activated code prior to selection of a new code or proper preparation at listening posts. A new
code can be selected at any time during automatic operation and will commence after the 10
second delay. Termination of the Automatic Mode can be accomplished by either depressing the
“Auto On/Off” button, activating any of the Maneuvering Signal codes, activating the “At-Will”
button (the latter two will also cause instantaneous signaling of the device), or activating the
“General Alarm” button.
The M-511C has the ability to change the cycle times between restricted visibility signaling. The
default setting is 120 seconds between blasts, which is also regulation. When initially powered
up the 120 second LED on the “Auto On/Off” will be lit, signifying the 2-minute interval. The
other two intervals are 90 seconds, and 60 seconds. To change the signaling interval depress and
hold the “Auto On/Off” button for 5 seconds then release and the next LED will be lit, continue
this procedure until the desired interval is attained.
For quick easy signaling of required maneuvering codes the M-511C includes four (4) preset
codes with a descriptive reference included on the keypad. For a complete explanation of these
codes please refer to the attached reference sheet. When a maneuvering code button is pressed,
the horn will instantaneously signal the code and terminate the Auto mode (if on).
The M-511C is designed to be used as a single unit or in conjunction with other M-511C units,
and with multiple remote “At-Will” buttons, such as the Kahlenberg M-131A, M-126, or any
customer supplied two contact button. Refer to the wiring diagram included with these
instruction sheets for your particular application.
The M-511C is also equipped with a General Alarm code which is activated by depressing and
holding the “General Alarm” button for 3 seconds. This function will stop all other functions on
the M-511C and can only be stopped by depressing the “Auto On/Off” button. When the General
Alarm is activated all three LED’s on the “Auto On/Off” button will be illuminated at the same
time.
**NOTE: The “Horn 1, Horn 2 Select” button is inoperable on the M-511C. This switch
functions only when this unit is supplied with the Kahlenberg KB-30 Electronic Horn/Hailer
unit
