Display panel LEDs
The LEDs on the Gasmaster Display Panel indicate the
following:
Yellow Fault LED:
Lights when any detector or system fault is detected
(see page 23 for a list of fault messages). The fault LED
operates with the common fault relay, and can be set
as latched or non-latched dependant on the system
configuration.
Yellow Warning LED:
Lights when a warning condition is present (see page
25 for a list of warning messages). The warning LED will
automatically reset when the cause is cleared.
Green Power LED:
Is normally on when power is present, and will switch
off briefly once every five seconds to indicate that the
system is operational. The LED will flash on and off
every second when Gasmaster is operating from its
batteries due to power failure.
Red Alarm Bar:
Will flash when an alarm from any channel is triggered,
and will remain in a steady ‘on’ state when the accept/
reset button is pressed. The LED bar will flash again if a
new alarm is triggered.
