2016

A smoke detector is one of those things you hope you’ll never need, but that you’ll be thankful for if you ever do! But how do these devices work? It’s first important to realize that there are two different types of smoke detectors. There is the ionization detector, which houses an ionization chamber with two plates and a source of ionization radiation. The other type of smoke detector is a photoelectric detector, commonly referred to as an optical detector. These aim a light into a sensing chamber at an angle away from the sensor.


Ionization smoke detectors house a small amount of radioactive material between two electrically charged plates, which ionize the air and causes current to flow between the plates. The smoke detector’s battery sends a voltage to the plates, charging one positive and the other negative. If smoke enters the detector, then it disrupts the flow of ions. Therefore, the flow of current is reduced and the alarm is activated. This type of smoke detector is generally more responsive to flaming fires.


Have you ever walked into a store to hear a bell go off, but don’t see a bell? The store likely has a photo beam detector, or a light. When you cross this beam of light, you block it. The photodetector senses the lack of light and triggers a bell. This is essentially how a photoelectric smoke detector works, except that the light and sensor are positioned at 90-degree angles to one another, so that it won’t take an excessive amount of smoke for the alarm to go off. This type of smoke detector is generally more responsive to fires that begin with a long period of smoldering, called a smoldering fire.

Dual sensor detectors are recommended, as they include both ionization and photoelectric sensors. These are most capable of adequately alerting homeowners of either a smoldering fire or a fire with active flames. In an emergency, you need to be able to rely on your smoke detector. Remember to keep your detector well maintained, and replace the batteries as needed, should the detector you choose rely on batteries alone.

Why Hire a Professional to Install a Smoke Detector?

Friday, February 27th, 2015

When you are at home, whether awake and in a productive mood or fast asleep in bed, you should feel safe. While modern appliances, heaters, and electrical systems are all safer than ever before these days, the fact remains that there is always a chance of something going wrong in your home. Whether due to outside forces, a knocked over candle, or any other potential catalyst, there is simply no way in which you can ever rule out the possibility of a fire breaking out in your home. What you can, do, is hire a professional install a smoke detector in your Fall City home. When you do so, make sure that you dial our number. The electricians here at G&S Heating, Cooling & Electrical, Inc. will ensure that the job is done right every step of the way.

One of the main reasons to schedule your smoke detector installation with a trained professional is to ensure that your smoke detector is optimally placed in your home. Needless to say, and for obvious reasons, you want your smoke detector to sound the alarm as soon as possible, should a fire start in your home. This will not be the case, though, if your smoke detector is not optimally situated. In a situation where every second truly does count, you don’t want to leave anything to chance. Additionally, your electrician can determine if multiple smoke detectors are required throughout your home. By having a professional assess your living space, make recommendations, and install your smoke detector properly, you are taking the first steps towards living with the peace of mind that you deserve.

Another reason as to why a trained professional should handle your smoke detector installation is the fact that you really ought to be using a smoke detector that hard wires directly into your electrical system. Yes, your devices should have batteries in them. However, this is as a back up should anything go haywire with your electrical system. If you are relying solely on batteries to keep your smoke detector up and running, you are allowing for a level of human error that you simply cannot afford in your home. Contact us to have your smoke detector professionally installed by a professional you can trust.

We never want to thing about situations such as the possibility of a fire breaking out in our homes. However, preparation for just such events is absolutely necessary.

How Does a Smoke Detector Work?

Tuesday, July 30th, 2013

Smoke detectors are really a marvel of engineering. Not only are they incredibly effective, they are also cheap to make and save thousands of lives every single year. So how do they work? Here at G&S Heating, Cooling and Electrical, Inc. we wanted to put together a quick explanation of how smoke detectors work. Give us a call if you’re having any issues with your home and you need Lynnwood, WA electrical services.

Smoke Detectors: The Basics

There are a couple different types of smoke detectors: photoelectric and ionization detectors though some models of detectors actually use both. The basic idea behind smoke detectors is that they constantly run some kind of continuous process that, if it gets interrupted by smoke, cause the alarm to trigger.

Photoelectric Detectors

These types of detectors use a beam of light emitted from an LED to detect the presence of smoke. If smoke enters the detector it will scatter the beam of light into a sensor which will trigger the alarm.

Ionization Detectors

These types of detectors use a small amount of radioactive material to generate an electric current. In the presence of smoke, this electric current is interrupted which triggers the horn on the detector.

So Which One Is Better?

Trying to compare the effectiveness of each detector is like comparing apples and oranges. Each detector works differently and so they respond differently to various type of fires. Both have undergone rigorous testing in order to receive UL certification. Photoelectric detectors tend to respond faster to smoldering fires because of the large amounts of smoke. But ionization detectors respond faster to flaming fires that have less combustion material in the air; this is why some homeowners disable them during cooking because they respond so quickly to the small amounts of smoke in the air.

If you have any questions about where to install your home’s smoke detectors or if you need any other Lynnwood, WA electrical services just give us a call here at G&S Heating, Cooling and Electrical, Inc.
