LiftMaster SL575 Spec Sheet
SL 575
reliable continuous-duty
operator for use on heavy-gate
applications in commercial
and light industrial locations
This resilient operator offers many standard features
such as dual gate operation, sequenced access
management, diagnostic LEDs and more. The SL 575
supports gate lengths up to 50 feet and gate weights
up to 1,800 pounds, making it ideal for commercial
and light industrial installations.

SPECIFICATIONS
OPERATOR SPEED
10 inches per second
built-in radio receiver
external alarm reset button
Includes a factory-installed 312HM radio receiver
for use with DIP switch and Security+® 315 MHz
remote controls. This allows for one LiftMaster®
remote control to conveniently open the gate and
additional access points. Remote controls
sold separately.
This allows for quick reset of the gate operator when
the alarm has been activated.
inherent obstruction sensing
timer to close
Adjustable timer can be set from 1 to 180 seconds.
The unit will automatically reset upon receiving any
additional open commands.
This unit’s internal obstruction sensing system offers
separate force adjustments for both the open and
closed directions. If the gate strikes an obstruction,
a closing gate will reverse to open and an opening
gate will stop.
maximum run timer
external obstruction sensing
This one-button station will halt movement of the
operator in an emergency situation and comes
standard in an outdoor weather-tight enclosure.
Input connections are provided for external contact
and non-contact sensors, such as photo-eyes and
edge devices.
advanced dual gate operation
This convenient 2-wire system allows the operation
of 2 separate gate operators in unison at a single
entrance. This advanced system provides the
added convenience of connecting accessories
to either operator.
sequenced access management
The sequenced access management (SAM) system
provides the capability to sequentially control the
operator in tandem with a barrier gate.
digital logic control
Supports long-distance control wiring runs of over
1,000 feet, providing you greater flexibility of gate
operator site placement.
LED indicators
Protects against damage to the gate and operator
by limiting the unit’s run time to 120 seconds.
emergency stop button
maglock control
A dedicated control relay is provided to activate and
deactivate an optional magnetic lock for securing
the gate.
control inputs
Control inputs allow the connection of a full range
of optional external devices like loop detectors,
telephone entry systems, access control systems
and radio receivers.

warning device
surge & spike protection
UL325-compliant entrapment warning alarm has the
ability to be set for pre-operation warning. This will
provide a 3-second warning prior to and during
gate movement.
hinged access cover
A full range of inputs are available to support exit,
shadow and interrupt loop detectors.
OPERATOR WEIGHT

The mechanical braking system adds substantial
gate position control at all points in travel. This
solenoid-actuated brake system also prevents the
gate from being back-driven.
Operator input, status and diagnostic LEDs simplify
setup and troubleshooting.
