PT-310S Processor/Transmitter

Fig. 1

Introduction

The PT-310S Processor/Transmitter is the latest evolution of the Eagle/Telonics remote intrusion detection system. The PT-310S detects seismic events, whereas its cousin, the PT-310IM, detects infrared or magnetic events. The unit's small size and 1.5 watt RF power output makes the PT-310S ideal for short-term covert deployments. The PT-310S is user-friendly, allowing the user to configure all field-adjustable parameters via rotary and DIP type switches.

The PT-310S works with either a seismic detector and has the ability to discriminate between vehicles and pedestrians and send separate identifying messages. Users can order the PT-310S with either a digital or voice message format compatible with all EIDS equipment, including receivers and repeaters. The digital coded message can be either the modified Manchester code or the SEIWG 005 code. Any standard VHF receiver can receive the voice messages; the voice messages also include CTCSS subaudible tones. By connecting a remote antenna to the PT-310, users can extend the transmission range.

The electronics are sealed in an aluminium housing with a removable battery case to facilitate easy battery replacement. The standard power supply, two MN1604 batteries (standard 9V transistor batteries), provides up to 90 days of operational life. An on/off, sensitivity selector switch is outside the case; all other adjustments are made inside the battery compartment. The switches inside the battery compartment allow users to select the unit ID number, transmission delay time, transmit frequencies (selectable between two pre-programmed frequencies), CTCSS tone (voice units), and the footstep counter/animal filter. Using a smart cable and appropriate PC software, users can make frequency changes over an 8 MHz bandwidth.

Eagle Telonics can sell products only to law enforcement, military, and government agencies; these products are for use only within such agencies.

Service Commitment

Since 1970, Telonics has built a reputation based on product quality, product support, service, and customer satisfaction. Telonics strives to produce the highest quality products, and to support those products accordingly.

Because of extreme conditions and the unpredictable nature associated with most telemetry applications, problems occasionally arise. Most problems can be resolved quickly. In all cases, we hope to be able to work in partnership with users to resolve problems to the user's satisfaction and to uphold our demonstrated commitment to excellence. If problems should arise, all products must be returned to our factory for failure analysis.
