Liftmaster SW425 Standard Features
-  DC operator system - Powered by a 12VDC motor, this system provides exceptional starting torque.-  Slow
start/stop - Reduces the stress and shock to a gate system during starting and stopping. This promotes longer
gate and operator life.
-  Electronic braking - The electronic brake system adds substantial gate position control. Especially important
on high-cycles gates, this ensures consistent gate stops without coasting.
-  Inherent obstruction sensing - Internal system provides separate force adjustments for the open and close
directions. This allows the operator to be individually tailored for the specific gate installation and conditions.
-  External obstruction sensing - Input connections are provided for external contact and non-contact sensors,
such as photo-eyes and edge devices.
-  Control inputs - Control inputs allows the connection of a full range of optional external devices like loop
detectors, telephone entry systems, access control systems and radio receivers.
-  Single/dual gate operation - Allows operation of 2 separate gate operators in unison at a single entrance.
Assures consistent, simultaneous open/close cycle for both operators.
-  Timer to close - Adjustable timer can be set from 0 to 45 seconds. The unit will automatically reset upon
receiving and additional open commands.
-  Maximum run timer - Protects against damage to the gate and operator by limiting the unit's maximum run
time to 300 seconds.
-  LED indicators - Operator input, status and diagnostic LEDs simplify setup and troubleshooting.
-  Limit switches - All driven limit switches and limit nuts are fully adjustable, adding considerable convenience
to unit installation and maintenance.
-  External manual disconnect - External system allows the user to manually operate the gate easily and
efficiently during a power outage.
-  Post mount - Standard post-mount installation. Posts included.

Optional equipment
Battery-run system* - Provides complete operation of the gate operator, including all DC control devices and
sensing devices.
Solar panel system* - Provides complete operation of the gate operator through the use of combined solar
panel and battery system.
