Front Panel Switches
NEXT/ACKNOWLEDGE SWITCH
Acknowledges the receipt of new messages at the LSRA-C and
automatically advances to the next unacknowledged message. When
there are no unacknowledged messages, the NEXT/ACKNOWLEDGE
switch is used to scroll forward through the review buffer. The review
buffer only displays active points. Should a point go active then
restore, it will not appear in the review buffer.
BACK SWITCH
When there are no unacknowledged messages, the BACK switch may
be used to scroll in reverse through the review buffer. When the BACK
and NEXT/ACKNOWLEDGE switches are operated simultaneously
after all messages have been acknowledged, the LCD display is
cleared.
The following switches are available only on the "-C" series
annunciators. These switches may require a password in order to
operate. If the annunciator switch has been configured to require a
password, the password will automatically be requested AFTER the
switch is activated. Once a password has been entered, it is valid for
approximately 2 minutes.
RESET SWITCH
Reset directs the CM1(N) or PCPU to issue a system wide reset
command after all system wide status points have been acknowledged.
