LED Indications
WES3 Maintenance Interface
Green LED
Active units with no faults will flash their green LED once every 4 seconds to
indicate that the unit is operational.
Amber LED
Each WES3 unit monitors itself for a number of faults. These are indicated via the
amber LED, which will flash in grouped patterns with longer than usual gaps in
between them.
Units displaying one of these patterns require further investigation and should not
be relied upon as part of the fire alarm and detection system until the fault has
been corrected. Use the chart at the bottom of this page to determine the nature
of the issue.
Red LED
The red LED will flash every 4 seconds when the unit has been triggered.
Group Flash 1 - Low Battery
Group Flash 2 - Low Signal
Group Flash 3 - Unpaired / No Signal
Group Flash 4 - Tamper
Group Flash 5 - Unit Latched
