Two commands are available to stop the alarm and fault buzzer from
sounding - for example, during commissioning, annual surveys, or fault
finding. Using these at either the
MX1
panel or the remote FBP will
disable/mute the buzzers at both units, except for keypress beeps.
Buzzer Mute: This is a temporary buzzer mute function and lasts for
24 hours or until the mute is cancelled
– manually or by power down
or restart of the
MX1
. Note that this will stop the buzzer from
sounding for any alarms and fault conditions.
Buzzer Disable: This function is an Access Level 3 command and
lasts for as long as the buzzer is disabled.
From the base display press TESTS then select
INITIATE
F4 option
and MENU to show the
