The research recommends school decision-makers use this new tool to evaluate and select communication and warning system technologies. It recommends a pilot project to test the implementation of the conceptual lockdown notification system in schools. Naval Postgraduate School U. Center for Homeland Defense and Security.
Listed on Active Shooters [Featured Topic]. By knowing the constant speed of light we can calculate the distance traveled. To get increased accuracy our laser process as many as sixty pulses in a single measurement period. Target acquisition times range will be half second. Sophisticated accuracy validation algorithms are in place to ensure a reliable reading.
The radiated light power of our lasers is on the order of 50 micro watts. The Laser security systems are high tech innovations that have gained popularity in home and office security systems. These are used to be expensive solutions for security needs. Depending on cost and fast technological advancements laser security systems becoming more adoptable.
The features and specifications of the laser security system can be had in detail from the security system dealers who provide high end solutions based on requirement. These are easy to install and work at both within as well as outside houses. These are very effective perimeter alarm systems around properties. In indoor systems can utilize the normal power outlets and jacks making them inconspicuous. At outside these can be easily be hidden behind the bushes or plants without causing any damage.
They Consume less power when compared to the laser system as the whole, which is expensive.
These laser systems can be installed in homes either by self or by hiring a technical person. By technological innovations cost of the security systems has been cut to a large extent. So, making laser systems one among affordable security system options can be very safe. It can be designed as a simple electronic project for demonstration in science exhibitions. It can also be made as a mini or major project for electrical or electronic students. When making this laser security system one can know all about laser beams and their installation.
While preparing a laser security system, we need to concentrate on the microcontroller program and installed with the laser beam device.
When using traditional photo resistors for preparing security systems one has to consider the natural light phenomena. Laser are strong in beam width and can be focused on the perfect target. By using laser security system one can be safe in the case of harmful effects to the body.
Security System Thesis for Research Scholars.
As the beam width used in the laser security systems are not strong beam widths. Which are used in the cutting devices.

If a sprinkler contractor has demonstrated success with these type of organizations, then they will be capable of performing satisfactorily in a heritage site.
The selected sprinkler components should be provided by a reputable manufacturer, experienced in special, water sensitive hazards. The cost differential between average and the highest quality components is minimal. The long term benefit, however, is substantial.
When considering the value of a facility and its contents, the extra investment is worth while. With proper attention to selection, design, and maintenance, sprinkler systems will serve the institution without adverse impact. If the institution or design team does not possess the experience to ensure the system is proper, a fire protection engineer experienced in heritage applications can be a great advantage. Water Mist One of the most promising automatic extinguishing technologies is the recently available fine water droplet, or mist systems.
This technology represents another tool that can provide automatic fire suppression in some cultural property applications.

Potential uses include locations where reliable water supplies do not exist, where even sprinkler water discharges are too high, or where building construction and aesthetics impact the use of standard sprinkler pipe dimensions. Mist systems may also be an appropriate solution to the protection void left by the environmental concerns, and subsequent demise, of Halon gas.

Mist technology was originally developed for offshore uses such as on board ships and oil drilling platforms. For both of these applications, there is a need to control severe fires while limiting the amount of extinguishing water, which could impact vessel stability. These systems have been extensively approved by a number of domestic and international marine organizations, and have been a protection standard for the past 8—10 years. They have a solid track record dealing with maritime fires.
These systems have also been used in several land based applications, and have a number of listings, primarily in Europe, where their effectiveness has been recognized. Some systems have recently received approvals for North American land based uses. Mist systems discharge limited water quantities at higher pressures than sprinkler systems. These pressures range from approximately to 1, psi, with the higher pressure systems generally producing larger volumes of fine sprays.
The produced droplets are usually in the 50 to micron diameter range compared to —1, microns for standard sprinklers , resulting in exceptionally high efficiency cooling and fire control, with significantly little water. Water saturation that is often associated with standard firefighting procedures is decreased. Other benefits include lower aesthetic impact and known environmental safety. This cost, however, may be reduced due to possible installation labor savings. In rural applications, where reliable sprinkler water supplies can be expensive, mist systems may be comparable or less than standard sprinklers.
Another problem is that these systems do not have the variety of approvals and listings commonly associated with sprinklers. As such, they may not be as recognized by fire and building authorities. In addition, the number of contractors who are familiar with the technology is limited. These concerns are diminishing, however, as use of these systems becomes more widespread. Summary In summary, automatic sprinklers often represent one of the most important fire protection options for most heritage applications.
The successful application of sprinklers is dependent upon careful design and installation of high quality components by capable engineers and contractors. A properly selected, designed and installed system will offer unexcelled reliability. Sprinkler system components should be selected for compliance with the institution's objectives. Wet pipe systems offer the greatest degree of reliability and are the most appropriate system type for most heritage fire risks.
With the exception of spaces subject to freezing conditions, dry pipe systems do not offer advantages over wet pipe systems in heritage buildings. Preaction sprinkler systems are beneficial in areas of highest water sensitivity. Their success is dependent upon selection of proper suppression and detection components and management's commitment to properly maintain systems. Water mist represents a very promising alternative to gaseous agent systems. The following information sources are available to assist with selection of fire sprinkler systems:.
