The SPDT reed switch (mounted within the lock
cavity) eliminates the need for extra sensors to
be installed on the door for notification of
security or access control systems.

The DP option comes with a magnet pre-
installed into the armature plate for signaling
the reed switch in the housing when the door is
closed.
NOTE: Ensure DP is operating correctly during final
testing.
•
Availability
- The Door Position Sensor may be
ordered as either a factory option or a field
installed accessory.
•
Ordering
- When both the DP and TS are added
together as a field accessory, they must be
ordered as a combination to ensure proper fit.
