What is a fault or fault condition?
A fault or fault condition is when a zone is open on an alarm system. If you have nothing wired into your Honeywell panel when you first turn it on; you’ll get a plethora of fault conditions.
When you do finally wire things into your Honeywell panel you will get a fault when, for example, a door or window is open. Also you will get fault conditions when a motion sensors senses motion. It’s just basically the alarm panels way of saying a device has been activated.
You can also get fault conditions if you have programming wrong, a wire has a break in it or a resistor has been omitted when a zone has been told, through programming, that it needs to use one.
