What is T tapping in the context of fire alarm systems?

T tapping refers to a method of wiring that can lead to incorrect functioning of fire alarm systems, particularly with initiating devices such as smoke detectors or pull stations. When T tapping occurs, a T connection is made to the wire, which can introduce issues such as voltage drops or problems with circuit integrity. This kind of improper wiring is significant because it may cause devices to malfunction or not operate as intended during an emergency situation. Ensuring proper wiring techniques is crucial for the reliability and effectiveness of fire alarm systems, making it vital for fire inspectors and technicians to understand the pitfalls of T tapping and avoid such practices in installation and maintenance.
