How to carry out an FMEA on a smoke alarm .?
816281
In order to perform a design FMEA, you need first to divide your global system (smoke alarme) in subsystem (captor, alarm, transistor, etc...).\nThen you need to find all the functionnalities of each system (ex: captor : detect smoke)\nThe Failure mode is then defined by the functionnality absent, partially functionning or giving a wrong indication ( smoke not detected, alarm on but no smoke, etc...)\nThe effect is what will happen to the end customer for the system or the upper system for the subsystem.\nOccurence is how often this can occur (usually use data from customer complaints or return or manufacture capabilities)\nYou then try to detect the causes, they must come from a subsystem malfuncting or noise factors.\nDetection is how do you prevent or detect this failure mode to happen.\nUse the same scale for severity, occurence and detection.\nCalculate RPN by multiplying the three.\nPut an action on Higher number.\nTry to do it with a group, this is the main advantage of a FMEA: give the team a consensus about the problems that can occur.\nThe group will have to find the solutions.

I would just put a mouse trap in my lunch bag.  I think you'll want an alarm the detects light or motion.  If it just detects light then anyone who opens the bag will set off the alarm.  If it detects motion (without using a camera) then anyone who touches it will set it off.  The parts you need will be at Radio Shack.  You'll have to find someone who knows electronics to design the circuit for you.  You should only need about ten parts though.

just breathe second hand smoke... that should do the trick

You should take care of getting out of the house first,then call 911....your house is on fire!\n\nDid I get that right?

Spray on coating or clad in fire protective material.\n\nNot sre what your question actally is though :-)

If you find the key to the "V-door" and use it to get into the step house and get the "warm tube of grease" then you will have to get the "company truck" to take the bit to the catwalk.  After that check the level of water in the "crown cooler" and take this fire extinguisher around location "without setting it down" and don't trip over the "pipe stretcher".  Someone dropped that because they had their hands full of tools to take back to the doghouse including the "left handed 1/2 inch wrench" and the "metric crescant wrench".  Of course you could hold a bag of barite "over your head", but watch out for the "red river mites" on the shaker screens.\n\nWhat I am suggesting to you is to make your report about the tight knit community of oilfield workers and the pranks they play on the "worms", or the new guy on location.\n\nFeel free to write me on Yahoo ID xlr8n4d and I will tell you about some of the others that I mentioned.  Good luck!!!

you might have to activate later, the changes it needed to make to  your firewal might not fo into affect until it finishes installing

Look in the operaters manual

you guys are close. An alarm assignment is different in every Fire Department. What you get at each alarm depends on your Fire Department and how much apparatus they have. By calling for a higher alarm, you're getting more apparatus, and more manpower. It doesn't have to be 3 trucks for 3 Alarms. For example, if you've got a Engine and a Ladder Truck on scene and drop a 2nd alarm, you might get an additional Engine and a Chief. It all depends on what the ageny's SOP's are.

Write of call you state goverment office. Here in NY when you pass the firmens test you are sent to the Fire Academy. Check with your local goverment to. Try calling information in the biggist city near you. They should have a number for Fire Headquaters. Good luck, my husband  retired after 39 years on the NYFD

sure fire trick....rig up claymore antipersonnal mines around your house. Then put up a sign tell them to kiss your hiney.....wait for them to come on property...hit trigger......be sure to bury the body parts. If needing additional assistance contact your local marine...lol

Radon 360 makes excellent points, but not all systems operate in that fashion and you will find different regulations in different countries (and unfortunately in different provinces or states.)\n\nMost systems in the European community operate with closed loops circuits and an open circuit is an alarm.  In the U.S. it's bass ackwards, most systems close the circuit on alarm or lower the resistance on an initiaing circuit to the "alarm threshold".  There are pros and cons to both ways.  If the circuit remaining closed is a "safe" condition, this if something is inadvertently shorted or if a fire melts the insulation and the conductors touch, placing a short on the circuit, the system will fail to function properly.  Conversely, on a system that needs a circuit closure to activate, then a cut wire, or one conductor melted away would prevent proper operation.\n\nOutput circuits, or indicating circuits are a whole new ballgame.  Obviously, you can't have a "short" or the units would not get the power they need to operate.\n\nBottom line, most all fire alarm systems supervise both the initiating and indicating circuits in some fashion.  In the United States, Class "B" circuits use an end of line resistor or other device that the main control panel is constantly looking for, if it doesn't see it, it faults.  Class "A" circuits return the wires to the panel in a redundant fashion to build a fault tolerance into the system.  Technically Class "A" and "B" are old terms that have been replaced with "Style B and D" and "Style Y and Z" for initiating and indicating circuits respectively.\n\nIn the end, most diagrams are based on the information provided by the fire alarm control panel's manufacturer.  Their manual outlines the type of circuits the system is expecting and show example layouts that can be used to generate a specific system.  Some even offer CAD files that can be downloaded to assit to this end.  \n\nIf you are looking to design a system, consult a professional.\n\nIf you want to learn more about it, feel free to contact me direct.

Turn on windoes xp firewall start setting control panel then click on icon windoes firewall and turn it on if you have any other fire wall turn it on to. like zone alarm

The stove does a good job.  But take the battery out of the smoke alarm first.

I use one called a Smokey.\nCheck this one out on ebay...
