9-6 Magnetic Locks LC 1200 Manual
Adjusting the Sensor Pin
Accurate adjusting of the Sensor pin will help
prevent nuisance alarms from slight disturbances
and small vibrations such as someone bumping
into the door or someone shutting a door nearby.
To adjust the Sensor pin, refer to Figure 9.1 - 9.3
and use the following instructions:
1. Remove power from the Lock by
powering down the LC unit.
2. Remove the cover to the Lock housing.
3. Remove the Fire Alarm Control jumper
from the Lock.
4. Make sure DS1 (the Lock selector
switch) Position 3 is in the OFF
position.
5. Move DS1 Position 1 to the ON position
NOTE: The ON position denotes “set-
up” mode.
6. Be certain that the Set screw in the
Sensor Ring is loose and will not make
contact with the Sensor pin (Figure 9.3)
WARNING: Failure to follow this step
can damage the threads of the Sensor
pin as you make adjustments.
7. Start with the Sensor pin adjusted out as
far as possible while still solidly
threaded into the Sensor ring.

8. Apply power to the Lock by powering
up the LC unit. The Lock LED will light
up both Green and Red (kind of Yellow)
while it goes through its power up
sequence (about 5 seconds)
9. When the power up sequence is over,
the LED will either turn solid Red (Door
closed and locked) or the LED will turn
off (Door open and unlocked). You want
the door to be closed and locked.
10. With the door closed and locked, apply
as much pressure to the door as needed
to fully deflect the door, and while
holding it in this position, adjust the
Sensor pin with the included ¼ Allen
wrench until the (Red) LED goes out on
the Lock.
NOTE: For slight adjustments, there is
a Sensor pin access hole in the PCB of
the Lock. However, depending on how
the internal lock wires are situated this
may not be feasible. If this is the case, it
is recommended that you deflect the
door farther until you can adjust the
Sensor pin directly with the Allen
wrench.
