∙ 11y agoA bi-metallic strip in a fire alarm will bend when heated, due to different coefficients of expansion in the two sandwiched metals. When it bends far enough, the metal makes contact with another conductor, closing a circuit and setting off the alarm.
In another type of fire alarm, expansion of the metal occurs when a fusible link is placed under stress from a spring and the metal is heated to a calibrated temperature. When the temperature is reached, the expanded metal fails under the stress, opening a gap that can release a mechanical lever or open an electrical circuit.

Why is expansion of solids put to use in a fire alarm?
If a material expands as it is heated, then it could be configured to trip an alarm, or more likely a water valve for the sprinkler system, even if there is no electricity. Another way is to have an alloy, designed to melt at a specific temperature, to trigger the action.
What do you do when you discover a fire?
Evacuate, raise the alarm, try to put the fire out.
What are the of objectives of thermal expansion in solids and liquids in everyday life?
one example of thermal expansion is when in the kitchen and you can not open a can of vegetable(example) you will put it in a pan of hot water and the water will push it off.
Can you hang or put anything on a fire alarm pull station?
No! You can't hang or obstruct a fire alarm pull station at any time. To do so would mean you are breaking Health & Safety Regulations (and would probably invalidate your insurance, should there be a fire).
How do you put out fires on sims 2 ds I have tryed the water gun but it wont work QUICK PLEASE HELP i need help fast?
Buy a fire alarm from buy mode and put it near your cooker (or wherever else you get these fires), then when you get a fire, the alarm will go off, your Sim will start screaming, but then a fire man will come into your house and extinguish the fire for you.
What you should do in event of a fire in the lab?
You should LEAVE. Keeping your exit open in case the fire can not be controlled - find and use a fire extinguisher - give the alarm !
What is a class E fire alarm system?
Class E fire alarm systems are designed specifically for high-rise office buildings. These systems were put into place after multiple disastrous fires in high-rise buildings. The class E systems are designed to alert all areas of the building to a possible fire.
Should you go upstairs during a fire alarm?
The answer depends upon your situation! If you are in a basement of a dwelling, and the fire exit is upstairs, then it would be wise to go upstairs to exit when the fire alarm sounds. If you are below decks in a ship, going upstairs may also be the only way to get to safety when an alarm sounds. In other situations, where you are already at the ground floor or above, going upstairs may be a poor choice. However, there are high-rise alarm systems that will, in fact, direct some people "upstairs" away from a fire, at least temporarily. In theory, this allows firefighters time to enter and put out the fire. In reality, it may put occupants at a higher risk by moving them further from the only workable exits, at the ground floor.
In sims life stories how do you start a fire?
Just start cooking something on your stove then when it is cooking cancel the activity or whatever and make them do something else so they wont go back to it. If you don't want to put it out don't put in a fire alarm.
How do you stop a fire alarm when it starts beeping and there is no smoke?
You can stop a smoke/fire alarm beeping by removing the battery. But, get another or fix the one you have and put it back quickly as it can save your life. If it's also a CO2 detector you will see no smoke and smell nothing but CO2 is lethal if you continue breathing it.
Do some fire alarms squirt ink when pulled?
I am a great person to answer this question because I own my own fire alarm system (I put it together myself). The reason some fire alarms (depending how sophisticated and advanced the alarm system is) squirt ink is due to the fact that, say for example, some decides to pull the fire alarm at a school, it will leave a dye on your fingers you that you can't see, but the authorities can. They may arrest you for calling in a false alarm, and wasting the fire department's time. It really does not "squirt" the ink. As it simply just sits on the handle of the fire alarm. Basically how it works is they put a little vegetable based dye on the pull station handle and when the person who pulled it pulls it they will get the dye on their hands. The trick is when they attempt to wash it off of their hands , it only spreads and gets worse! This way police or whoever can easily identify the culprit because of their unusually blue colored hands. And it stays on for 48 hours!
How do you die in sims bustin out?
You can either build a room with nothing in it and put a door on it ,then make the Sim go in there and when there in the room delete the door. It will take a while but they will die. Or you could somehow make a fire with a fire alarm above it. Before the fire department gets there, the Sims you want to kill, put them in front of the fire just standing or extinguishing it.
