Walker W7-K-M-EM-95-00 Amplified Transmitter Telephone Handsets

Walker W7-K-M-EM-95-00 – Amplified Transmitter Handset for Nortel Meridian Dispatch Systems

The Walker W7-K-M-EM-95-00 is a professional, amplified transmitter handset designed specifically for Nortel Meridian phone systems (Meridian 1, SL‑1, Norstar) and compatible dispatch consoles. This rugged black handset features a built‑in amplifier that boosts outgoing audio (transmitter) – ideal for users who need to be heard clearly in noisy dispatch centers, security command posts, or industrial control rooms. The noise‑canceling electret microphone (EM) reduces background chatter, while the amplified transmitter ensures your voice cuts through ambient noise without straining. Built to withstand heavy daily use, the W7 handset includes a reinforced coiled cord and vandal‑resistant construction, making it a reliable upgrade or replacement for legacy Meridian PTT handsets.

How It Works

The handset connects directly to a Nortel Meridian console, paging adapter, or telephone system via the included modular cord (RJ12 or RJ45). The “amplified transmitter” means the internal amplifier boosts the microphone signal before it reaches the phone system, increasing the user’s voice level – particularly useful for quiet talkers or noisy rooms. The noise‑canceling electret microphone filters out background noise, ensuring that the person on the other end hears a clear voice. The handset works in both standard telephone mode and push‑to‑talk (PTT) mode, depending on system configuration. The dynamic receiver provides clear incoming audio, and the hook switch supports cradle operation. For a complete communication center, pair this handset with a comfortable corded headset from FindHeadsets – ideal for dispatch staff who also need hands‑free monitoring.

Compatibility & Design

The Walker W7-K-M-EM-95-00 is specifically designed for Nortel Meridian 1, Meridian SL‑1, Norstar systems, and other Meridian PBX consoles that support amplified transmitter handsets. It is a direct replacement for legacy handsets on Meridian operator positions and paging adapters. The handset is constructed from high‑impact, flame‑retardant ABS plastic with a reinforced, kink‑resistant coiled cord (approx. 2.5 meters retracted, extending to over 6 meters). The electret microphone (EM) provides a wideband response and noise cancellation, while the amplifier is factory‑tuned for optimal gain. The receiver is dynamic for reliability. The handset includes a hook switch for cradle operation. It operates from -20°C to 60°C and is IP54 rated for dust and splash resistance. The black finish is scuff‑resistant. All exposed screws are vandal‑resistant (Torx).

Why Choose This Product

Standard telephone handsets often lack the microphone gain needed for noisy dispatch environments. The W7’s amplified transmitter ensures your voice is heard clearly, reducing repeats and misunderstandings. The noise‑canceling microphone is critical in busy control rooms, filtering out office chatter and equipment hum. The rugged construction outlasts consumer‑grade handsets, lowering replacement costs. For facility managers, this handset is a direct drop‑in replacement for worn or damaged Meridian PTT units, with simple plug‑and‑play installation. The “EM” designation indicates an electret microphone with enhanced sensitivity.
