Chamberlain Professional Products’ line of LiftMasterÒ Elite Series Logic 3.0 Commercial Door Operators features four optional plug-in boards that provide maximum product flexibility and convenience.

The four plug-in boards help facilitate system upgrades by forgoing the need for additional wiring. Three of the boards are also backwards compatible with LiftMaster’s Logic 1.0 and 2.0 Commercial Door Operators.

The Auxiliary Contact Option Board provides dry contact relays in order to operate other devices such as external heaters, security, or warning devices. These devices can be at 24V, 120VAC, or 240VAC.

The Red Green Warning Signal Option Board is ideal for high traffic areas. This board contains a red green warning light box, and can be used with other audible devices as well. When combined with a Commercial Protector System, the Red Green warning system can give a red light signal prior to an automatic timed close.  An added feature of this option board is the down mid-stop, which allows an installer to program a stop position during the close cycle other than the close limit switch. 

The CP3 Option Board is a photo eye and failsafe edge reversing option board that supports a two or four wire fail-safe electrical edge and an additional set of photo eyes.

The FDR Interface Option Board, the newest addition to the available boards, simplifies wiring when an operator is used in conjunction with Chamberlain’s fire release devices.

The Logic 3.0 commercial door operators come with an on-board 3-channel radio receiver, an expanded Maintenance Alert System (MAS), a more robust motor, and an enhanced timer.

The Chamberlain Group, Inc. manufactures and markets residential garage door openers, commercial door operators, residential and commercial gate operators, telephone entry systems and related access control products.
