Miniature Circuit Breaker (MCB) are designed to protect the conductors and insulation from damage due to over load and short circuit.The simplest way to visualize a miniature circuit breaker is to think of a load center in a home, the circuit breakers inside are miniature circuit breakers. Components MCBs are made up of 5 components …
The two types of low voltage (LV) busway are feeder and plug-in. They are commonly intermixed on runs of busway and plug into each other. Feeder Busway Sometimes called low impedance busway Used to feed power to a distant point Beneficial because the voltage drop over the run is generally low (somewhat lower than plug-in …
Busway is an economical, modern method of distributing electricity within a building. It is similar to the tracks that an electric model train runs upon, both in look and in function. Train track sections can be snapped together to form a number of different paths for the train to follow. Likewise, sections of busway can …
Electronic Access Control Systems comprise electronic elements, physical elements, operational elements, and logical elements to create a complete working system that facilitates rapid and reliable access to authorized users in a facility at minimum long-term cost to the organization. Access Control elements include: Users Access Portals Credentials and Credential Readers Credential Authorization Process Locks, Alarms, …
Access control concept is all around us. From the lock on your front door or car door to the Personal Identification Number (PIN) for your Automated Teller Machine (ATM) card, we encounter access control systems every day. access control is everywhere. Access Control Systems are designed to help ensure that only authorized or qualified people …
Hi-Tech systems include all electronic systems. Typically these include Alarm/Access Control Systems, Video Systems, Communications Systems, Integrated Security Systems, Specialized Detection Systems, and Computerized Systems. Hi-Tech systems serve to automate repetitive functions, monitor continuously without error, and report to and facilitate communication and coordinated response by security staff. Increasingly, Hi-Tech systems are used to handle …
There are three types of Security Countermeasures: Hi-Tech, Lo-Tech, and No-Tech. These three must be used in combination to create a layered and effective security program. No single security countermeasure is effective against all threat scenarios. Access Control Systems, in particular, are a type of “controlled vulnerability” as each access control portal is a hole …
Designing an access control system can be a daunting task, especially if the system required is substantially larger than what is already in place. But if you approach it methodically, you can reduce error and ensure that you get the exact system needed for your facility. Assess the Situation Observe Your Environment Conduct a Site …
Hand geometry recognition systems are commonly available in two forms: full hand geometry systems that measure the entire hand, and finger geometry systems that measure only the index and middle fingers. Hand and finger geometry biometrics are automated measurements of hand and finger dimensions taken from a three dimensional image. A reader or camera captures …
Fingerprint recognition is one of the most widely used biometrics in the access control industry.This is because fingerprints are one of the oldest forms of personal identification, inexpensive to collect and analyze, and they are stable. Biometric fingerprint access control applications use one or both of two fingerprint characteristics: ridge patterns and minutiae details, which …
