Bi-wire fire alarm systems (also known as two-wire systems) simplify installation by allowing detectors, call points, and sounders to share the same cable pair per zone. This reduces the amount of wiring and speeds up setup without compromising safety. Bi-wire systems are ideal for small to medium-sized premises such as convenience shops, community centres, and small offices. They offer a balance between the simplicity of conventional systems and the efficiency of addressable solutions.
