Stainless Steel Door Substation - Single Gang

This durable and efficient door substation is designed for use with select 2-wire intercom systems, providing reliable communication between entry points and a master station.

Key Features & Benefits

• Reliable Call Functionality – Equipped with a push-button call feature that alerts the master station with an audible tone and an illuminated LED indicator.
• Hands-Free Communication – Once the master station responds, the substation allows hands-free communication while the master operator uses push-to-talk functionality.
• Durable, Weather-Resistant Construction – Built with a 12-gauge stainless steel faceplate, this substation is designed to withstand harsh environments. The waterproof and puncture-resistant speaker ensures long-lasting performance.
• Secure & Tamper-Resistant – Includes tamper-proof screws and a T-10 TORX bit for secure installation.
• Simple Wiring & Installation – Requires only two-conductor wiring to connect to the master station. The substation mounts flush into a standard 1-gang electrical box (not included).
• Wide Temperature Tolerance – Built to perform in extreme temperatures, from -67°F to 185°F (-55°C to 85°C) for the speaker and -40°F to 257°F (-40°C to 125°C) for the switch.

Technical Specifications

• Power Source – Supplied by the master station
• Speaker – 20 ohms, 4W, 1.92" square, waterproof and puncture-resistant
• Call Button – SPST; call tone rings at the master station while the button is held
• Faceplate Material – 12-gauge stainless steel
• Mounting – Flush mount into a 1-gang box (not included)
• Terminations – Color-coded, prewired pigtails
• Dimensions (H x W x D) – 4-1/2" x 2-3/4" x 1-5/8"

Important Notes

• No Substation-to-Substation Communication – Substations can only communicate with the master station.
• Independent Wiring Required – Each substation must have its own direct wiring to the master station (cannot share wiring).

Ideal for secure entry points, industrial applications, and high-traffic environments, this substation delivers clear communication, durability, and ease of installation.
