Overview
M400 Series electromagnetic locks from Schlage are designed with the customer in
mind to be robust, easy-to-install, and secure. The unique bayonet mounting feature
makes installation easier, allowing the installer to have their hands free during the
mounting process.
All M400 Series electromagnetic locks are symmetrical with field-selectable handing,
allowing optimum placement of the magnet, no matter the application. They are
designed to provide automatic voltage sensing for 12 and 24 volts along with polarity
protection to make wiring less complex. M420 models are tested and certified to meet or
exceed UL 1034 and BHMA 500 lb hold force requirements.
The M420 electromagnetic locks come in four configurations to meet your specific
security needs. Single and double door models are oered in standard configurations.
Plus versions of these models with “P” designations add intelligent sensing and reporting
features needed to integrate with access control systems along with additional available
options. Kits are available for top jam, double door, and glass door applications.

Additional features
All models
§Automatic Voltage Selection (AVS)
senses the voltage applied to the lock
and responds accordingly
M420P/M422P

the strength of the bond between the
lock and armature so you know the door
is secure
§Door Position Switch (DPS) monitors
whether the door is open or closed
§Relock Time Delay (RTD) provides a
relock delay that is adjustable from
0.5 to 30 seconds
§Optional accessories (P models only)
ATS/LED Combines anti-tamper switch
(ATS) with magnetic bond sensor in one kit.
- ATS provides an indication that
the cover of the magnet is securely
fastened to the lock and that the on
board circuitry is secure
- Magnetic bond sensor indicator (LED)
provides visual indication of magnetic
bond at the lock
Optional accessories (for all)
§Herculite door bracket kit
