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 AM2020/AFP1010 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 AM2020/AFP1010 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
