Fuse Replacement; Replacing/Relocating Detectors - Visonic PowerMaster-10 Installer's Manual

5.4 Fuse Replacement

The PowerMaster-10 has an internal fuse (the PowerMaster-30 has two internal fuses) that has automatic reset.
Therefore, there is no need to replace the fuse(s).
When over current condition occurs, the fuse cuts off the circuit current. Upon fault current being removed for
several seconds, the fuse is automatically reset and allows current flow through the circuit again.

5.5 Replacing/Relocating Detectors

Whenever maintenance work involves replacement or re-location of detectors, always perform a full diagnostic
test according to section 3.9.
Remember! A "poor" signal is not acceptable, as stated at the end of the introduction to the test procedure.
