FIRE SAFETY
TECHEDGE
Fire detectors : Playing the vital role
Detectors have one goal to detect a fire. “They are not very different from one another. The main criteria is determined by the area it is meant to protect, which is the width and the length of the room.
Designing the fire alarm systems & signaling systems for better performance
Like sprinklers, today’s fire alarm and signaling systems are often designed for a specific mission. Building codes, fire codes and life safety codes have requirements for the use of fire detection, alarm and signaling systems in certain occupancy or use groups.
Fire alarm systems in existing buildings
In general, notification appliances do not require any compatibility listing. They must simply be matched for the proper voltage. There are two types of notification appliance that would require compatibility listing to the control unit. The first is addressable notification appliances. They must be compatible to ensure proper communication with the control unit.
Using a systems approach for reducing response time
The basic system and its interface module monitor the pressure gauge signals and contain the obstruction detection technology. The interface module with the specially enabled extinguisher allows a portable fire extinguisher to become a fully supervised component of a monitored fire alarm system.
Construction fire safety: Knowing the facts
A wide variety of ignition sources increase the likelihood of fires starting. Concentrations of combustible materials, incomplete compartmentation and other passive systems, and unfinished fire protection systems allow fire to spread unimpeded. Wind conditions can increase the rapidity of fire spread..
Vital factors in performance based design of facility fire protection
The sidebar on the right describes three possible examples of such designs. These three examples of performance- based design are hypothetical and simplified. Performance-based designs would normally use a bounding scenario (worst case) to the building.
Making the use of fire models in the design of fire alarm systems
Fire models can be used to perform several types of predictions. Models can be used to predict temperatures and velocities of fire plumes and ceiling jets, temperatures and thicknesses of hot smoke layers, and a variety of other fire-related phenomena.
Reliability of fire alarm systems
Every engineer responsible for the design of fire alarm systems should become familiar with the standards and processes of Underwriters Laboratories (UL) listing. The process provides a structure and oversight to the manufacturing process that greatly improves component reliability.
Making the right response to fire alarms
The number of nuisance alarms and their deterring effects have to be studied over a period of time. In a given building, three nuisance alarms in one week will have a greater deterring effect than three nuisance alarms over the course of a year.
The efficacy of duct smoke detection
The goals were to either support, change, or eliminate duct smoke detection requirements from the codes and standards, and to study the many myths about duct smoke detection. That research program has been completed, and reports have been issued. This article is a short summary of that work.
ELECTRONIC SECURITY
TECHNO FOCUS
Physical security : Gaining importance
Maintaining safe buildings and grounds while securing the network is critical for businesses. This is why safety and security solutions are gaining importance they give businesses access to the necessary tools and resources that enhance physical campus security, track assets, protect the network, and prevent unauthorized network access
Video encoders : The new wave
A video encoder is a device that is installed between an analog camera and an IP network. Its main function is to translate the analog video signal that comes into the encoder to a digital video signal (in MPEG-4, MJPEG or H.264) that then can be transmitted across the IP network and used with networked systems, servers and software.
Access control for mission critical spaces
Due to the recent demand by users for increased security measures, access control manufacturers have been integrating the characteristics of the standalone security systems into their access control systems.
Intelligent video solution: Making the right definition
An “Intelligent Video Solution” could easily be defined as “any video surveillance solution that utilizes technology too automatically, without human intervention, process, manipulate and/or perform actions to or because of either the live or stored video images
Security cameras: Evaluating the technology trends
Cameras using digital technology have much greater light sensitivity. Digital technology allows for extended shutter times for more light to be captured by the charge coupled device (CCD), producing pictures of scenes that are too dark for the human eye to see.
Access control systems : The best choice
In addition to managing entry and exit activity, today’s access control solutions add value by enhancing the security of a facility. For example, some access control solutions feature options to prevent the reuse of a card to access the same area within a specified period of time, or until the card is used to exit the area.
Integrating physical security
Before delving into the wide range of options for access control integration, it’s important to understand how our industry’s products have evolved to fully exploit network devices and connectivity.Second-generation access systems utilize intelligent remote panels that make local decisions when an access card is read.
Analaysing the security needs
Starting with a macro understanding of an organization and progressing to micro security tasks, it takes structure to compile and analyze a security plan. The resulting series of recommendations are orchestrated to complement and support each other
Understanding the converged access control solutions
Convergence uses data generated by both physical security and IT systems to drive both business process efficiency and security, and its framework defines a migration path for organisational growth. Here are some basic elements required to ensure a solution is truly converged.
The benefits of biometric access control
The benefit of a biometric access control system is that only authorised people not merely their credentials are granted access to specific places. A card-based system will only control the access of authorised pieces of plastic, but not who is in possession of the card, which can be shared or stolen.
