When in manual override mode, all points displayed on the ACM-24AT or
ACM-16AT and all its expanders will ignore subsequent Control-by-Event
(CBE) commands from the panel.
Manual Override Mode can be entered by pressing the Manual Override switch
on the ACM-24AT or ACM-16AT module (Use special slide-in label).
• The Manual LED on the ACM-24AT or ACM-16AT module will
illuminate steadily.
• The NFS-3030 will register an ANNUNCIATOR TROUBLE condition.
• The state of the each annunciator point will remain the same as before.
• The output circuits can now be controlled via their point switches.
The NFS-3030 Control-By-Event will not override the manual
control setting of the ACM-24AT or ACM-16AT module. To return
the annunciator to Automatic Mode, press the Manual Override
switch again (toggle action). Set the DIP switches on a Manual
Override annunciator as follows.The switch numbers given below are
for SW28 on the ACM-24AT, and for the 8-pin DIP switch on the
