The LiftMaster TLS1CARD Card (Timer Light Status Logic) is an OEM plug-in logic board designed for select LiftMaster commercial door operators to add timer-to-close automation and traffic light status control. Once installed, the card enables the operator to automatically close a sectional or rolling door after a programmed hold-open period and to drive a red/green dock traffic light so vehicle and pedestrian traffic can see when it is safe to proceed. This makes it a practical replacement part or upgrade for warehouses, distribution centers, parking facilities, and other commercial/industrial applications that require clear visual signaling and consistent door closing behavior.
The TLS1CARD integrates with compatible LiftMaster operator control logic and provides dedicated connections for a LiftMaster traffic light, such as the RGL24LY, while following the door’s motion and safety inputs to set the correct light state. Installation typically involves plugging the card into the operator’s designated expansion port and completing low-voltage control wiring per the operator and accessory manuals, followed by programming the desired timer-to-close behavior and light status logic from the operator controls. For safety and code compliance, the system must be used with properly installed, monitored entrapment protection devices and should be set up by a qualified door systems technician. If you are purchasing the TLS1CARD as a replacement or new accessory, verify compatibility with your specific LiftMaster commercial operator model and control logic generation before ordering.
