Top 6 Smoke and Carbon Monoxide Detectors


If you are here, then I guess you are looking for the best smoke detectors. Briefly, let’s go through what smoke detectors are and their importance. A fire alarm or a carbon monoxide alarm warns the occupants of a building of fire or imminent fire. What it does is to sense the presence of smoke or heat and notify the residents of a particular place with a warbling or chirping sound. Both commercial buildings and households use heat detectors. The smoke detectors in commercial buildings send an alarm to the fire alarm control panel connected to the building, while the detectors in houses send an audible sound from the carbon monoxide or smoke detector itself.

The two basic types of smoke detectors are ionization and photoelectric. The ionization heat alarm is more sensitive to small flames and responds 30 - 90 seconds. The photoelectric fire alarm, on the other hand, responds more to smouldering or slow-burning fire. Just like every other product on earth, to get a quality smoke detector can be overwhelming since all smoke alarms claim to be the best. Nevertheless, you have nothing to worry about as we’ve compiled a list of the best smoke detectors available. This article will offer you comprehensive information on the best fire sensors with their pros and cons. Experts have tested these detectors, so the quality is guaranteed.

That depends on the number of rooms in your house. Nevertheless, you should install smoke or CO alarms in every room, sleeping room and on every level of the home.

How far should a smoke detector be from the light?

You should place the smoke detector at least 13 inches/300mm far from the light that may cause electric noise and false alarms.

Do smoke detectors also detect carbon monoxide?

No. Smoke detectors do not detect carbon monoxide and vice versa. Regardless, some devices that combine the features of smoke and CO detectors.

Can I disconnect a hardwired smoke detector?

Yes. To disconnect a hardwired smoke or CO detector, get a ladder, place it firmly on the ground and climb it to reach the smoke detector. Then, grasp it in your hand and twist in an anti-clockwise rotation. This action will free the fire detector from the mounting surface or level. Gently pull it away when it’s free.
