Specifications

• Output Format
  Transmitters are sequentially coded in the industry standard 26­bit Wiegand format, with exact number sequences. The Transmitter has an external number printed on the ID label found on the back of the Transmitter. Specific coding details, including internal number, facility code, and ID range can be found on the LRT-4 order form on page 4 of the Product Manual.
• Enrollment
  Transmitter must be clicked twice within a Receiver’s read range to be learned upon initial Receiver power up. This synchronizes the transmitter and receiver rolling codes. If the transmitter is clicked more than five times outside of the Receivers read range the transmitter and receiver will be desynchronized. To re-sync, click twice again within read range.
• Time-Out
  LRT-4 transmitters make use of a time-out feature to preserve battery life and prevent interference with other transmitters in the field. When a button is held down continuously the transmitter will transmit the code once and shutdown and will power up once the button is released.
• Range
  Up to 400ft line of sight.
• Battery Replacement
  Transmitters include a replaceable CR2032, 3.3V, lithium battery. The battery should be replaced when a button press does not result in a flash of the LED, reliable read range, and/or an output from the Receiver
