1) Optional Monitoring Outputs:
•
Using the provided 7/32 hex wrench, raise
or lower the armature as needed.
> Clearance between magnet and armature
is recommended to be 1/8”,
and must be less than 1/4”.
Door Status Monitor (DSM)
The optional DSM provides a dry set of contacts for monitoring “door open” or
“door closed” conditions.
Magnetic Bond Sensor (MBS)
The optional MBS provides a dry set of contacts for monitoring “door locked” or “door
unlocked” conditions. The MBS measures the magnetic holding force between the
armature and the magnetic coil. Poor magnetic bond is the result of low voltage,
foreign material between the surfaces of the magnetic coil and armature, or
improper alignment of magnet and armature.
