LR-911 2.6H3 1 INTRODUCTION AWID's Sentinel-Prox LR-911 2.6H3 is a long-range (9 to 11 feet) Radio Frequency IDentification (RFID) reader that works with paper-thin passive windshield mouting tags or credit card size tags. This reader comes with a unique combination of long read range, small size, and low power consumption. It has an internal power converter, allowing it to work with a wide range of supply inputs without affecting its performance.

LR-911 2.6H3 3 3.1 PREPARATION FOR INSTALLATION SITE SURVEY Always conduct a site survey before starting installation. Avoid any possible sources of interference. If the reader is not installed properly, the performance will be degraded or more seriously the reader may get damaged. Listed below are steps that should be followed during installation: • Do not install reader in an area where sources of broadband electromagnetic noise may exist.

Be sure to elevate the antenna slightly to accommodate sport utility vehicles, minivans and trucks. 3.4 GENERAL WIRING REQUIREMENTS All the reader wiring should be continuously shielded. AWID recommends using #22 AWG up to #18 AWG, longer distances and higher current consumption on the power supply line will require larger gauge wires. Due to system data termination differences, contact your panel manufacturer for the proper wire sizes to meet their specific requirements. TABLE 3.
LR-911 2.6H3 The Reader’s Blue wire is Signal Ground. It must be connected to the signal-return at the panel or reader-input module. This is commonly (but not always) the panel ground terminal. Figure 1 Figure 2 Wiegand Output Format RS-232 Output Format The Reader’s Yellow wire enables the Reader to function only when this line is pulled low (0 V) by a dry contact or by connection to ground.
