Walker PTT-FM-EM-80-00 Push-To-Talk Handset for Nortel Meridian

Walker PTT-FM-EM-80-00 Push-To-Talk Handset for Nortel Meridian

The Walker PTT-FM-EM-80-00 is a specialized professional communication device designed as a direct replacement and upgrade component for legacy Nortel Meridian 1 telephone systems. This industrial handset integrates a dedicated push to talk, or PTT, function with an extended reach cable, creating a reliable interface for users who require instant transmission control in console and dispatch environments. It serves as a critical tool for maintaining clear and immediate communication within facilities still operating on this robust, enterprise-grade telephony platform.

Core Functionality and System Integration for Meridian Phones

This unit's primary feature is its momentary push to talk switch, which provides tactile, positive control to key the microphone for transmission. Unlike a standard telephone handset, this allows the user to quickly broadcast to a party line, intercom, or radio system connected to the Meridian PBX. The "FM" designation refers to a specific microphone style and frequency response optimized for voice clarity within the system's parameters. It is engineered to connect directly to compatible Nortel Meridian digital telephone sets, utilizing the existing handset port and drawing power and audio signaling without requiring external adapters or complex wiring modifications.

Technical Specifications: Extended Cable and Durability Features

A key specification of this model is its substantial 80 foot straight cable, denoted by "EM-80-00" in the product number. This extended length provides exceptional installation flexibility, allowing the handset to be positioned far from the base telephone—ideal for control rooms, security desks, or manufacturing floors where the operator needs mobility within a defined area. The handset is built with a durable, high impact housing designed to withstand the demands of 24/7 professional use, ensuring longevity in mission-critical communication scenarios.

Application in Industrial, Security, and Dispatch Environments

This handset is purpose-built for professional settings where a Nortel Meridian system forms the communication backbone. Its typical applications include:

• Industrial Dispatch: Manufacturing plant floors where supervisors need instant, plant-wide intercom access.

• Security Command Centers: Console positions where guards must quickly broadcast alerts or coordinate with patrols.

• Transportation Hubs: Logistics offices requiring reliable, direct line communication across a large facility.

• Utility Control Rooms: Operational centers managing field technicians via connected radio systems.

It is the ideal solution for upgrading a standard Meridian phone into a dedicated dispatch point without overhauling the entire telephony infrastructure.
