Where should smoke alarm system be place in a home?
Smoke alarms need to be outside of each bedroom on the ceiling.
Others have found that additional smoke alarms must be places INSIDE each sleeping area to be loud enough to wake up someone there, or to detect smoke from a fire inside the room.
In non-dwellings, various fire codes and life safety codes determine the minimum number of smoke alarms and where they must be placed.
How do you make a working model of a fire alarm?
Strip the insulation off of the ends of the wires so that the metal is exposed. Connect two wires to the alarm's positive (+) and negative (--) terminals and the other two to the battery's positive (+) and negative (--) terminals.
Secure both the alarm and the battery to the plywood using glue or electrician's tape. They should be spaced apart, but still close enough for the ends of the wires to touch.
Wrap the end of the wire connected to the positive terminal of the alarm to one of the jaws of the clothespin. Do the same thing with the wire connected to the positive terminal of the battery to the other jaw. When the clothespin closes, it should cause the two wires to touch each other.
Cut a piece of paraffin wax big enough to fit between the jaws of the clothespin. Wedge it in place so that it doesn't move, securing it with a rubber band if necessary.
Attach the clip to the plywood using glue or electrician's tape.
Connect the ends of the two remaining wires to each other. At this point, the only thing preventing the connection is the wax. When the temperature gets high enough to melt it (about 120 to 160 degrees F), the jaws of the clothespin will close and the circuit will be completed, starting the alarm.
How often should you test the smoke alarm?
Smoke alarms should be tested at least once a month. All smoke alarms have a test button that you push to check out the entire alarm, including its sensitivity (how much smoke it takes to set it off). If the testing mechanism does not work properly, the alarm should be replaced immediately. Never use open flame devices to test an alarm.
Older adults and the physically impaired may have problems reaching their alarms to test them. There is one brand of smoke alarm on which the test feature can be activated by shining a flashlight on it. Another brand has an automatic test that activates at the same time and day, once a week. These models can be used where proper testing might not otherwise be done.
Smoke alarms need no maintenance other than changing batteries (in those that have batteries) and an occasional vacuuming of dust or cobwebs. Every smoke alarm comes with a homeowner booklet, which describes how to use and take care of that particular alarm. You should read that booklet and keep it in a safe place for future reference.
What percentage of Americans has at least one smoke detector in their home?
According to NFPA research, 96 percent of US homes have at least one smoke alarm. Unfortunately, at least 23 percent of them are useless because they do not have working batteries.
Homes with smoke alarms that don't work now outnumber homes that don't have any smoke alarm at all.
Two thirds of deaths in fires in the home occur in homes without working alarms.
What is the penalty for pulling a fire alarm in New Jersey?
Any person who violates the provisions of N.J.S. 2C:33-3 shall be liable for a civil penalty of not less than $2,000 or actual costs incurred by or resulting from the law enforcement and emergency services response to the false alarm, whichever is higher. Any monies collected pursuant to this section shall be made payable to the municipality or other entity providing the law enforcement or emergency services response to the false alarm. "Emergency services" includes, but is not limited to, paid or volunteer fire fighters, paramedics, members of an ambulance team, rescue squad or mobile intensive care unit.
How are alpha particles used in smoke alarms?
Alpha radiation is emitted from the amercium button in a smoke detector. When smoke goes into the smoke detector it blocks the stream of alpha particles emitted from the americium. That triggers an alarm.
What do you do if you hear a smoke alarm in your house?
If you hear a smoke alarm, everyone inside the building should be evacuated to a safe area (assembly point). If smoke or a fire is present, the emergency services should be alerted using a mobile phone or the neighbours telephone. No one should enter the building to collect valuables or pets. This is the job of the fire crew. If you are trapped inside the building call for help out of a window. This will attract attention and you will be helped. If you are trapped in a room, always check the temperature of the door handle before opening the door, as the fire could be on the other side. If the door handle is hot, place a fabric in the gap between the door and the floor at the bottom to prevent smoke from entering. If the door handle is cold, proceed out of the room, looking out for the fire. Keep low, as the smoke will rise, stopping you from inhaling smoke. Leave the building as soon as possible.
It is always good to set out an assembly point with your family in case of any fires.
NEVER RISK YOUR LIFE TO COLLECT ANY VALUABLES OR PETS AND CALL 911/999 IMMEDIATELY!

How many lives has the smoke detector saved?
A self-contained residential smoke alarm lasts about 12 years, but must be replaced no later than 10 years for safety. Some units now have a 10-year battery life or other features that cannot be extended, thus requiring it to be discarded and replaced at 10 years.
How much does a fire alarm technician make?
Not enough
Actually, this answer depends on a number of different variables. If the employer happens to be a "union shop", you can expect some fairly good wages that would (more than likely) include medical benefits and a pension plan. I can speak for the industry in the lower mainland of British Columbia (Vancouver and environs). Many municpalities here require ASTTBC certification. A "Registered Fire Protection Technician" that holds certifications in the four main fields (FA - Fire Alarm, WA - Water Based Extinguishment Systems, EX - Extinguisher, and EL - Emergency Lighting Systems) can command an hourly rate of between $24.00 and $36.00 depending on the employer. There are several links to organizations that may give you more detailed information.
Where should a fire alarm control panel be sited?
It should be really located by an entrance exit for conveniant reasons. For example, when there is a fire alarm or a fire, the fire brigade can quickly access and see where abouts the fire has been reported to, instead of wondering around to find it in some random office, corridor some where.
Or you could have repeater panels, two panels that nearly look identical to eachother. The main panel controls the system on its own. It then corresponds the information from the main panel to the repeater panel where it is displayed.
Idealy, you should have some zone displaying panel by an exit so it can easily be accessed and looked at with the main panel being at a central office somewhere. Both ways are a good option.
What are the disadvantages of fire alarm systems?
The only thing we can think of is water damage that may result while the fire sprinkler is going off.
This doesn't seem as bad when you consider you could lose literally everything in a fire!
Another disadvantage is the installation cost (especially if retrofit), including creating an acceptable source for water pressure (if none is readily available), and the costs of periodic testing and mainenance costs. If the building is susceptible to freezing, there could also be costs associated with installing and maintaiing a "dry" system, or providing heat that would not otherwise be necessary, driving up the operating costs.
How many decibles is in a fire alarm?
The total sound pressure level produced by combining
the ambient sound pressure level with all audible notification
appliances operating shall not exceed 110 dBA at the
minimum hearing distance.
For sleeping areas, the sound level at the pillow should be 75 dBA.
Do you have to activate the alarm before rescuing persons in immediate danger from fire?
At the moment you notice fire you have to activate fire alarm and get away from the place. Otherwise you will not get help in time.
Does a fire alarm set off the sprinkler system?
Most standard fire sprinklers are activated by heat. There's a small bulb of liquid that keeps the water back in the pipes before a fire begins. When a fire breaks out, that liquid will heat up and eventually cause the bulb to burst, releasing the water from behind it.
Home Depot sells an array of smoke and carbon monoxide detectors, available from $20 to $150. To save space and installation, homeowners should consider a combination model.

What is the average power consumption of fire alarms?
The average power consumption of fire alarms typically ranges from about 0.5 to 2 watts per unit, depending on the type and features of the alarm. Battery-operated alarms generally consume less power than hardwired models, which may include additional functionalities like interconnectivity and voice alerts. Overall, the energy use is relatively low, allowing them to operate effectively without significant impact on electricity bills.
What to do if you hear a fire alarm?
1. If there is no fire or smoke evident in the hallway on your floor, remain in your unit.

Are manual fire alarm pull stations required?
Check with your local building department of your city or county. They will be able to tell you exactly what is required in your community.
Why does your smoke alarm upstairs makes a sound every 10 minutes?
The main cause of this is a low battery. Most smoke detectors are designed to send out a low beeping sound (sometimes followed by a flash of the red light in some but not all designs) when the battery is low, to make the home owner aware they need a new battery.
If your smoke detector is wired up to the mains of the house (as the new UK laws state they should be in new homes), then the beeping/chirping will still occur if the backup battery needs replacing.
Once you have changed the battery, you may need to hold the test button down for around 30 seconds, depending on the make and model of the alarm (refer to the manual).
If changing the battery does not resolve the issue, then there is likely dust or dead insects interfering with the alarm. You should clean the alarm with compressed air.
If the alarm is sticky from nicotine, you will most likely have to purchase a new one. Nicotine contains hydrocarbons - and so does fire and carbon monoxide. But nicotine is sticky and therefore almost impossible to clean out of the alarm filters. You should always avoid smoking in the same room as a smoke detector (or even better, don't smoke indoors at all).
Failing that, the alarm might be faulty. If it is a battery operated one, purchase a new one. Or contact your local fire station on the non-emergency number. In the UK, some people such as pensioners are eligible for free smoke detector replacements from the local fire service.
If it is an electrical one, contact the manufacturer or the local fire station on the non-emergency number.
