Especially for Technicians Wanting to Know Why
In fire alarm systems, Addressable Signaling Line Circuits (SLCs) seem hard to understand, especially knowing why the voltage readings are unstable, why T-taps can be used in Class B circuits, and how detectors and modules send their alarm signals back to the control panel.
The book “Make It Work – Addressable Signaling Line Circuits” explains the voltage instability, the T-tapping, why the addresses are needed, how the panel provides power to the modules, how the signals are sent and received, how to troubleshoot the circuit, and more.
