Most of the hardwired smoke alarms are connected to a power source that is mostly 120V alternating current. The batteries are provided as back up in case of main power outage. It is worth noting, that there are countless of smoke detectors that are not hard wired smoke detectors – they are only battery operated.
Advantages of hard wired smoke detector vs battery operated
Hard wired smoke detectors have several additional benefits unlike standard battery operated smoke detectors. Their primary source of power is your main electrical connection. Therefore, there is no uncertainty of faulty batteries or times that your smoke detector has no power; you are guaranteed of a functioning smoke detector at 100% of the times. This is very important and a requirement to comply with fire safety regulations.
On the other hand, there has been a great technological breakthrough in the recent past and battery operated smoke alarms can also ensure that your smoke alarm is functional always. They do this by designing an electronic system that monitors the health of the batteries. When the batteries have low level energy to sustain the smoke alarm, a chirping sound is activated that reminds you that you need to change your batteries.
The other advantage of hard wired smoke detectors is the ability to be interconnected with a series of other smoke detectors in the house. Lets assume you have several rooms that you have installed your hard wired smoke detectors. There is an extra cable that allows you to interconnect all your alarms. Why is this helpful? When a fire starts in another room (where you are not physically present) and the smoke detector in that room is activated. You may be unable to hear the alarm sound immediately. But time is of essence when there is fire! The US fire administration in its latest report notes that fire doubles every 30 seconds! The interconnections are done to enable and trigger all alarms. Thus, irrespective of your location, you will definitely hear the alarm sound of the most immediate hard wired smoke alarm near you. It saves a lot of time for escaping because one does not need to wait until fire builds up into your room for the closest alarm to sound.
Again, with current breakthroughs in fire alarm technologies, this hard wired smoke detectors interconnections’ is traditional. It works okay, but there is a lot of wiring involved. You may need to involve a technician to do all that. That will cost you more bucks! It is even more disappointing if you are installing this kind of connections after your home has been built and finished. Since some of the cables may have to be run through your walls, drilling your already decorated and nice looking walls is inevitable.
To solve all these problems, you need wireless smoke detectors for interconnections and linking. They could still be hard wired smoke detectors supported by your 120V AC power with additional battery back up, but you could save yourself from the costs and hustles of running cables just to deal with interconnections.
We introduce you to the best products available among hard wired smoke detectors that will not only maximize your protection from fire related hazards, but also save you money, time and ease of using them.
Combination Hardwired Smoke Carbon Monoxide & Carbon Dioxide Detectors
You can reap multiple benefits from a single smoke detector unit by leveraging on additional features. For example a hard wired smoke detector in combination with a carbon monoxide detector.
You may also consider having both ionization and photoelectric sensing technology all in one detector. Additionally, you may prefer the detector to have programmable location for voice alarm. The prices for hardwired smoke detectors are very friendly compared to wireless smoke detectors. Hard wired smoke detectors may require you plan in advance while you are constructing your home or face the compromise of laying cables later. However, a professional technician should do an excellent installation job.
Ten Years in Review
It was interesting to note from a recent report from the US Fire Administration that fire departments responded to a staggering 1.3 million fire calls in 2015. The statistics slightly improved in 2016 and 2017 as well. The report “Fire in the United States 2006-2015” was released in December 2017. The report covers fire incidences over a period of 10 years.
For fires that occurred within residential buildings, the largest contributing factor was kitchen fires attributed to cooking at 17%. Other careless activities such as children playing with fire and cigarette leftovers in the wrong place followed closely at 14%. It is surprising that cooking was also a leading cause for nonresidential fires. Electricity related fires accounted for 12% of reported incidences.
It is also interesting to note that African-Americans were most affected group of people. Males had a higher likelihood of dying in a fire than females. These data is primarily obtained from The National Fire Incident Reporting System.
The overall trend has been improving
The main reason for improvement has been due to the increased use of smoke detectors. That is a very positive fact. We at Bottom Line of Alarm Technologies are proud of the achievement that have been realized through the use of smoke alarms. The statistics are supportive that employing technology helps to improve and guarantee safety at homes and in offices.
The report also cites the use of sprinklers as another great enabler in combating fire menace in the U.S. fires. Other factors include training and awareness, fire code and standards, enhanced firefighting equipment as well as adopting safe building techniques.
Great attention should be given to prevention, preparedness and response. Among the three, prevention is at the front line. The US Fire Administration acknowledges that prevention is best done through smoke detectors.
