Front Panel
The LSI-16/LSI-16e features twenty-three LEDs on the front plate (from left to right).
Power
The first LED on the left will illuminate green if the unit is powered by main or PoE supplies.
General Alarm
This LED will illuminate red if the LSI-16/LSI-16e receives an alarm signal from an external emergency
detection system (e.g. a fire alarm system) via the Alarm inputs to the LSI-16/LSI-16e. This LED indicates
the general alarm state:

Solid red - The LSI-16/LSI-16e has received an alarm signal from an external emergency detection
system (e.g. fire alarm system).

Flashing red - The LSI-16/LSI-16e has received a general alarm silence from an external emergency
detection system (e.g. fire alarm system).
General Fault
This LED will illuminate yellow if there is a fault in the system that does not affect the delivery of a warning
message.
Power Supply Fault
This LED will illuminate yellow if LSI-16/LSI-16e is operating on a PoE supply but the main 24V supply
fails or an external power supply fault is signaled to the LSI-16/LSI-16e.
Protection Fault
This LED will illuminate yellow if a system amplifier channel fails and this failure does not prevent an
emergency zone voice announcement. Note: failures that do affect emergency zone voice
announcements will result in a system fault.
Path Fault
This LED will illuminate yellow if a fault in a transmission path is detected. The path integrity is tested from
microphone capsule to end of loudspeaker lines if optional Vocia ELD-1 devices are fitted at the end of
the loudspeaker lines.
System Fault
This LED indicates the integrity of the system:

Flashing yellow - The unit has a fault that may prevent the reliable operation of life safety
announcement functions.

Not illuminated - The unit is operational without any faults that may prevent reliable operation of life
safety announcement functions.
Because it indicates a potentially serious condition, the presence of a System Fault extinguishes
indicators for PSU, Path and Protection faults so as to focus attention on the primary fault. However,
individual PSU, Path and Protection faults are still shown in the system software and signaled to
individual fault outputs as described below. The LSI-16/LSI-16e will always power up in the system fault
condition. Manual intervention is required to take the LSI-16/LSI-16e out of this condition. Note: this
power up condition does not prevent emergency zone voice announcements provided that the system is
operating reliably.
