Automated battery backup - the unit continues to work on batteries with full functionality (but does move more slowly) until the unit gets to about 75% of battery capacity then transitions to push and hold operation.
The 300 series also works with and powers 12V automatic lock systems
Option available: 5-conductor cable (5') to reduce the risks of miswiring incidents available in 5' 10' 15' 20' or 25' lengths
Integrated software fuse that shuts down the unit to help prevent board component disasters should these be incorrectly installed on grossly imbalanced or improperly sized doors.
30:1 40:1 50:1 gearbox ratio are available. Please specify when ordering
Laser-based sensor system for automatic swing doors.
Time-of-flight technology used to eliminate the limitations of infrared-based devices.
Background independence eliminates nuisance detections caused by changing conditions while gyroscopes sense the movement of the door for accurate positioning.
Provides asjustable pattern depth.
Min/max door width: 20"-48" from leading edge of sensor LED
Mounting height: 75"-98" from finished floor to sensor LED
May be used in two different ways: as an OPEN only control (all LiftMaster operators) or as an OPEN/CLOSE control (only LiftMaster operators with types B2 and S2 control wiring).
In the latter case pulling the cord will open a fully closed door close a fully opened door and reverse a closing door.
Pulling the cord whlie the door is opening will either have no effect (type B2 wiring) or will stop the door (Solid State Logic Control Board).
IMPORTANT NOTE: The new safety reversing sensor brackets are only compatible with the new safety reversing sensors (041-0136) and are NOT compatible with older style safety reversing sensors.
For safety reversing sensor brackets compatible with models pre-2021 refer to 041A5266-3.
