LED Codes
Green LED
Active units with no faults will flash their green LEDs once every 4 seconds
to indicate that the unit is operational.
Amber LED
Each WES unit monitors itself for a number of faults. These are indicated
3
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 below to determine the
nature of the issue:

Red LED
If a detector has raised the alarm, its red LED indicator will flash during a fire
alarm.
It is recommended that the fire system is tested weekly or whenever a
significant change has been made to the installation or the building under
construction. WES
test the radio link between units without activating an audible fire alarm.
You can therefore ensure each unit in the system has a robust radio link with
sufficient capacity to allow for environmental fluctuations without disturbing
the site.
