Are Battery-powered Smoke Alarms Legal?

Smoke Alarm Batteries

Recently there are new standards that need to be set regarding battery–powered smoke alarms, whenever there are carbon-fueled appliances, a carbon monoxide detector is needed.

Smoke alarms not only detect smoke and fire but have combination units that detect carbon monoxide, so all homes must follow these standards.

Now it has become a part of legislation in many countries to install smoke alarms in every store, home and sleeping areas like in Ontario (Canada).

The standards that must be considered include one smoke alarm in every possible space that is or might exposed to fire specially in kitchen, all alarms should be fitted in ceiling and interlinked.

Not only are these alarms legal, but also very important after the incident of fire at Grenfell tower in London. To escape from fire in unfortunate events you may have only few seconds to escape so to make detection of fire beforehand, these alarms play a vital role.

Smoke detectors are an essential first line of defense for you and your family. But, install and maintain these devices correctly in order to provide you with sufficient protection.

Hardwired vs. Battery Powered Smoke Alarms

Different smoke detectors may look alike but there are vital features that vary with different models. Some models include a built-in carbon monoxide (CO) detector, which alerts you to deadly levels of this toxic gas according to consumer report.

Hard-wired as the name indicates involves wiring and requires electricity that must be powered by the building in which it is being installed, if there is load shedding or some other issue with electricity these hard-wired smoke alarms must have a backup feature of battery installation.

Hardwired smoke alarms must be replaced with the one of its kind as a battery operated smoke alarm couldn’t be its substitute. Hardwired are more generally considered because they do not solely depend upon electricity. They have a battery backup.

Whereas battery-powered smoke alarms are totally dependent upon batteries and we are not sure about the life of a battery. Hardwired alarms have both the power of electricity and batteries so they do not turn off until they shut off externally while the amount of time Battery Powered Smoke Alarms sound depend upon how much battery is left.

In a solution to this problem there are now lithium batteries with the life efficiency of 10 years so the need to replace battery is now reduced. These are also easy to use than the hard-wired Smoke Alarms which installation needed to be interconnected if there are more than one.

What kind of Batteries Do Smoke Detectors Take?

Mostly smoke detectors have alkaline batteries with the voltage of 9V or AA (cylinder shape). These AA batteries are three times more effective than 9V batteries but need to be replaced after every 6 months while some detectors use lithium batteries that have life span of 10 years.

These are the built in batteries and we don’t have to replace them, it is also known as hassle-free smoke detector in terms of battery.

There are rechargeable batteries but as they degrade with time and sensitivity in smoke detection is reduced so they are not suitable for smoke alarms.

Any alarm that is bought will contain information about its lasting time and date should be checked on which the system must be changed – this can be up to 10 years.

Changing batteries could be difficult and not safe so sealed tamper proof batteries are preferable. This preference is also based on several tragedies happened in past where alarms have not worked because of the expiration date of batteries or might be removed by people.

The National Fire Protection Association (NFPA) approved the suggestion of changing the batteries in smoke alarm after every 6 months. At First, 10-year smoke alarms are offered that have a built-in 10-year battery, which ends the need for battery replacements for the life of the alarms.

How to Replace Smoke Alarm Batteries?

Do Smoke Alarms Work Without Batteries?

Present times smoke detectors are wired on one circuit, which means these alarms will in any case work regardless of whether the batteries are dead.

A hardwired smoke detector seem like equivalent as a smoke alarm that is battery-powered when it’s on wall or roof, its consistent electrical current restricts the chance of failure.
