Introduction
The LB-1 Letter Beacon is a micropower, credit card sized transmitter that operates in the VHF band (150-
174 MHz). It is used for event monitoring and package tracking purposes by law enforcement agencies.
The beacon emits short-duration, low-power radio signals. The LB-1 reports status, event and motion
information as well as battery condition with low-duty cycle transmissions, thus greatly increasing the
unit’s battery life. The reporting tone codes may be customized by the user using a software package. The
LB-1 is also capable of transmitting unmodulated tracking pulses for pseudo-doppler type tracking
receivers such as the DTC TRAK/R-2000.
The device may also be programmed to begin or cease transmissions on a schedule based on a real-time
clock. Both the batteries and the antenna are internal to the unit.
The LB-1 is a self-contained beacon featuring:
• DTMF tone generation
• Multi-tone generation
• Tracking Pulse capability
• Breakwire capability
• Standby capability
• User programmability
• Delayed operation mode
• Scheduled operation mode
• Reliable battery contacts with no battery compartment door to lose
• Unique “tape-down” contacts for fine wires (Breakwire and Standby)
• Operator interface through an on-board button and LED
• Special status tones transmitted to indicate low battery and motion
• On-board motion detection
• Integrated, optimized antenna
