Walker W6-K-M-EM-80-RP-00 Amplified Telephone Handset

Walker W6-K-M-EM-80-RP-00 – Amplified Telephone Handset with Reverse Polarity for Nortel Systems

The Walker W6‑K‑M‑EM‑80‑RP‑00 is a professional amplified handset designed for use with Nortel Meridian telephone systems (Meridian 1, SL‑1, Norstar) and other applications requiring reverse polarity wiring. This black handset features a built‑in amplifier to boost incoming audio, a noise‑canceling electret microphone (EM) for clear outgoing voice, and a rugged, vandal‑resistant construction. The “RP” designation indicates reverse polarity wiring, matching the specific pinout of Meridian consoles, paging adapters, and compatible emergency phone systems. It is ideal for noisy dispatch centers, security command posts, public help phones, and paystations where standard handsets fail to provide sufficient volume or clarity.

How It Works

The handset connects to your Nortel Meridian console, paging adapter, or compatible phone base via the included heavy‑duty armored coiled cord (modular RJ12 or RJ45). The “reverse polarity” means the tip and ring wiring for the microphone and speaker are swapped compared to a standard telephone handset, ensuring correct operation with Meridian equipment (no adapters needed). The built‑in amplifier boosts incoming audio levels, making dispatcher instructions audible even in high‑noise environments. The noise‑canceling electret microphone reduces background noise (e.g., office chatter, machinery) so your voice is transmitted clearly. When the user lifts the handset, the hook switch signals the system to go off‑hook. For a complete dispatch setup, pair this handset with a comfortable corded headset from FindHeadsets – ideal for staff who need hands‑free monitoring alongside the handset.

Compatibility & Design

The Walker W6‑K‑M‑EM‑80‑RP‑00 is specifically designed for Nortel Meridian 1, Meridian SL‑1, Norstar systems, and other Meridian PBX consoles that require reverse polarity wiring. It is a direct replacement for legacy amplified handsets on operator positions, paging adapters, and public help interfaces. The handset housing is constructed from high‑impact, UV‑stabilized thermoplastic with a black, non‑reflective finish. The armored coiled cord is reinforced against cutting and stretching, extending to over 6 meters (20 feet). The noise‑canceling electret microphone (EM) provides a wideband response, while the dynamic receiver is amplified for high output. The handset includes a built‑in hook switch actuator compatible with magnetic or mechanical cradles. It is IP65 rated for dust and water resistance, operates from -40°C to 70°C, and is hearing aid compatible (HAC). All exposed screws are vandal‑resistant. The reverse polarity wiring is preset; no field modification is required.

Why Choose This Product

Standard telephone handsets lack the volume and voice clarity needed for noisy dispatch centers or public phones. The W6‑K‑M‑EM‑80‑RP‑00’s built‑in amplifier boosts incoming audio, while the noise‑canceling microphone ensures your voice is heard clearly. The reverse polarity feature eliminates the need for custom wiring or adapters when connecting to Nortel Meridian systems – just plug it in. The rugged, vandal‑resistant construction reduces maintenance in high‑traffic or outdoor installations. For facility managers, this handset is a direct drop‑in replacement for worn or underperforming units, improving safety and user satisfaction. The classic “K” (traditional) shape is familiar and comfortable for all users.
