LED colour Description
System Fault LED Yellow Indicates a control panel system failure or that one
or more reported events (alarm, zone alarm, fault,
condition, etc.) exceed the maximum limit of 512.
See “System Fault LED indication – maximum limit
for event type reporting” on page 11 for more
information.
Sounder Start/Stop
Red
The LED indicates what happens when the button is
pressed.
If the LED is on (flashing or steady), pressing the
button silences the sounders.
If the LED is off, pressing the button activates the
sounders (if the control panel status and operating
mode allow manual activation of sounders).
The LED also indicates the status of the sounders:
• Steady indicates that sounders
be activated shortly)
• Flashing indicates that a delay is counting
(sounders are activated when the configured
delay elapses or when the delay is cancelled)
• Off indicates that the sounders are off (or will be
deactivated shortly)
To prevent the immediate silencing of sounders
when an alarm is first reported, the Sounder
Start/Stop button may be temporarily blocked when
a configured sounder delay is counting down. For
more information, see “Sounders silence disable
time” on page 125.
Depending on the size of the installation, processing
commands to start or stop sounders may take a few
seconds to travel through the system. This is why,
for example, the LED may be steady but sounders
may not initially be audible.
Panel Silence button and
Yellow Silences the control panel buzzer.
A steady LED indicates that the buzzer has been
silenced.
Reset button and LED Yellow Resets the control panel and clears all current
system events.
A steady LED indicates that the control panel can be
reset in the current user level.
