Alarmingly, nearly ten people die every day as a result of home fires in the US. In Europe, twelve people die every day according to Information Bulletin of the World Fire Statistics Centre – Geneva Association as well as https://www.europeanfiresafetyalliance.org/our-focus/statistics/.

And on average  35 people die everyday in Russia due to related fire incidences. The most affected groups of people in most cases are the children and the elderly.

However, on the bright side of things, most of the residential fire related deaths are totally preventable.

Why have Wireless Interconnected Smoke Alarms with 10 Year Battery?

kidde battery powered wireless smoke detectors

Homes with a working smoke detector reduced significantly the chances of fire fatalities.  Nevertheless, homes with INTERCONNECTED smoke detection system enhance the chances for survival tremendously.

The primary purpose of a smoke detector is to warn you of potential fire danger hence providing you with some lead time to escape.

Assuming you are asleep on the first floor of your home. Meanwhile, fire starts in the basement or in your kitchen which is on the ground floor. If you do not have interconnected alarms, the basement (or wherever the smoke or fire starts) smoke detector will go off.

However, you may not hear it because you are on the first floor or worse still, sound asleep. The smoke or fire may have to build up to trigger the next nearest smoke detector. With this in mind it may be too late as there may be insufficient time to find a path of escape!

In case of interconnected smoke detectors, when the basement smoke detector goes off, all the alarms in the house go off (including the smoke alarm in your bedroom). This helps because you have enough time to escape and evacuate before exit paths are too dangerous.

Depending on the State that you live, some insurance companies may not compensate you if they found that your smoke alarms are not interconnected. This should worry you unless you are a risk taker!

Assuming an average wireless smoke detector costs 50 dollars and you have 6 locations to install. That will be a total of 300 dollars. Keep in mind that the next replacement is due in 10 years! It translates to 30 dollars (only) each year, just to keep you safe using some of the best hassle free to install smoke detectors.

How to Set Up a Wireless Fire Alarm System

Traditional network was achieved by hard wiring the smoke alarm detectors. However there is modern technology that makes linkage of smoke detectors more convenient. A good example is the Kidde wireless interconnected smoke detectors.

General Steps of Installation

Let’s assume you have five of these detectors. The following steps will give you some pointers:

  1. Put the batteries to power them.
  1. Test each one of them for proper functionality.
  1. Program (for smoke detectors with voice) one at a time according to location of use and label them accordingly. (The label will help you avoid mix up just in case you forget)
  1. Most wire less smoke detectors will require that you pair them together so that they can transmit and receive signals to and from each other. For example, you press the button of 1 and 2 at the same time, then 1 and 3, then 1 and 4 and finally 1 and 5 to make 1 recognize all the other 4.
  1. Similarly you have to do that for no. 2 with all the others, then no. 3 with all the others.

You do not need an electrician to install interconnected wireless smoke detectors. You can do it yourself 🙂

  1. . Finally, after installing the smoke alarms in their respective locations, REMEMBER to all of them again. When you press the test button of the smoke alarm in the kitchen, all smoke detectors should go off and alert you of the smoke/fire in the kitchen.

Please note that if you are using dual smoke and carbon monoxide detectors, they will differentiate the danger and warn you accordingly. The voice will inform you whether it is smoke/fire or carbon monoxide and of course the location.

Various visual signals are also included e.g. flashing LEDs as well.

We recommend you go through your manual carefully so that you can install the new smoke detectors spot on.

How Wireless Interconnected Smoke Detectors Work

Wireless smoke alarm products such as first alert smoke detectors employ the use of a very reliable means of communication; the mesh networking.

wireless interconnected smoke detectors
A mesh network of 5 smoke detectors

Mesh networks have all the smoke detectors included in the network distributing data to each other.

The message is transferred along the shortest path and if the path is broken, the mesh network is configured to find another available path to the destination.

This ideally creates a very reliable set of fire detection system and this explicitly explains why mesh network was first developed for military use. As shown above, it is failure proof!

The hard wired smoke detectors communicate by sending a 9V signal to the other devices and you can guess what will happen if the wire is broken; No contact! No warning to vacate in case of an emergency.

Wireless Smoke Detectors that Communicate with each other

You have no need to worry about interference from other wireless devices or signal as the products are fully compliant to international standards.

The radio frequency commonly used is 433 MHz that does not attenuate or weaken through walls or floors or other ordinary building material. This frequency spectrum has less traffic and hence less interference.

There is great flexibility as to the number of smoke detectors that can be used in the network with some manufacturers designing for up to 12 smoke detectors and six other additional detectors which could be carbon monoxide detectors, heat detectors or other types of sensors.
