Versatile and Functional
The ML-1100 mortised electromagnetic locks
are ideal for many different applications.
These mortise locks can be utilized with the
Dortronics DPA door pulls for an attractive
architectural appearance, while providing
unsurpassed security functionality.
Using the DPA series pull with a ML series
mortise lock allows the force of the magnet to
be directly opposite the direction of pull; therefore
no mechanical advantage is gained when
force is applied to the pull handle. There is no
chance of racking the door. Steel or aluminum
framed doors are susceptible to permanent
damage when the lock is header mounted and
the door handle is pulled repeatedly (while the
door is locked).
These locks and door pulls were first utilized
in New York City’s Public Housing projects.
The high level of use combined with the need
to conform Architecturally and Functionally
led to a truly tough yet appealing design. All
fasteners are Stainless Steel and Tamper-proof.
The design allows the ML Series lock fasteners
to be totally concealed when the door is closed
In areas where aesthetics are a concern, the
DPA series pull handle with the ML-1100
series lock allows concealment of the locking
hardware. This pull handle is an attractive
option for lobby and vestibule entrances. These
pulls may be custom engraved and supplied in
plated or anodized finishes.
All Dortronics electromagnetic locking devices
are fail-safe, releasing instantly upon command
or loss of power. With no moving parts to
wear, stick or bind, and no mechanical linkages
to bend or break, locking and unlocking is
accomplished with ease and efficiency.
ML series locks can be controlled individually
or simultaneously from one or many locations.
The status of the lock may be monitored by
any card access system via the optional MBS
(magnetic bond sensor) which signals that the
lock is properly energized and is holding. The
well confined magnetic field allows these locks
to be used in computer rooms and other electronically
The ML series mortised electromagnetic
locks are mounted by cutting a hole into
the door frame per the template provided.
All wiring connections are made to the
flying leads from the magnet. Two lock
mounting blocks are then attached to the
frame utilizing two of the four tapped
holes. The ML series magnet is then
attached to the mounting blocks via the
remaining tapped holes.
DPA Door Pull Mounting:
Utilizing the template provided, drill thru
the door edge in 4 places. Mount the pull
handle with the tamper-proof hardware.
A specially designed shoulder screw is
provided to insure proper floating action
of the door mounted armature. This
mounting screw can be fully tightened
without affecting floating action.Specifications
