The Top Five Smoke Alarms on the Market Today


The importance of a smoke alarm in home safety cannot be overstated. By definition, a smoke alarm is a device that has the ability to detect fire and produce an alarm as a result. Smoke alarms are small and usually fitted on the ceiling. They can detect fires early enough to give you those precious minutes you need to leave the house safely. As such, they can go a long way towards ensuring the safety of you and your family in case of a fire outbreak. Unfortunately, with the numerous types of smoke alarms in the market today, it can be a bit challenging to pin down to the most suitable device. Modern smoke alarms can be grouped into four main categories – optical, ionization, heat and combined.


These smoke alarms are more expensive and ultimately more effective. They can detect larger smoke particles produced during fire incidents but are less sensitive to fires with fast flames. These alarms are installed near kitchens (not in) due to their ability to go off with the slightest provocation, like when a toast is burned.


These smoke alarms are very cheap. They are extremely sensitive to small smoke particles produced by fast flaming fires from burning wood or paper. The alarm detects this kind of fire even before the smoke gets thick. Ionization smoke alarms are less sensitive to smoldering and slow burning fires that give off large smoke quantities before flaming occurs. They are extremely sensitive to be installed in kitchens.

Heat alarms

these alarms are insensitive to smoke but can detect a temperature increase caused by fire. They can be installed in a kitchen. They tend to cover a small space in a room, so a larger kitchen will potentially need several heat alarms. Combined heat and optical smoke alarms – this smoke alarm has a higher rate of detection and is ideal for reducing cases of false alarms.

Smoke alarms can be powered by electricity, a battery or both. Some are interlinked so if any smoke is detected in a room, the rest can raise the alarm as well. Here are the top 5 smoke alarms on the market today.

First Alert Dual Sensor Smoke and Fire Alarm (battery-powered) SA320CN


Although smoke alarms are designed to detect smoke, various sensing technologies react differently to certain fires. This alarm uses both photoelectric and ionization sensors to give the user the earliest warning possible – regardless of the cause of fire. In some cases, the fire may smolder for hours before it erupts into flames. The photoelectric sensing technology is more efficient at detecting smoldering fires than the ionization sensing technology. However, the latter is more productive at detecting fires that erupt rapidly into flames. Apart from utilizing photoelectric and ionization smoke sensors, this alarm operates on 2 AA batteries. It also emits an 85Db loud alarm to give ample warning. Its super sensing technology enables it to reduce nuisance and non-emergency alarms.
