Best Wireless Smoke Detectors

Smoke and fire detectors save lives hence they are an essential part of your home security system. If you haven’t installed a smoke detector in your house yet or want to add more coverage, having one installed now could be difficult. Most likely you will need some professional assistance to fit them properly to your system and do the proper wiring.  If you want to avoid that, wireless smoke detectors can be a great option. With no wiring hassles, transmit signals through standard radio bandwidth as well as auditory alerts to notify you if there is smoke in the house.

How to Install a Wireless Smoke Detector

The installation of a wireless smoke detector is easier than that of a wired one. A wireless detector is operated by its own battery, so you don’t need to limit it to any one room. It can easily be installed in a few minutes without any wire-connecting or cable-checking.

All you have to do is screw on the mounting bracket where you want it. This is similar to the method for a wired smoke detector. Some detectors may have a wall unit and can then be plugged into any electric outlet you prefer. You can even use wireless alarms to replace hardwired ones or connect to them for upgrading your whole system.

When you buy a wireless smoke detector, you may also get a dipswitch on the backs of these devices. the positions of these dipswitches would determine your system’s ID, which should be unique in order to avoid crossing lines with any nearby wireless systems.

Finally, you would have to install the batteries, and then press the testing button to make sure the alarm is actually working. Be sure to do this at arm’s length, or the alarm sound could damage your ears.

Features to Consider in Wireless Smoke Detectors

A wireless smoke detector’s main purpose is to emit an alarm when it senses any smoke nearby. However, this purpose has to be enhanced by several features. Otherwise, the detector might start emitting an alarm even when there’s no emergency, such as when it detects the smoke from burnt food or even a cigarette.

The smoke detector you purchase should hence preferably have a heat, temperature, and humidity sensor. This would enable it to differentiate between slow fires, fast fires, and just smoke without any fire as well.

Another important feature in a wireless smoke detector is its battery life. Since these devices are solely reliant upon the batteries installed in them, you should be able to expect a long life from them. A lithium ion battery would last for around a decade if it’s of decent quality.

The next feature you should consider is that of carbon monoxide detection. A smoke detector should be able to alert you if the air you’re breathing is getting toxic or poisoned. This could be highly important especially if you live in a city where the air pollution is reaching new levels.
