Walker PTT-KM-EM-95-00 Push-To-Talk Black Handset

The Walker PTT-KM-EM-95-00 is a professional, unamplified push-to-talk handset engineered for reliable communication in installations where significant distance separates the operator from the central radio equipment. This model provides a direct, tactile interface for keying transmitters, combining a standard push-to-talk function with a substantial 95-foot hybrid cable system. It is designed for dispatchers, security personnel, and control room operators stationed far from equipment racks in large facilities, providing a dependable hardwired link that ensures consistent transmitter control and clear audio without signal degradation over long runs.

Core Functionality: Push-to-Talk Control and Hybrid Cable System

The handset’s primary function is its momentary push-to-talk (PTT) switch, which provides positive physical feedback to key a connected radio transmitter for clear voice communication. The “EM-95” specification indicates a hybrid cable assembly: a lengthy straight cable (typically 80 feet) terminated with a coiled cord (approximately 15 feet).

This unique design delivers maximum installation reach to remote equipment while providing essential operator-side flexibility and strain relief. The coiled section manages desk clutter and accommodates movement, while the long straight segment allows installation in large control rooms, extended gatehouses, or between buildings.

Design, Construction, and Integration Specifications

Built for durability, this handset features a high-impact black housing designed to withstand daily professional use. It utilizes a standard, unamplized dynamic microphone and receiver (“K-Style”) for natural, clear audio transmission and reception.

The design prioritizes reliability and simplicity, with no internal amplification or external power required. Its standard wiring and connector ensure direct plug-and-play compatibility with a wide range of common radio console interfaces, amplifier panels, and dispatch systems that accept a standard PTT input and audio circuit.

Target Applications in Large-Scale and Distributed Facilities

The PTT-KM-EM-95-00 is specifically designed for challenging installations where conventional handset cords are insufficient. Ideal applications include security kiosks at the perimeter of large complexes, remote dispatch positions in transportation hubs, utility substation control points, and any operational console located a significant distance from the central communications closet.

It solves the critical problem of maintaining direct, reliable PTT control and audio quality over distances that would compromise the performance of standard-length handsets, eliminating the need for signal repeaters or complex interface boxes.
