On the display
The display reads Fault indication after 8 hours of isolate. The manual lists this wording as the only form of the message, and it appears as a fault indication on the panel.
What it means
This indication comes from a function that must be programmed under custom control so that the panel complies with AS 4428.1. The function is contained in the configuration templates: when it operates, the panel gives a fault indication after an isolate has been in place for 8 hours. The manual lists it among the required features for the panel, and the configuration templates for the 4100ES-S1 all contain the necessary equations for these functions.
Why it appears
- An isolate has been in place for 8 hours.
Setpoints and thresholds
- Isolate duration: the fault indication is given once an isolate has been in place for 8 hours.
- The function is contained in the configuration templates for the 4100ES-S1; the manual states
These settings should not be altered except under advice from Simplex.
- Features that are statutory in AS 4428.1 must not be pass-code protected — the manual gives zone isolate and zone test (Fault and Alarm) as examples.
Questions engineers ask
Why does my Simplex 4100ES show Fault indication after 8 hours of isolate?
Because an isolate has been in place for 8 hours. At that point the panel gives a fault indication through the function that AS 4428.1 requires it to programme under custom control.
What is the Fault indication after 8 hours of isolate function on the 4100ES?
It is a required AS 4428.1 function contained in the configuration templates: after an isolate has been in place for 8 hours, the panel gives a fault indication.
Can the 8 hour isolate setting be changed on the 4100ES?
The function is contained in the configuration templates for the 4100ES-S1, and the manual states that these settings should not be altered except under advice from Simplex.
