Fire alarms installed throughout a building - are meant to be a first line of defense in protecting the lives of those within. Installed professionally, fire alarms work in tandem as a complex network dedicated to detecting danger in the form of smoke and fire. But just as important as the alarms themselves is the manner in which they are installed. In order to ensure the utmost efficiency and safety measures, it is imperative that a professionally licensed engineer complete a comprehensive fire alarm design.We all know that a fire alarm is used to detect smoke or heat in the form of fire and alert us to the danger so that we may vacate the presences in enough time to secure our safety. A fire alarm design takes into account the layout of the building including number of levels, heat sources, and exits; and it also considers the level of complexity required for each particular building. For instance, a single family home will require a far less involved fire alarm design that a multi-tiered sporting arena. In a large public building additional fire safety features will be required such as ceiling sprinkler systems and elaborate communications devices that are not required on private properties. An engineer will take all of these needs into consideration when completing a fire alarm design.The engineer and fire alarm technicians as part of making the fire alarm design - will review the specifications on each property and determine where the fire alarms should go to maximize their efficiency and allow for the greatest safety assurances. A drawing will be completed of the property showing exits, proposed locations of fire and smoke alarms, as well as any wiring or electrical needs that may result from this installation.Of course, in the case of a larger public building, the engineer and fire alarm technicians will work in tandem with licensed electricians who will handle the wiring and ensure that the installation is up to code. In many cases both in public and private buildings the fire alarm system will be connected straight to area fire officials who will monitor alarm activity. This ensures that help is on the way as quickly as possible maximizing the safety of all inside the building.When done properly by experienced and knowledgeable professionals, a fire alarm design will be a carefully crafted plan that will ultimately safeguard a building and the people inside.
Before you buy an electric rc helicopter, there are things you need to know.Here are the pros and cons of electric "rc helicopter" ProsElectric RC helicopter is one of the more favorable kinds of rc helicopters out there in the market for several reasons:It is easy to flyIf you are beginning to take interest on rc helicopters, then the best way to a good start is to buy an electric rc helicopter. It is easy to fly since it only requires batteries for power. You dont have to deal with engines and engine malfunction. You also dont have to buy gas to make it fly. With electric rc helicopters, you dont have to have knowledge about how engines work. You dont need to tinker complicated moving parts since there is none. All you need to know is where the controls and your rc is flying in no time.It is quietOther rc helicopters, especially the gas powered, create a lot of noise. And this is often times annoying not only to you but also on your neighbor who wants to get some quiet moment alone. Thus, you cannot fly them around your neighborhood. The good thing about electric rc helicopter is that it creates no noise at all. Without an engine, your rc will fly silently anywhere you want it to fly without disturbing the peace.It is safeBatteries are generally safe to use. This also goes with electric rc helicopter. All you have to do is to recharge it when it is empty and it will be off again in the air. You dont have to deal with flammables and you dont have to deal with engine at all.ConsJust like any other products, electric [*_*] has its drawbacks. Here are those:The experience is less excitingFull-size helicopters have engines and no helicopter is powered by electric current. So you cannot get a helicopter-like experience if wit electric [*_*]. The engine noise adds up to the experience. Without it, it may be boring.Activity is limitedWith electric [*_*], all you have to do is charge, fly, re-charge, fly, re-charge again, and fly again. Until you get to hate it. Like what was said earlier, you are limited to flying. Aside to that, no more.Other RC like gas [*_*] is more than flying, you get to tinker with the engine and in the process, get more excited every time you fly.
It is common for jewelers, craftsmen and quality controllers to use magnifying glasses to enlarge the appearance of an object they are analyzing. At the home, people with near vision difficulties are able to enhance their vision with a magnifier. With this, the text on a page will seem larger, and therefore easier to read.While magnifiers function well, handheld magnifier lights are useful to project adequate light onto an object for greater clarity. In fact, with more light used, it is possible to use a lower magnification power and thus work on a wider field of vision. This occurs as the field of vision of a magnifier decreases as magnification power increases.Handheld magnifier lights are great as they are small and portable. This means they can be taken along and used whenever needed. Apart from that, they are fitted with bulbs that project the right amounts of light with minimal shadowing. While non-portable desktop or standing magnifying lamps usually use 22 watt incandescent lamps for lighting, these are too large for their handheld cousins.As an alternative, bright LED lights are used for these magnifiers that are usually powered by AA or AAA size batteries. In order to conserve energy, they can be turned off and on and only used to illuminate objects in low light condition, or when lower magnification power is used.While LED handheld magnifier lights cost less than $20 each, a more expensive version Xenon handheld "magnifying glass" , costs between $60 and $100. These lights are extra bright and are great when extra lighting is needed for work.When using handheld magnifier lights, its best to hold the magnifier as close to your eye as possible. Then turn on the light and slowly bring the object from a distance towards your eye until it comes into focus. With this, you will be able to maximize the view and at the same time reduce image distortions.
This is the way that Network General (the creator of Sniffer ) has deployed Distributed Sniffer since the beginning. While the product that you are using may be from another or Open-Source vendor,( i.e. Ethereal / WireShark ), this process is time honored and as such, is considered to be Best Practice.This design is meant to assure that the NIC that is listening to the Monitor is not sending any packets itself. The Monitor Card should have no protocols bound to itself and listens in promiscuous mode. Additionally, the PC should be as passive as possible and not phoning home to vendors because of unnecessary software it has loaded.One process is to take a companys standard laptop and customize it by removing anything that is not needed to support the role of a Protocol Analyzer. Any software that is not part of the laptops OS requirements should be un-installed. Once the laptop has been stripped down this way, load the Open Source Protocol Analyzer of your choice and test it.Once testing is satisfactorily completed, save an Image of the laptop to be used to generate other Open Source Laptop Protocol Analyzers.System Requirements:Pentium 4 or higher.1GB Memory or higher.2 NICs. One of which is 100Mbs (not Gigabit) to be used as the Monitor Card. (NOTE: This process is not appropriate for Gigabit Monitoring.)Remote Control Software (i.e. VNC) that supports File Transfers from the laptop acting as a Protocol Analyzer to the PC used by the Network Transaction Analyst.Two NICs:1st NIC Monitor Card No IP bound to the card. This card just listens in promiscuous mode. It is the one that is attached to the Monitor Port in the Switch. This should be a 100 Mbs NIC.2nd NIC Transport Card IP is bound (static) so that this card can be used on the Intranet to access the remote control function of the PC. This can be Gigabit if that is all that is available.Other Configuration Issues:No Management Software (SMS, Radia, etc.) enabled. No management of this device other than remote control.Virus Protection (only if it is considered mandatory by company policy). However, this laptop should have no email client or any other software that will want to connect to the Internet (with the possible exception of Time Services). A Firewall rule can always be created to enforce its isolation from the public Internet except on approved sockets.A Time Server should be in place to keep the various Protocol Analysis Laptops in sync. This can be an Internet source if Company Policy permits or a local Intranet source.The laptop should not be a member of the Company Domain. One logs into the PC itself, locally or via remote control.All Mirrors in switches are to be bi-directional.Consider creating a shared folder to act as a Trace File depository. This is not required, but can be helpful as these files can easily grow too large for many corporate email policy size limits.Use WinZip on the Laptop to allow compression of the large trace files to speed up transfer.
On April 27 2007 the Associated Press reported that the Caterpillar Corporation of Peoria, IL had been the victim of massive identity theft. The theft came in the form a stolen laptop containing employee information. Caterpillar employs over 90,000 people worldwide. All of them, in that instant, became potential victims of massive Identity Theft. The potential cost of that Identity Theft could be in the millions of dollars. The result? On the day the theft was announced Caterpillar's shares rose 76 cents on the NYSE.Depending on which source one listens to the number of incidents of Identity Theft range from 100 million to over 300 million every year and the problem is increasing. Now, the previous sentence is filled with qualifiers, uncertainties and suppositions... and that is part of the problem. It is almost impossible to determine the severity of the problem of Identity Theft. One of the major difficulties in determining the severity of the problem is that a significant number of incidents of Identity Theft, some experts say even the majority, goes unreported.What is needed is an identity Theft Scorecard. This Identity Theft Scorecard would be a tool that could be used to develop a series of Identity Theft countermeasures. The Identity Theft Scorecard should be a tool that provides solid, objective, impartial and rational KPI (Key Performance Indicators) to what can be a very emotion laden issue. With the information provided from these Identity Theft Scorecards an Identity Theft Metrics could be developed. This Metrics would be an empirically accurate measurement of not only the costs associated with Identity theft, but also the number and type of victims and, perhaps, the number and type of perpetrators. An Identity Theft Metrics would quantify threats and vulnerabilities and provide a means to begin to address those areas of risk. It would also, hopefully, provide a tool that could be used to determine the perpetrators of the crime and curtail their activities.Any accurate Identity Theft Metrics will have as its core KPI a measurement of risk, not uncertainty. Risk is manageable, uncertainty isn't. Once areas of risk or vulnerability are known they can be quantified and proactively addressed. What cannot be measured is the unknown, the supposed or the hypothetical. It is possible to become so obsessed with the what ifs that the primary task, the combating of the actual and real threats, is neglected. Thus it is vital that a central premise of the KPI deals with real, not imagined, risk.As the economy is increasingly digitized and the vulnerability of people and corporations to Identity Theft increases, quantify the risks. Only by developing a real, measurable, empirical Identity Theft Metrics with measurable KPI at its core can we hope to deal with the issue of Identity Theft in an effective manner.
