Larco, a leading manufacturer of automatic door activation and safety products, has developed revolutionary new transmitters and receivers designed for compatibility with virtually all automatic door operators and control devices. 

The ultra-small transmitters measure 1.25” x 0.875” x 0.25” and the receivers measure 2.25” x 1.25” x 0.75”, making them the smallest and most versatile on the market. Their ultra-small size and excellent range makes it easy to locate the receiver inside the header, maintaining the clean architectural lines of the installation and reducing vandalism. 

In addition to size benefits, the new transmitter and receiver units offer an improved signal range. The self-learning receiver unit offers millions of code variations for increased security and eliminates dipswitch settings. Receiver relays can be programmed for momentary contact output or to latch up until a second activation is received. The momentary contact output also is adjustable from one second to four hours, and the receiver can memorize codes from up to 12 different transmitters. The units are factory pre-wired so installation is as easy as attaching the battery and pushing the programming buttons.  Both units operate at a 433 MHz frequency for use worldwide. The new transmitters and receivers have undergone rigorous testing and are FCC, Industry Canada and CE certified. 

Larco’s new transmitter and receiver units are designed for use with Larco’s shallow profile universal wall switch and jamb switch box assemblies. When combined, these two new products become the smallest, most space efficient and most durable wireless automatic door control devices available.
