A good smoke alarm should have a power source from a battery so it is sure to go off in the event of a power failure. Be sure to test your smoke alarms regularly to ensure the batteries are in good working order.
Hearing a high pitched "beep" throughout the house? Check your smoke alarm! This annoying sound is their way of telling you to change the batteries or that something is wrong with it.
user comment: that doesn't really answer "why?" it goes off.
You don't want to rely on a smoke detector that doesn't have power. This is why some detectors have an internal battery that can alert you to a possible dangerous situation.
Photoelectric smoke alarms are also called optical alarms. They are more expensive than regular alarms. They are also more accurate and less likely to go off unnecessarily.
Nope... Only smoke for smoke detectors!
Not as such but available in retail are stoves that have smoke alarms built in and turn off when smoke is detected
By connecting smoke alarms together, triggering one will trigger the others, resulting in a better chance that everyone in the house will hear them going off and get out safely.
yes, if enough dust accumulates
Smoke alarms are hung so that if there is a fire you will know it. If toast is smoking then the alarm will detect it.
No it will feel captive.
One of the biggest expenses with maintaining smoke alarms is the cost of batteries. Since you don't want to let the batteries go for too long, you need to constantly cycle them out about every six months. Not only is this expensive, but it's a time hassle too depending on how many alarms you have. If you're looking to save some time and money, you may want to consider using photoelectric smoke alarms in your home instead of traditional battery powered ones. These photoelectric smoke alarms run off of a small photovoltaic cell that comes with them, meaning you never need to use batteries.
Smoke alarms are designed to sense smoke, which indicates fire, earlier than you may detect it if you are sleeping or in another part of the house. When the smoke alarm goes off, you know there is danger and can leave in time to stay safe.
They are devices that are made to sense changes in heat (heat alarm/fire alarm) which then activated either self sounders or complex alarm systems Smoke alarms detect chemical changes and as like heat set off either internal sounders or complex alarm networks
If you run an office, then one of the main security issues that is probably on your mind involves fire in some way. With so many office machines running at all times, there's bound to be a short sooner or later, and when it does you need to be protected. This is why it's important to have interlinked smoke alarms in an office. If the smoke alarm in the offending room is muted out somehow or completely disabled, you will still be alerted to the fire since a number of other interlinked smoke alarms will also sound off as well.
Having a generator for home power outage can help keep your family comfortable during a power outage. To determine the size of a generator, make a list of the minimum appliances you want to run off the generator. Next, make a list of the devices you'd like to run. You may have to alternate running some appliances such as the vacuum, computer and television for a smaller generator.
