Receivers & Transmitters

Larco offers the most space-efficient and durable wireless automatic door control devices available when combined with select Larco wall switch assemblies. The Ultra-Small Receiver and Transmitters operate at 433 MHz and employ code hopping-technology for secure activation's.

 

Receivers, 433 MHz

The receiver's operate only after learning a transmitter’s signal through a simple pairing procedure. This programming procedure eliminates the need to set dip switches and involves a simple press of the programming button located on the top cover of the receiver. Our vestibule sequencer receiver enables you to operate multiple doors with one transmitter with a user-defined delay that will help reduce heating and cooling costs.
