If dip switch is disabled in the fire alarm control panel, can it make a fault disappear, such as an earth fault?
Thank you, M B
An "Earth Fault" or "Ground Fault" light is a warning light on the fire alarm system saying "Somewhere in the building, electricity is leaking to the earth (ground)". The Earth Fault usually isn't in the box-on-the-wall called the fire alarm panel; the Earth Fault is usually on a wire connected to the fire alarm control panel.
Making a fault light disappear is like going around a "Road Closed" barrier, and then driving as fast as you can. You never know what is going to happen, but whatever happens is bad.
Do Not Disable a Fault Light or Cause It to Disappear.
This is a fire alarm system troubleshooting issue; you have to fix the fault, not turn off the warning light.
If you're not familiar with troubleshooting, get help.
Based on his electronics training, and his understanding of Life Safety, Douglas Krantz has compiled his knowledge of Conventional Fire Alarm Systems into the book Make It Work - Conventional Fire Alarms
. The book covers the basics of the Conventional Fire Alarm System, and shows how Life Safety and internal supervision affects the fire alarm system.
