Bi-Directional Amplifier (BDA) Systems

[IDG-02-006]

Bi-Directional Amplifier (BDA) Systems is a term that frequently refers to Emergency Responder Communication Enhancement Systems (ERCES). The purpose of these systems is to ensure hand-held radio coverage in buildings for first responders. Firefighters are first responders, but the term also includes police and emergency medical personnel. ERCES were developed due to the lack of in-building communication during operations at the World Trade Center terrorist attack on September 11, 2001. The design and installation of BDA systems are required to be performed by qualified individuals. The operation of BDA systems, or lack of, can result in the loss of life.

Ohm's Law

Ohm’s Law is a formula that was first published in 1827, and was derived from the observations of the relationship between voltage, current and resistance that was made by Georg Ohm. Ohm’s Law is used in the design of electrical circuits; the troubleshooting of electrical circuits using measurements compared to known values; and calculating the proper battery and power supply sizing. Ohm’s Law applies to any device, equipment, or component that is electrical in nature. Knowledge and practical application of Ohm’s Law is a skill that will enhance electrical competence.

Fire Alarm System Fundamentals

The purpose of fire alarm and signaling systems is to protect life and property. NFPA 72, the National Fire Alarm and Signaling Code, provides the requirements for the basic functions and fundamentals for fire alarm systems. Fire alarm system fundamentals govern the aspects of the equipment; system design and installation; the qualification requirement of personnel; power supplies; and system signals. Documentation is a fundamental, and the topic is covered in its own course; Fire Alarm System Documentation.

Protected Premises Alarm Systems

The Protected Premises Alarm and Signaling System is the basis of all other systems found in the National Fire Alarm and Signaling Code, NFPA 72. The requirements for a Protected Premises will apply to fire alarm systems and signaling systems that utilize voice instructions during non-fire emergencies. The purpose of a Protected Premises Alarm and Signaling Systems is to protect life and property from the losses due to fire within the building they are installed, and NFPA 72 allows Dedicated Systems. Dedicated systems will perform emergency control functions to enhance the survivability during a fire when building codes do not require a fire alarm system. The features of a protected premises are the basic fundamentals that are found in dedicated systems, fire alarm systems and emergency voice and communication systems.
