Since there are a lot of smoke detectors to choose from, it can be difficult to pick the best one. After seeing our top picks, you might be wondering what to look for in a smoke alarm, but the choice ultimately depends on your personal preferences and the features that are important for your daily life and safety. It is crucial to be informed before purchasing a smoke detector, so we’ve put together this guide to help you.
Three types of smoke alarms are photoelectric, ionization, and dual-sensor detectors that rely on the previous two.
Using an ionization smoke detector is best for finding small particles that smoke coming from flaming fires usually has. Smoldering fires make smoke that has larger particles, so an ionization alarm might not be good at detecting them. These devices also contain Americium-241, which is a radioactive material located between two plates that are electrically charged. The material will ionize the air around it to create a current between these two plates. Smoke disrupts the current in the device and activates the alarm. However, they can be easily triggered with a small smoke coming from burnt food or even steam from showers, and therefore you are at risk of getting false alarms if you place them near a kitchen or a bathroom.
When it comes to photoelectric smoke alarms, a light source is pointed to the sensing chamber at a specific angle and when the smoke is present, it will trigger the alarm. This type of detector is best for fires that will make a lot of smoke but without visible flames. Even though this type of device is not prone to false alarms, they can still randomly set off if there is a buildup of dust in the detector.
The dual sensor detectors are a combination of the previous two – ionization and photoelectric sensors. Some models need both sensors to properly trigger the alarm before the fire, which will minimize the risk of false alarms but possibly delay it too, while others only need one of them to sound the alarm, which is a bigger risk false alarms.
These devices can rely on batteries or be hardwired into the electrical system of your home and have batteries as a backup for power outages. The recommended option is hardwired alarms that will be placed on your ceilings or walls, and then automatically connected with other smoke devices of your house. Since they can be interconnected with other devices, installation will require a professional which can be costly. Battery-only smoke devices are cheaper and more convenient for installation – you can even install them yourself. The batteries are either AA or Lithium rechargeable that need to be changed once in a while. Models that use lithium batteries will last longer, but regardless of the battery type, they still need to be replaced once or twice a year if they’re not used.
We’ve already discussed that some smoke or carbon monoxide (CO) detectors can be linked together or to other units in your house. Connecting the devices means that all of them will go off if one of them is triggered, which is useful, adds to your security, and informs you of any fire danger even.
These devices will connect to your wireless network, and you will be notified on your smartphone if the battery is low and if the device is switched off or on. Apart from that, it will also inform you when there is a fire, even if you’re away from the house. It is compatible with different smartphones and with any voice assistants and smart hubs.
Many models have a silent button that will silence an alarm instead of having to disable the entire unit, which will minimize the chances of forgetting the batteries. However, you need to keep in mind that this button is only a temporary measure, and the alarm will sound again if triggered.
Every smoke detector should have at least one LED light that will show updates. This feature is essential for hearing-impaired individuals. Some alarms also have a safety light that will illuminate the room in the dark.
Some smoke alarms can also function as carbon monoxide (CO) detectors. The device will have a digital display of the CO levels at all times, so you can check them anytime you want. Some models can also show the peak CO level that happened since the last reset, letting you know about any spikes that might have happened while you were sleeping or away.
Certifications are an essential aspect to consider when getting a smoke alarm. If a device has a certification, it means that experts guarantee that it will protect you. One of them is Underwriters Laboratories Standard (UL) that will indicate that the smoke detector passed the worldwide recognized safety standards.
Some smoke detectors have voice alerts that will inform you verbally about the danger. Instead of using texts or smartphone notifications, the device will use a voice alert to tell you where in your home the fire incident has occurred.
Smoke devices should be installed on the walls or ceilings in every part of your house, including the basement and attic. They should also be put slightly apart from clutter and dust, to avoid false alarms. Place ionization devices at least ten feet away from the appliances that can trigger them, like showers and kitchen appliances.
Smoke detectors, like other appliances, have their advantages and disadvantages. The main advantage is safety. They protect you from any fire hazards, and in some cases, from carbon-monoxide as well. These products will notify you if there is smoke or a small fire in your home so that you can evacuate faster and call for an emergency. Additionally, most models are hardwired, which means that they power from electricity and use batteries as a backup in case of power outages.
On the other hand, these devices can have higher prices, and some require professional installation that will cost you even more. Additionally, if the standardized smoke detector is out of warranty, it can cost a lot to repair. Also, non-fire related things can trigger these devices and cause them to give false alarms, which can be very frustrating and annoying.
